------------------ General-use programming interface -------------------
During its operation, GDDM uses many values that you can alter to
customize GDDM for your installation. These values are known as
user-default specifications (UDSs). GDDM uses five types of UDS:
- ADMMDFT
- The ADMMDFT statement defines an external default. External
defaults define a variety of system values, such as buffer
sizes, conventions for time and date expressions, the
national language of your installation, and the code page to
be used. Many of the external defaults are subsystem
dependent. Appendix A, "External defaults" in topic A.0
describes all of the external defaults. You will also find
them referred to as appropriate throughout this manual.
- ADMMNICK
- The ADMMNICK statement defines a nickname. The nickname is
a powerful mechanism for defining how devices are to be
used. Nicknames are used to specify processing options
(also known as "procopts") and device tokens to GDDM.
Nicknames are described in "Nickname user-default
specifications" in topic 3.9.
- ADMMEXIT
- The ADMMEXIT statement defines a user exit. User exits
allow a system program to trap specific events whenever an
application program uses a GDDM resource or a system
resource. For more information about user exits, see the
GDDM Base Application Programming Reference book.
- ADMMCLTB
- This UDS enables you to modify the color table used by GDDM
when applications generate PostScript output to ensure that
GDDM colors are represented accurately. It can also be used
to change the color table used by the ADMUGIF utility. Each
GDDM color number is defined in terms of RGB and CMYK
values.
For more information about using this UDS definition, see
"Specifying the color mapping using the ADMMCLTB UDS" in
topic 3.6.1.
- ADMMTYPF
- This UDS enables you to specify how applications that use
GDDM symbol sets and presentation-text fonts are to map
those symbol sets and fonts to typeface names when a
PostScript file is generated.
For more information about using this UDS definition, see
"Specifying symbol-set and font mapping using the ADMMTYPF
UDS" in topic 3.6.2.
This topic describes how to specify UDSs to GDDM.
