When you link to, or call, another program from an RSP, you must use a command format that allows the program to return to the RSP if you want the called program to share the same pipes. If the program does not return control to the RSP (for example, with an XCTL), CICS makes a copy of the SPAREA for the called program instead of pointing to the original SPAREA, the results of which are unpredictable.
To avoid this, use one of the following commands to link to another program: CICS LINK
programname
CALL programname
