How to Use Conditional Debug_Out & Trace_Out Debugging Strings (153386)

This article was previously published under Q153386

To avoid adding extra code to your source just to test or branch around debug message strings, you can use the built-in conditional macros in addition to the more plain Trace_Out and Debug_Out. An inspection of the DEBUG.H or DEBUG.INC files shows the following syntax:

Trace_Out## or Debug_Out## where ## is one of the following flags/conditions:

S, C, A, AE, B, BE, E, Z, G, GE, L, LE, O,
NS,NC,NA,NAE,NB,NBE,NE,NZ,NG,NGE,NL,NLE,NO,
EAXZ,EAXNZ,ECXZ,ECXNZ

example: Trace_OutC "carry set - function call failed with AX = #AX"
