ADDRESS Environment Return Codes

CA-GSS treats return codes differently from TSO/E REXX. Under TSO/E REXX, the return code from the command is placed in a parameter passed to the routine, and the return code from the host environment (which may be set up to process multiple commands) is returned in Register 15. The value in the parameter word is used to set the RC special variable, and the value Register 15 is used to control continued execution of the EXEC.

Under CA‑GSS, the following convention is used:

• If Register 15 is zero, the RC special variable is set from the parameter list value.
• If Register 15 is not zero and the parameter list value is zero, the RC special variable is set from Register 15.
• If both Register 15 and the parameter list contain non-zero values, the parameter list value takes precedence.
