Syntax
DEBUG;
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;
