DMMEDM reads record 3 and 4 from
the dump file into the buffers called
item3 and item4. These records
contain the storage protection keys.
Read the remainder of the dump file,
a page at a time, and place them in
the print buffer.
3 Construct the print iine, piacing the
storage keys with the associated
hexadecimal storage contents.
(Printing of identical lines is
su pp ressed.)
4 Print the dump by branching and
linking to the PNTPAGE routine. If ERASE is specified, erase it and
