The TCTUALOC system initialization parameter specifies where terminal user areas (TCTUAs) are to be stored.
- TCTUALOC={BELOW|ANY}
- Valid values are as follows:
- BELOW
- The TCTUAs are stored in 24-bit storage (below the 16 MB line). If you require the terminal user areas to be in 24-bit storage, because you have application programs that are not capable of 31-bit addressing, specify this setting.
- ANY
- The TCTUAs are stored anywhere in virtual storage. CICS stores TCTUAs in 31-bit storage (above the 16 MB line) if possible. This setting is the default.
For more information about TCTUAs, see The TCTUA.
For details about defining terminals using RDO, see Model TERMINAL definitions in group DFHTERM.
