Can the DSN_XXX entry in the DBSIDPR customization use a symbolic variable?

For example, we have LPAR-specific files defined for the CXX:


We would like to use only one DBSIDPR, and code the DSN_XXX entry like this:


Can we do this so that we only have one CUSLIB and one DBSIDPR module?


The DBSIDPR macro does not support the use of symbolic variables in these values, as the value is used during the operation of the Multi-User Facility (called MUF) to create the file names, and it is not available to be modified from the JCL or other commands.

Also, you cannot share the CUSLIB file - in fact, you really cannot share any file with CUS* as the final qualifier in the name, as the information in this loadlib is customized for each MUF. Therefore, you need a separate CUSLIB for each MUF, and each MUF needs to have a unique name.
