Can anyone help please I am converting an old RPG program

The program uses a GOTO and TAG to exit from the middle of a

And needs to bypass much more code after the highest ENDIF,
this is all dependent on a Flag returned from an external program.

Yuck. You cannot code a GOTO in free-format. If you cannot devise a structured solution then end free-format, code the GOTO, and start free-format again.


Do similar around the TAG.

Ugly? Yes, but then so is the code you describe so pick the lesser of the two evils.

There are other contorted solutions such as a fake loop, a flag, and LEAVE to provide a "structured" solution. These tend to be just as ugly.

I'd suggest breaking the code up into procedures to remove the code from the main body. Then wrap the procedures in IF tests conditioned on the flag returned from the external program. You'll end up with cleaner code as a result.
