Usage notes
Note: The IFCSA call is still provided for purposes of upward compatibility, but it no longer performs any function.
Use the IFCSA call only for an IFAM2 host language job with CICS. IFCSA is valid for use Model 204 releases before Version 3.1. For Model 204 Version 3.1 and later, the CSA control block is no longer needed and therefore, the IFCSA call is not required.
Coding examples
Before a program issues any operational Host Language Interface calls, the address of the CSA must be passed to the interface by using one of the following special calls in the host language program:
| COBOL: | CALL 'IFCSA' USING DFHCSADS |
|---|---|
| PL/1 Optimizer: | CALL IFCSA (DFHCSADS) |
| Assembler: | CALL IFCSA, ((13)),VL |
where the address is declared as:
