Re: New Rexx Question
You can also use UNTIL to simulate an IF block from which you can LEAVE. Otherwise it's difficult, or at least a little complicated. Like this: /* hard way */ if condition1 then do if \subcondition2 then do v1=calculation(a,b) v2=calculation(c,d) if v15 then do /* process your logic */ end end end You can't make it a pure CASE statement because of the calculations you have to perform inside the block. But you can do this: /* I prefer: */ do until true /* in other words, do once */ if \condition1 then leave if subconfition2 then leave v1=calculation(a,b) v2=calculation(c,d) if \(v15) then leave /* process your logic */ end I think this is simpler to look at. --- Bob Bridges, robhbrid...@gmail.com, cell 336 382-7313 /* God's never been disappointed in me, because he never had any illusions about me. -Clay McLean */ -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Paul Gilmartin Sent: Thursday, February 27, 2020 17:29 > UNTIL has the minor simplification over WHILE in that it's not evaluated until the end, so its variables needn't be preset.

Re: New Rexx Question
I love the ITERATE statement, to the extent that I've insisted on its availability in other languages. In VBA, for instance, like this: For each oxct in xcts If Not Exists(Collection, xct.Key) Then Goto IterateXct ...blah, blah, blah... IterateXct: Next oxct Very handy to prevent long indented If blocks; multiple ITERATES are much easier to debug. --- Bob Bridges, robhbrid...@gmail.com, cell 336 382-7313 /* Three people may keep a secret, if two of them are dead. -Poor Richard */ -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Gibney, Dave Sent: Thursday, February 27, 2020 17:40 On further contemplation, I also wanted to use iterate, so I surrounded the whole thing with i = 1 do forever do i = i to stem.0 /* Processing with conditional additions and iterates */ end if i > stem.0 leave end -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Re: New Rexx Question
Dave, you are correct that stem.0 is resolved at the start. If you think about it, if it were dynamic, then your code would be a never-ending loop. The key here is to know how many items you want to add, and where in the stem list you want to add them. Give us a little more detail, and we can help you out.

Re: New Rexx Question
I think thats true. You should be able to code do while i <= stem.0 to do what you want. You will have to set initial value for i and increment it in your loop.
