 01 LIBRARY-ALLOC.
    05 LIBRARY-SHARE-STATUS             PIC X VALUE 'S'.
    05 LIBRARY-DATASET-NAME             PIC X(44)
                             VALUE 'YOUR.PREFIX.TBASE.MAINLIB'.

where:

LIBRARY-SHARE-STATUS (l byte) indicates how the allocated library is to be shared, and is equivalent to the DISP parameter in MVS JCL.
