Charles Lester asked about combining traditional MVS steplib data sets with HFS directories in a STEPLIB DD, which would allow DLLs to come from either data sets or files.
This is a known requirement. The problem is that the result of STEPLIB processing is the output from BLDL, which can quickly be searched to find the program being requested. BLDL works directly against the concatenated DD statements in the STEPLIB. If Contents Supervisor (CSV) were to allow the intermingling of data sets and directories, it would require a significant rewriting of the CSV component. When a mix of data sets and directories are present, it would require the STEPLIB DD to be disected to determine if there were any PATH= specifications. Then it would require an independent search of each data set or directory to locate the module. Performance would be impacted. Since USS propagates STEPLIBs on fork, spawn and exec, it would also impact this USS code. There are also potentially customer and vendor code that poke around the TIOT and other control blocks when examining the STEPLIB. At the present time, we are not considering implementing this support. It would likely require a SHARE requirement with high interest to get us to look at it again.
