Using DBCS symbol sets

GDDM V3R2 Base Application Programming Reference
SC33-0868-02

For Kanji/Hangeul applications that have double-byte character string (DBCS) symbol sets installed, this type of symbol set can be used directly (by the application program loading the required symbol set and using the definition in the normal manner) or indirectly (by the application program indicating that it requires to use DBCS symbol sets). In the second case, if the GSCS call specifies character set 8 (DBCS) or if mixed (single-byte and double-byte) character strings are enabled (by specifying MIXSOSI=YES in GDDM's external defaults), GDDM recognizes DBCS characters and uses the first byte of the character to identify the symbol set to be loaded and the second byte to retrieve the symbol definition.

Applications access Simplified Chinese vector symbol sets by setting the DBCSDNM(ADMIK,ADMVC) external default.

GDDM's external defaults define whether mixed strings are enabled and indicate the maximum number of DBCS symbol sets of each type that are to be loaded concurrently. When this maximum number is reached, the least recently used symbol set is unloaded to allow the currently required symbol set to be loaded. For details of the external defaults, see "External defaults" in topic 18.0.

For graphics, DBCS symbol sets are available for mode-2 and mode-3 only.
