What's New since 7.3?
This section was last updated in the last half of the year 2021.
This section describes the enhancements made to ILE RPG after 7.3 with PTFs.
See https://www.ibm.com/support/pages/rpg-cafe to determine the PTFs you need on the systems where you are compiling and running your programs.
If a program uses an enhancement that requires a runtime PTF, you must ensure that the runtime PTF is applied on any system where the program is restored.
- New built-in functions %MAXARR and %MINARR
-
You can find the index of the maximum value or minimum value in an array using %MAXARR
or %MINARR.
In the following example
- After the assignment from %LIST, the maximum value in the array is 'Yellow' (array1(2)). The minimum value is 'Blue' (array1(3)).
- %MAXARR(array1) returns 2.
- %MINARR(array1) returns 3. When %MINARR(array1) is used as an index for array1, the value assigned to minVal is 'Blue'.
DCL-S array1 VARCHAR(10) DIM(3); DCL-S i INT(10); DCL-S minVal LIKE(array1); array1 = %LIST('Red' : 'Yellow' : 'Blue'); // 1 i = %MAXARR(array1); // 2 // i = 2 minVal = array1(%MINARR(array1)); // 3 // minVal = 'Blue'
See %MAXARR and %MINARR (Maximum or Minimum Element in an Array).
This enhancement is available with a compile-time PTF in the last half of the year 2021.
- Sort an array data structure by more than one subfield
-
Use %FIELDS to list the subfields for sorting an array data structure.
In the following example, data structure array info is sorted by subfields dueDate and orderId. To determine the required order of two elements of info, subfield dueDate is compared first. If the value of dueDate is equal in the two elements, then subfield orderId is used to determine the order of the two elements of info.
info(2).dueDate is greater than info(3).dueDate so it is not necessary to compare the second subfield orderId to determine the relative order of elements 2 and 3.
info(1).dueDate is equal to info(3).dueDate so info(1).orderId is compared to info(3).orderId to determine the relative order of elements 1 and 3.
DCL-DS info QUALIFIED DIM(3); orderId packed(5); dueDate DATE(*ISO); quantity int(10); END-DS; info(1).orderId = 23456; info(1).dueDate = D'2021-09-08'; info(1).quantity = 5; info(2).orderId = 12345; info(2).dueDate = D'2021-10-08'; info(2).quantity = 3; info(3).orderId = 12345; info(3).dueDate = D'2021-09-08'; info(3).quantity = 25; SORTA info %FIELDS(dueDate : orderId); // info(1).orderId = 12345 // info(1).dueDate = D'2021-09-08' // info(1).quantity = 25 // // info(2).orderId = 23456 // info(2).dueDate = D'2021-09-08' // info(2).quantity = 5 // // info(3).orderId = 12345 // info(3).dueDate = D'2021-10-08' // info(3).quantity = 3
See %FIELDS (Subfields for sorting).
This enhancement is available with a compile-time PTF in the last half of the year 2021.
- See the value of named constants in the debugger
-
Specify Control keyword DEBUG(*CONSTANTS) to enable viewing the value
of named constants in the debugger.
CTL-OPT DEBUG(*CONSTANTS);
See DEBUG{(*DUMP | *INPUT | *RETVAL | *XMLSAX | *NO | *YES)}.
This enhancement is available with a compile-time PTF in the last half of the year 2021. A PTF is also needed for the debugger at compile-time and runtime.Warning: You must ensure that the debugger PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - New built-in functions %LOWER and %UPPER
-
You can convert the case of a character or UCS-2 string
to lower case using the %LOWER built-in function
or to upper case using the built-in function %UPPER.
You can limit the conversion to only part of the string by specifying the start and length for the conversion.
In the following example, the characters following the first character are converted to lower case.DCL-S string VARCHAR(20); string = %LOWER('GÖTEBORG' : 2); // string = "Göteborg"
See %LOWER and %UPPER (Convert to Lower or Upper Case).
This enhancement is available with a compile-time PTF and a runtime PTF in the first half of the year 2021.Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - New built-in function %SPLIT
-
You can split a string into a temporary array of substrings
using %SPLIT.
By default, the string is split at blanks. You can specify a second parameter with the characters you want to split at.
