This example invokes the LMQUERY service to provide information
about the ISPF library associated with the data ID in variable DDVAR.
The data ID is created by using the LMINIT service with an ISPF library
name. They use these variables:
- PRJV
- Highest-level qualifier of the libraries.
- GRP1V, GRP2V, GRP3V, and GRP4V
- Second-level qualifiers of the libraries.
- TYPEV
- Third-level qualifier of the libraries.
