Return Codes from Host Commands

When a host command executes, OPS/REXX sets the variable RC to a value indicating whether the command executed without errors or failures. In general, errors are problems that the calling program can probably recover from, and failures are unrecoverable errors. When an abend occurs as a host command executes, OPS/REXX considers the abend to be a failure.

• If the value of RC is zero, the host command detected no error or failure.
• If RC has a positive value, the host command detected an error.
• If the RC value is negative, the host command detected a failure.
