EXEC CICS XCTL vs EXEC CICS LINK commands in CICS programming
EXEC CICS XCTL and EXEC CICS LINK are two important commands in CICS programming that are used for program control and communication. Here is the difference between them:
EXEC CICS XCTL Command:
The EXEC CICS XCTL command transfers control from the calling program to the target program without returning back to the calling program. It is used for program switching and is a high-level control command in CICS.
EXEC CICS LINK Command:
The EXEC CICS LINK command transfers control from the calling program to the target program and then returns control back to the calling program after the target program completes its execution. It is used for program communication and data exchange between programs.
Overall, the main difference between EXEC CICS XCTL and EXEC CICS LINK commands is that XCTL does not return control back to the calling program, while LINK does.
Both commands have their specific use cases in CICS programming, and understanding when to use each command is important for efficient program control and communication.
