John (et al): There is a tool from a vendor I work with that not only addresses the need to automatically modify JCL at any point of access, but also can call this same automatic modification facility from a tool that interfaces with the scheduler software (virtually any vendor tool you can think of) and it allows on demand or on request jobs to be managed through the scheduler, but independent of the Prod Cont Department staff.

This will tie you rigidly to this product and will cost you a lot of ork if you decide to convert to another scheduler in the future. Having learned rom Syncsort and PDSMAN whose features were not compatible with the orresponding IBM products, we only use a few of the % features of Control-M and nly in a very controlled group of jobs. This also answers your question partly. I only want to use a few AutoEdit variables so that we can avoid having to aintain test and prod versions of the same JCL. After struggling for many onths, I have finally got my client to adopt and implement standards for test ataset names and libraries. So it is possible to switch JCL from running gainst PROD resources to alternative TEST resources by passing an Environment D and letting all the DSN's reference symbols that are derived from the EnvID. eyond this, TEST JCL needs to differ from PROD in only a few other respects: a) Initial character of the JOB name, (b) Account Field, (c) JOBCLASS, and (d) SER on the JOB card. I had hoped to make these four Control-M symbols, plus he previously mentioned %%ENVID. So only the first few lines of the JCL member would be affected. In the event hat my client changes their mind about Control-M, I can easily refactor the JCL o whatever the new requirement demands. I have developed a JCL parsing tool hat loads JCL statement text into a SQL database. Plus other tools to identify atterns for change and generate PANVALET ++UPDATE statements to make the hanges. So doing what I plan won't tie me to the product and it wouldn't cost hat much to convert to something else. However, doing what I plan will be a complication for developers who want to ubmit outside of Control-M. I was certain that someone else on the list would ave addressed this need. But it looks like I will need to follow John M's dvice and roll my own. Which is going to be hard since I haven't done REXX in 0 years. Also, the solution proposed by Aussie Anthony Thompson won't work for me, since am pretty sure that jobs ordered using CTMAPI will still cost against our icense count. Thanks to all who have responded to this inquiry.