In the following examples, the result of %SPLIT is assigned to an array.
- In the first assignment, the string is split at blanks.
- In the second assignment, the string is split at either asterisks or blanks.
DCL-S array VARCHAR(20) DIM(10); array = %SPLIT(' **One** **Two** **Three** '); // 1 // array(1) = '**One**' // array(2) = '**Two**' // array(3) = '**Three**' array = %SPLIT(' **One** **Two** **Three** ' : ' *'); // 2 // array(1) = 'One' // array(2) = 'Two' // array(3) = 'Three'
See %SPLIT (Split String into Substrings).
This enhancement is available with a compile-time PTF and a runtime PTF in the first half of the year 2021.Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - A new option *STRICTKEYS is added to the EXPROPTS Control keyword.
-
When EXPROPTS(*STRICTKEYS) is specified, the rules are more strict for
specifying the search argument for keyed file operations using
a list of keys or %KDS.
See *STRICTKEYS.
This enhancement is available with a compile-time PTF in the first half of the year 2021.
- New built-in function %RANGE
-
You can check whether a value is in the range of two other
values by using the %RANGE built-in function.
In the following example, the IF statement is true if num is greater than or equal to 1 and less than or equal to 10.
DCL-S num PACKED(15:5); IF num IN %RANGE(1 : 10); ... ENDIF;
See %RANGE (lower-limit : upper-limit).
This enhancement is available with a compile-time PTF in the last half of the year 2020.
- New built-in function %LIST
-
You can define a temporary array by using built-in function %LIST.
%LIST is allowed in calculations anywhere an array is allowed
except SORTA, %LOOKUPxx, or %SUBARR.
In the following example, the first four elements of the libraries array are assigned from the values in the %LIST built-in function. The first element of libraries is assigned the value 'QGPL', the second element is assigned the value of variable currentUserProfile and so on.
DCL-S libraries CHAR(10) DIM(10); libraries = %LIST ('QGPL' : currentUserProfile : 'QTEMP' : getDevLib ());
See %LIST (item { : item { : item ... } } ).
This enhancement is available with a compile-time PTF in the last half of the year 2020.
- New operation code FOR-EACH
- The FOR-EACH operation code begins a group of operations that iterates through the elements
of an array, %LIST, %SPLIT, or %SUBARR.
The first operand of FOR-EACH is a variable that receives the value of the current element in the array or %LIST.
The loop ends with the ENDFOR operation code.
In the following example, each element of the filenames array is processed in the FOR-EACH group. Within the group of operation codes between the FOR-EACH operation and the ENDFOR operation, the file variable has the value of the current element of the filenames array.DCL-S filenames CHAR(10) DIM(10); DCL-S file CHAR(10); DCL-S numFilenames INT(10); ... FOR-EACH file in %SUBARR(filenames : 1 : numFilenames); process (file); ENDFOR;
See FOR-EACH (For Each).
This enhancement is available with a compile-time PTF in the last half of the year 2020.
- New IN operator
-
The IN operator is used to determine whether an item
is in an array or %LIST, or in a range.
IF item IN %RANGE(lower_limit : upper_limit); ... ENDIF; IF item IN myArray; ... ENDIF; IF item IN %LIST(item1 : item2 : ...); ENDIF;
See IN operator.
This enhancement is available with a compile-time PTF in the last half of the year 2020.
- Allow blanks for built-in functions that convert character to numeric
-
A new option *ALWBLANKNUM is added to the EXPROPTS Control keyword.
When EXPROPTS(*ALWBLANKNUM) is specified, the numeric conversion built-in functions %DEC, %DECH, %FLOAT, %INT, %INTH, %UNS, and %UNSH, a blank character value is allowed. These built-in functions return zero if the character operand is blank or it has a length of zero. For DATA-INTO and XML-INTO, if the value for a numeric field is blank or empty, a value of zero is placed in the value.
In the following example, the %DEC operation does not fail due to a blank value because EXPROPTS(*ALWBLANKNUM) is specified.CTL-OPT EXPROPTS(*ALWBLANKNUM); DCL-S num PACKED(15:5); DCL-S string CHAR(10) INZ(*BLANKS); num = %DEC(string : 63 : 15);
See EXPROPTS(*MAXDIGITS | *RESDECPOS | *ALWBLANKNUM | *USEDECEDIT) and Rules for converting character values to numeric values using built-in functions.
