The programmed symbols (PS) adjunct lets you specify that the special characters and symbols defined in a given symbol set apply for the field associated with the PS adjunct in the application data structure. You can define your own symbol sets using the Image Symbol Editor, as described in the GDDM Using the Image Symbol Editor book. You can also use the predefined symbol sets supplied by IBM.

Your application program can use characters from a particular symbol set only if that symbol set is loaded into a PS store in the device. A symbol set can be loaded when defining a mapgroup containing maps that use symbol sets. You can specify that the symbol sets are to be loaded automatically by GDDM when a MSPCRT request naming the mapgroup is issued; for more information, see the GDDM Interactive Map Definition book. Symbol sets loaded in this way are available to the application program for the life of the page.

The required symbol set is identified by the PS code (or PSID), which is a single-character identifier in the range X'41' through X'DF', designated by you or your installation. The PS code is designated when the mapgroup is defined, if GDDM is to handle symbol-set loading, or during the loading operation, if your application program or your installation is handling symbol-set loading directly.
