CLI0156 No context word parameter
The second parameter does not point to a context word.
The context word is used to store the address of the CLI2 working storage areas. This word is a fast path to the working storage areas. If the context word is zero, the working storage areas are found through a longer path and the address stored in the context word. This error indicates that the second parameter (the address of the context word) is missing or invalid.
Correct the error and resubmit the job.
