Well, I have tried some things, but it doesn't recognize the errors I
introduced. For example, if a long REXX-command is divided over multiple
lines, there should be a , at the end of each line as a continuation
character. But when I leave the , away, the REXX-program still runs, until
it comes to that piece of code, where REXX generates a syntax error.