This enhancement is available with a compile-time PTF and a runtime PTF in the last half of the year 2020.Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - Allow thousands separators for built-in functions that convert character to numeric
-
A new option *USEDECEDIT is added to the EXPROPTS Control keyword.
When EXPROPTS(*USEDECEDIT) is specified, the numeric conversion built-in functions %DEC, %DECH, %FLOAT, %INT, %INTH, %UNS, and %UNSH interpret the period and comma characters according to the setting defined by the Control keyword DECEDIT. This keyword also affects the way the data for a numeric field is processed by DATA-INTO and XML-INTO.
By default, and with DECEDIT('.') or DECEDIT('0.'), or with DECEDIT(*JOBRUN) when the job DECFMT value is not J, the period is the decimal-point character and the comma is the digit-separator (thousands separator) character.
With DECEDIT(',') or DECEDIT('0,'), or with DECEDIT(*JOBRUN) when the job DECFMT value is J, the comma is the decimal-point character and the period is the digit-separator.
In the following example- Keyword EXPROPTS(*USEDECEDIT) is specified.
- Keyword DECEDIT keyword is not specified, so the decimal-point character defaults to the period and the digit-separator character defaults to the comma.
- The string '1,234,567.89' is allowed for %DEC. The commas are ignored because the comma is the digit-separator character.
- The %DEC built-in function returns 1234567.89.
CTL-OPT EXPROPTS(*USEDECEDIT); DCL-S num PACKED(15:5); num = %DEC('1,234,567.89' : 15 : 5);
See EXPROPTS(*MAXDIGITS | *RESDECPOS | *ALWBLANKNUM | *USEDECEDIT) and Rules for converting character values to numeric values using built-in functions.
This enhancement is available with a compile-time PTF and a runtime PTF in the last half of the year 2020.
Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - Optionally require prototypes for the main procedure and exported procedures
-
Parameter REQPREXP is added to the CRTBNDRPG and CRTRPGMOD commands to control
how the compiler responds when no prototype is specified for an exported procedure.
Additionally, the keyword REQPREXP can be specified as a Control Specification keyword.
The default for the parameter is *NO.
With the *WARN level, the compiler issues a warning diagnostic message.
With the *REQUIRE level, the compiler issues a severe diagnostic message, which causes the compile to fail.
You can specify keyword REQPROTO(*NO) for an exported procedure or for the procedure interface of the cycle-main procedure to indicate that a prototype is never required for the procedure.
See REQPREXP(*NO | *WARN | *REQUIRE), REQPROTO(*NO) for exported procedures, and REQPROTO(*NO) for the procedure interface of the cycle-main procedure.
This enhancement is available with several compile-time PTFs in the last half of the year 2020.
See https://www.ibm.com/support/pages/rpg-cafe for PTF details.
- See or change the return value from a procedure while debugging
- If Control keyword DEBUG(*RETVAL) is specified,
you can evaluate special variable _QRNU_RETVAL
to see or change the value that the procedure will return.
Set a breakpoint on the last statement of the procedure to view or change the value of this variable.
- In free-form code, set the breakpoint on the END-PROC statement.
- In fixed-form code, set the breakpoint on the Procedure-End specification.
For example, a programmer is debugging the following procedure.- The procedure returns the value 'abcde'.
- The programmer sets a breakpoint on the END-PROC statement.
- In the debug session, the programmer displays the return value.
CTL-OPT DEBUG(*RETVAL); ... DCL-PROC myProc; DCL-PI *n CHAR(10) END-PI; RETURN 'abcde'; 1 END-PROC; 2
- In the debug session at the END-PROC statement, the programmer displays the return value.
- The programmer changes the return value to '12345'.
- The value '12345' is returned from the procedure.
> EVAL _qrnu_retval 1 _QRNU_RETVAL = 'abcde ' > EVAL _qrnu_retval = '12345' 2 _QRNU_RETVAL = '12345' = '12345 '
See DEBUG{(*DUMP | *INPUT | *RETVAL | *XMLSAX | *NO | *YES)}.
