The GDF file-conversion utility

GDDM V3R2 Base Application Programming Reference
SC33-0868-02

The conversion utility is distributed as a module called ADMUPCV. This utility converts ADMGDF objects into PIF files, or converts PIF files from the work station into ADMGDF objects.

The conversion utility also converts files (created by applications from GSGET calls and often named GDDM Version 1 Release 2 and 3 GDF files) into ADMGDF files; see "Saving GDF orders" in topic 10.2.

Figure 18 shows the flow of events.

When the IND$FILE EXEC executes, the ADMUPCV command is invoked to run the conversion utility if the ADMGDF option has been specified in a SEND or RECEIVE command.
