yeah, usually pointless, mainly just a habit I got into because every statement resets the RC value, and if you don't put the RC check right after the critical statement that needs to be checked, you're checking the wrong RC. putting statements in-between the RC that needs to be checked and the code that checks it, is one of those things that shouldn't happen, but somehow it does, especially when working with ISPF commands.
the habit also ensures that I'm checking the RC's for the allocates/read/writes/calls etc. If one my programs has a problem with a less than obvious solution, that's one the first things I do is look for the "lc = RC" statements (and corresponding action DO) to make sure I'm checking the critical things that need checking in order for the program to work the way I designed it. Cosmetically, it helps them stand out better. --- On Sat, 7/30/11, Paul Gilmartin <paulgboul...@aim.com> wrote: > From: Paul Gilmartin <paulgboul...@aim.com> > Subject: Re: REXX code on JES2 > To: IBM-MAIN@bama.ua.edu > Date: Saturday, July 30, 2011, 8:44 AM > On Fri, 29 Jul 2011 15:52:45 -0700, > Cris Hernandez #9 wrote: > > > >what I usually do with my rexx programs is set one > variable (maxcc =0) at the beginning, and then set every > critical RC to lc, and then check "IF lc > maxcc THEN > maxcc = lc". only if the RC indicates a critical > failure do I use "SIGNAL The#end" to "EXIT maxcc". > > > I've done that.
