Call format descriptor module GDDM V3R2 Base Application Programming Reference SC33-0868-02 |
|
A GDDM call format descriptor module, which is independent of the subsystem under which GDDM is running, is provided with GDDM. The module contains information for each GDDM Call statement, describing the number of parameters required on the call, and the type of each parameter. The address of the call format descriptor module can be acquired by an application program by using the CALLINF external defaults option in a SPINIT call. The call format descriptor module is in three sections. The first section provides an address table locating the descriptors for call statements with a given first two characters. The second section (the call descriptor table) provides descriptors for all GDDM calls that have the same first two letters in their name. The third section (the parameter descriptor table) provides descriptors for the parameters for a specific call statement. Subtopics: |
