This service is used only with CALL ISPLINK or CALL ISPLNK calls.

The GRERROR service returns to the caller the address of the GDDM® error record and the address of the GDDM call format descriptor module.

This service allows the dialog developer to examine the error record provided by GDDM from GDDM function calls. Since the dialog uses the same application anchor block (AAB) as ISPF and cannot use the FSEXIT function, this information would otherwise be unavailable. See the GDDM Base Application Programming Guide for information about the GDDM error record and the GDDM Base Application Programming Reference for information about the call format descriptor module.
