Each partition set definition contains a single
DFHPSD macro followed by one or more DFHPDI macros, and ending with a DFHPSD
TYPE=FINAL partition set definition macro.
“partnset” is a partition set name (1–6 characters).
Partitions are defined by coding the macros DFHPSD (partition set definition)
and DFHPDI (partition definition). Each partition definition must be part
of a partition set definition.
Operands
- ALTSCRN(lines,columns)
- specifies the size, in characters, of the usable area of the target
terminal. This is normally the same as the RDO TYPETERM option ALTSCREEN.
You use ALTSCRN to ensure that the viewports of partitions within a partition
set fit into the usable area of the screen.
- CHARSZE(vpels,hpels)
- specifies the size of the character cell to be reserved for each character
displayed in a partition. You specify the size as numbers of vertical picture
elements (vpels) and numbers of horizontal picture elements (hpels). You can
specify this operand on either the DFHPSD macro only, or on both the DFHPSD
and DFHPDI macros. The values specified in this operand become the defaults
for all partitions in the partition set. You can override this default for
individual partitions by coding CHARSZE in the DFHPDI macro.
- SUFFIX(user-suffix)
- specifies a 1-character user suffix for this version of the partition
set. It allows different versions of a partition set to be associated with
different terminals. When the partition set is to be loaded, CICS® looks for
a version whose suffix matches the RDO TYPETERM option ALTSUFFIX. If it cannot
find the correct partition set version, it loads a version with a default
suffix (M or L). If it cannot find a suffixed version either, it loads an
unsuffixed one. If it cannot find this, it abends with APCT.
