Re: Leave outside of DO group???

These lines of code:

Are nothing near to:
Do
ChkObj QSTRUPEX1 *Pgm /* Check for exit program. */
MonMsg CPF9800 EXEC(Leave) /* Not there or Not Authorized */
Call QSTRUPEX1 /* Run it. */
MonMsg CPF0000
EndDo

The former "is of course effectively the same as the LEAVE" *intends* in the latter. In my message [from which that first code snippet was taken], I was replying to the failed intent, not replying to the potential capability of the LEAVE had the program actually compiled successfully. After posting, I thought to add that word "intends", to clarify that point, but I figured it was obvious enough. Apparently not :-(

The first example never breaks out of the loop. <<SNIP>>

That claim ignores the facts that the original code, the latter of the above compared snippets, is a non-iterative Do-group, and that the code is expressing a desire\intention rather than reality; i.e. the LEAVE is not allowed, as coded, effecting a compile error.

To be clear, there was no *loop* to break out of, in the original code. The Do-group shown was a linear standalone Do-group, not an iterative Do-group, nor was that standalone Do-group located inside an iterative Do-group, else the original code would have compiled without any error. So as I had written, the code snippets are the same, in effect; whereby the former is functional, and the latter was merely expressed as a desired non-functional *intended* effect.

At the LEAVE Statement I get this error:
* CPD0883 30 LEAVE command found outside of DO group. <<SNIP>>