This enhancement is available with a compile-time PTF in the last half of the year 2020.
- %TIMESTAMP to return microsecond precision
- %TIMESTAMP() now returns a timestamp with microsecond precision.
If you specify %TIMESTAMP(*UNIQUE), the returned timestamp has a nonzero value for all 12 fractional digits. The first 6 fractional seconds provide microsecond precision. The final 6 digits are used to create a unique timestamp.
See %TIMESTAMP (Convert to Timestamp).This enhancement is available with a compile-time PTF and a runtime PTF in the first half of the year 2020.
Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - A variable or expression is allowed for the second parameter of %KDS
- The second parameter of %KDS is the number of keys to use for
the keyed operation.
You can now specify a variable or expression for the second parameter.
DCL-F myfile KEYED; DCL-DS keys LIKEREC(myRec : *KEY); DCL-S numKeys INT(10); numKeys = 3; CHAIN %KDS(keys : numKeys) myRec; READE %KDS(keys : numKeys - 1) myRec;
This enhancement is available with a compile-time PTF and a runtime PTF in the first half of the year 2020.
Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - Qualified name for the LIKEDS keyword
- You can now specify a qualified name for the LIKEDS keyword.
In the following example
- Data structure subfield employees is defined directly in data structure employee_info.
- The LIKEDS keyword for the parameter for procedure check_employee is defined by using the LIKEDS keyword to define the parameter the same as the qualified subfield employee_info.employeeds.
DCL-DS employee_info QUALIFIED; num_employees INT(10); DCL-DS employees DIM(20); // 1 name VARCHAR(25); salary PACKED(7:2); END-DS; END-DS; DCL-PR check_employee IND; employee LIKEDS(employee_info.employees); // 2 END-PI;
This enhancement is available with a compile-time PTF in the last half of the year 2019.
- *ON and *OFF can be logical expressions
- You can now use *ON and *OFF directly in conditional statements.
For example, if you want an infinitely DOW loop, you can code "DOW *ON".
DOW *ON; ... ENDDO;
This enhancement is available with a compile-time PTF in the last half of the year 2019.
- New operation code DATA-GEN
- DATA-GEN generates a structured document, such as JSON or CSV, from
an RPG variable.
It requires a generator to generate the document.
The DATA-GEN operation calls the generator, passing it the names and values of the
RPG variables, and the generator passes the text for the structured document
back to the DATA-GEN operation, which places the
information into the output file or the output RPG variable.
See DATA-GEN (Generate a Document from a Variable), %DATA (document {:options}), %GEN (generator {: options}).
DCL-DS product QUALIFIED; name VARCHAR(25); id CHAR(10); price PACKED(9 : 2); END-DS product; DATA-GEN product %DATA('ProductInfo.JSON' : 'doc=file') %GEN('MYLIB/MYJSONGEN');
This enhancement is available with a compile-time PTF and a runtime PTF in the last half of the year 2019.
Warning: You must ensure that the runtime PTF is applied on any system where the program is restored. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - Overloaded prototypes
-
The OVERLOAD keyword defines a list of other prototypes that can be called
by using the name of the prototype with the OVERLOAD keyword.
When the prototype with the OVERLOAD keyword is used in a call operation, the compiler uses
the parameters that are specified for the call to determine which of the candidate prototypes
that are listed in the OVERLOAD keyword to call.
In the following example, FORMAT is defined with the OVERLOAD keyword.
- For the first call to FORMAT, the parameter has type Date, so FORMAT_DATE is called.
- For the second call to FORMAT, the parameter has type Time, so FORMAT_TIME is called.
- For the second call to FORMAT, the parameters have type Character, so FORMAT_MESSAGE is called.
See OVERLOAD(prototype1 { : prototype2 ...}).DCL-PR format_date VARCHAR(100); dateParm DATE(*ISO) CONST; END-PR; DCL-PR format_time VARCHAR(100); timeParm TIME(*ISO) CONST; END-PR; DCL-PR format_message VARCHAR(100); msgid CHAR(7) CONST; replacement_text VARCHAR(100) CONST OPTIONS(*NOPASS); END-PR; DCL-PR format VARCHAR(100) OVERLOAD(format_time : format_date : format_message); DCL-S result varchar(50); result = format(%date()); // 1 result = format(%time()); // 2 result = format('MSG0100' : filename); // 3
This enhancement is available with a compile-time PTF in the last half of the year 2019.
