Re: Hmm, 3 ... (Re: Rexx numeric digits and scientific notation question

My experience of modern scripting languages, compared with classic Rexx, is that they all do something new more easily, but also I can't think of one that doesn't have an obvious pitfall (such as, for example, stumbling badly over certain byte values such as NUL in strings). Classic Rexx under

Re: Rexx numeric digits and scientific notation question

And there, I guess, is the answer to my question; no, I can safely stick with REXX for now, and leave Python alone, since Python is limited to OMVS. Maybe someday if I become a serious Unix jock. (The assertion that TSO isn't "modern" doesn't concern me.) I still meant what I said about being

Re: Rexx numeric digits and scientific notation question

I can tell you how it happened to me, at any rate. I was a long-time CLISTer, and then one day, back in the mid '80s it might have been, I ran across a warning from IBM that someday soon CLIST might go away and REXX would be the only supported language for system automation (or something like
