The data communication PCB(IOPCB) is automatically included
by the IMS at the beginning of the PSB for an MPP or BMP.
This default data communication PCB is used to insert O/P
messages to the originating terminal. ALTPCB is coded to
identify alternate destination for the O/P messages, say
printer.
/DIS PGM will tell whether its online or batch. If the pgm
is not found, it is purely batch. Otherwise its an MPP or
BMP.