- OPTIONS(*EXACT) for prototyped parameters
-
When OPTIONS(*EXACT) is specified for a prototyped parameter, additional rules apply to ensure that
the called procedure receives the same value as the passed parameter.
For example, without OPTIONS(*EXACT), the compiler allows the passed parameter to be longer than the prototyped parameter,
and it allows a data structure to be passed that is related by LIKEDS to a different data structure from the passed parameter.
With OPTIONS(*EXACT), the passed parameter cannot be longer than the prototyped parameter, and if the prototyped
parameter is defined with LIKEDS keyword, the passed parameter must be related by LIKEDS to the same data structure.
In the following example, field fld10 can be passed to parameter parm5 of prototype p1, but the called procedure receives the value "abcde" instead of the full value 'abcdefghij' of fld10.
Field fld10 cannot be passed to parameter parm5Exact of prototype p2 because the length, 10, of fld10 is greater than the length, 5, of the prototyped parameter parm5Exact.
See OPTIONS(*EXACT).dcl-pr p1; parm5 char(5); end-pr; dcl-pr p2; parm5Exact char(5) OPTIONS(*EXACT); end-pr; dcl-s fld10 char(10) inz('abcdefghij'); p1 (fld10); p2 (fld10); // Error
This enhancement is available with a compile-time PTF in the last half of the year 2019.
- SAMEPOS keyword
-
The SAMEPOS keyword positions a subfield at the same starting position as another subfield.
See SAMEPOS(subfield).
This enhancement is available with a compile-time PTF in the first half of the year 2019.
- New PSDS subfields
-
The following new subfields are added to the Program Status Data Structure:
- Internal job ID, in positions 380 - 395.
- System name, in positions 396 - 403.
See Program Status Data Structure
This enhancement is available with a runtime PTF in the first half of the year 2019.
Warning: You must ensure that the runtime PTF is applied on any system where the enhancement is required. See https://www.ibm.com/support/pages/rpg-cafe for PTF details. - New operation code DATA-INTO
- DATA-INTO reads data from a structured document, such as JSON, into
an RPG variable.
It requires a parser to parse the document.
The DATA-INTO operation calls the parser, and the parser passes the information in
the document back to the DATA-INTO operation, which places the
information into the RPG variable.
See DATA-INTO (Parse a Document into a Variable), %DATA (document {:options}), %PARSER (parser {: options}).
DCL-DS product QUALIFIED; name VARCHAR(25); id CHAR(10); price PACKED(9 : 2); END-DS product; DATA-INTO product %DATA('ProductInfo.JSON' : 'doc=file') %PARSER('MYLIB/MYJSONPARS');
This enhancement is available with a compile-time PTF and a runtime PTF in the first half of the year 2018.
This enhancement is also available in 7.2 with compile-time and runtime PTFs.
Warning: You must ensure that the runtime PTF is applied on any system where the program is restored.If you compile your program with TGTRLS(*V7R2M0), different runtime PTFs are required for 7.2 and 7.3 systems. See https://www.ibm.com/support/pages/rpg-cafe for PTF details.
- Built-in function %PROC()
- %PROC() returns the external name of the current procedure.
See %PROC (Return Name of Current Procedure).
This enhancement is available with a compile-time PTF in the last half of the year 2017.
This enhancement is also available in 7.2 with a compile-time PTF.
- More places that complex qualified names can be used
- Complex qualified names are now allowed in the following places:
- Built-in function %ELEM. See %ELEM (Get Number of Elements).
- Built-in function %SIZE. See %SIZE (Get Size in Bytes).
- Operation code DEALLOC. See DEALLOC (Free Storage).
- Operation code RESET. See RESET (Reset).
This enhancement is available with a compile-time PTF in the first half of the year 2017.
This enhancement is also available in 7.2 with a compile-time PTF.
- Nested data structure subfields
-
When a qualified data structure is defined with free-form syntax,
a subfield can be directly defined as a nested data structure subfield.
