Description
The ccode function retrieves the two bit condition code for the calling
process. A condition code is a process-specific value that provides
information about the completion status of system intrinsic functions
calls. Many intrinsics use the condition code to signal success,
warning, or failure. From the condition code value, you can learn some
basic information about what happened during execution of the intrinsic.
