The name of the DDM module is derived from the combination of
the name of the DIM and a
CICS®
VT exit program called VIDDDMEX. If the DIM name
is 7 characters or less, the default VIDDDMEX module supplied in
VID.SVIDLODE adds the character '#' to the end of the DIM name. The source and
assemble/link JCL for the default VIDDDMEX module is supplied in
my.SVIDCNFG.custom member VIDGDMEX. You can modify the
exit to produce a DDM name that is valid in your environment.