The street subfield in the following data structure
is referred to as product.manufacturer.address.street.
See Nested data structure subfield.
DCL-DS product QUALIFIED; name VARCHAR(25); id CHAR(10); DCL-DS manufacturer; name VARCHAR(10); DCL-DS address; street VARCHAR(50); city VARCHAR(25); END-DS address; active IND; END-DS manufacturer; price PACKED(9 : 2); END-DS product;
This enhancement is available with a compile-time PTF in the first half of the year 2017.
This enhancement is also available in 7.2 with a compile-time PTF.
- New built-in functions %MAX and %MIN
-
%MAX returns the maximum value of its operands. %MIN returns the minimum value of its operands.
There must be at least two operands, but there is no upper limit on the number of operands when
%MAX or %MIN are used in calculations. When %MAX or %MIN are used in Declaration statements, there
must be exactly two numeric operands.
In the following example, after the assignment operations, maxval has the value 'Zorro' and minval has the value 'Batman'.
See %MAX and %MIN (Maximum or Minimum Value).DCL-S maxval VARCHAR(10); DCL-S minval VARCHAR(10); DCL-S name1 VARCHAR(20) INZ('Robin'); DCL-S name2 VARCHAR(10) INZ('Batman'); maxval = %MAX(name1 : name2 : 'Zorro'); minval = %MIN(name1 : name2 : 'Zorro');
This enhancement is available with a compile-time PTF in the first half of the year 2017.
This enhancement is also available in 7.2 with a compile-time PTF.
- ALIGN(*FULL) to define the length of a data structure as a multiple of its alignment
-
When *FULL is specified for the ALIGN keyword,
the length of the data structure is a multiple of the alignment size.
Without *FULL, the length of the data structure is determined by highest end position of the subfields.
Specify the *FULL parameter when an aligned data structure is passed as a parameter to a function or API,
or when you use %SIZE to determine the distance between the elements in an array of aligned data structures.
For example, the following two data structures have a float subfield followed by a character subfield with length 1. The alignment size for both data structures is 8. The size of data structure DS_ALIGN_FULL is 16, while the size of data structure DS_ALIGN is 9.
See ALIGN{(*FULL)}.DCL-DS ds_align_full ALIGN(*FULL) QUALIFIED; sub1 FLOAT(8); sub2 CHAR(1); END-DS; DCL-DS ds_align ALIGN QUALIFIED; sub1 FLOAT(8); sub2 CHAR(1); END-DS;
This enhancement is available with a compile-time PTF in the first half of the year 2017.
This enhancement is also available in 7.2 with a compile-time PTF.
- ON-EXIT section
-
The ON-EXIT section runs every time that a procedure ends, whether the
procedure ends normally or abnormally.
In the following example, the procedure allocates heap storage. The code that follows the ON-EXIT operation is always run, so the heap storage is always deallocated. The ON-EXIT section is run whether the procedure ends suddenly due to an unhandled exception, or the procedure is canceled due to the job ending, or the procedure returns normally due to reaching the end of the main part of the procedure or due to reaching a RETURN operation.
dcl-proc myproc; p = %alloc(100); ... on-exit; dealloc(n) p; end-proc;
This enhancement is available with a compile-time PTF in the last half of the year 2016.
This enhancement is also available in 7.2 with a compile-time PTF.
- New parameter TGTCCSID for CRTBNDRPG and CRTRPGMOD to support compiling from Unicode source
-
The ILE RPG compiler normally reads the source files for a compile in the CCSID of the primary source file.
Since the compiler supports reading the source only in an EBCDIC CCSID, this means that the compile fails
when the primary source file has a Unicode CCSID such as UTF-8 or UTF-16.
The TGTCCSID parameter for the CRTBNDRPG and CRTRPGMOD allows the RPG programmer to specify the CCSID with which the compiler reads the source files for the compile. Specify TGTCCSID(*JOB) or specify a specific EBCDIC CCSID such as TGTCCSID(37) or TGTCCSID(5035).
The default is TGTCCSID(*SRC).
This enhancement is available with compile-time PTFs in the last half of the year 2016.
This enhancement is also available in 7.1 and 7.2 with compile-time PTFs.
