> I would imagine their other JCL checker product probably has the same issue
I was once acquired by ASG and worked there for about four years, but I have no special knowledge of logic of the JCL check products. That said, the products were acquired from competing companies and had different code bases, so the internal processing might be quite different, and a given bug might be specific to only one of them.

There are actually several PRO/JCL problems that we have open with ASG currently, related to GDG processing with tape and also tape processing with disp=MOD and disk processing with DISP=MOD. I think we have 4 altogether. Of all the problems, the only one they fixed is that the PROCLIB concatenation was not being dynamically located under z/OS 2.3. (the easiest one for us to code around by already defining the libraries explicitly in the parms). I would imagine their other JCL checker product probably has the same issue but I don't know for sure. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
