STEPLIB data sets
The STEPLIB summary contains all data sets in the STEPLIB concatenation in the order defined in the CICS® job.
To display STEPLIB data sets, select the STEPLIB option (C) on the Files path or enter fast path F.C from any panel.
The Attributes field shows the blocksize of each dataset. If the leading library in the concatenation is overridden with a larger blocksize, the Attribute field still shows the true blocksize rather than the blocksize currently used.
The additional segment in the STEPLIB file detail display shows all the MVS loaded modules in the CICS address space. The list of modules is loaded from all data sets in the concatenation sequence, not necessarily from the one you selected by zooming.
