DEBUG Intrinsic

Discussion

The DEBUG intrinsic calls Debug from an interactive program. The intrinsic call acts as a hard-coded breakpoint. Execution of the calling program is halted, and the Debug prompt is displayed.

If the call is made from a batch program, it is ignored.

Refer to the MPE/iX Intrinsics Reference Manual for additional discussion of this intrinsic.

Condition Codes

This intrinsic does not return meaningful condition code values.

Example

The following example is a code fragment from a Pascal program. It declares DEBUG as an intrinsic and then calls it.

   PROCEDURE call_debug;
 
      procedure debug; intrinsic;
 
   BEGIN
      debug;
   END;
