Leslie, The stack (queue, if you prefer) provided by ooRexx attempts to mimic the behavior of the inherit stack provided by mainframe z/VM, also known as CP/CMS, where Rexx was developed by Mike Cowlishaw.
There, the stack is *ahead* of the console input buffer (command line input) by the design of CP (which provides virtualization [we'll ignore PR/SM for purposes of this discussion]) and CMS (one of many Os's that can be used). I'm a VM dinosaur and don't use Linux or even much of Windows from ooRexx, except for exactly what I need to get the job done. So, with those caveats, here's what I think. Hopefully, real experts will refine/correct this as needed. I've done some exploring with Google for 'yad Linux' and found that yad gets it input from STDIN, just as one would expect. If the stack works as I expect it should, after you've done the Parse Pull and modified *all* the lines you can then QUEUE each one before invoking yad. You might need some kind of termination marker as the last line. Perhaps a null line? I notice that yad is on SourceForge, so you should be able to find some documentation about it. There are *lots* of examples there, but none that I could find using ooRexx. :-( Please keep us updated on your progress. Les On 9/12/2016 11:35 PM, J.
