Issue a synchronization request on an APPC basic conversation (assembler-language and C programs only).
Description
GDS ISSUE CONFIRMATION issues a synchronization request in response to a GDS SEND CONFIRM issued by a partner transaction.
The return code is given in RETCODE (see Table 1). For a list of return code values, see the Return codes for APPC basic conversations . EXEC CICS® conditions are never raised on GDS commands.
Options
In general, the arguments can be replaced by absolute or relocatable assembler-language expressions.
