2-3-2 Character String Memory Table
Character string memory table entries are internal memories of the PT for re-
cording character string data.
Since words can be allocated for character string memory table entries in the
host, the contents of words at the host can be displayed as character strings at
the PT via the character string memory table.
Character string memory table entries are assigned character string memory
table entry numbers so that they can be managed and designated individually.
