I haven't used LE COBOL DEBUG, but in other debuggers what I'd is compile the calling program and subprogram for debugging, set the breakpoint in the calling program at the call location you're interested in, then let 'er rip. When it hits the breakpoint, step into the call.

My problem is that the driving code (which I am forced to use by the structure of the application) unfortunately calls the subroutine from multiple places, but the error I am tracking down only occurs from a call at one of those several call locations. What I hoped to do is to turn OFF the effect of WITH DEBUGGING MODE until the driving code gets to the one call location of interest, then turn the WITH DEBUGGING MODE ON again for just that one call location and turn it OFF again after that one call location completes the call. I am guessing this isn't possible, so I will just have to ignore the chaff and look only for the wheat.

Debugging lines that start with D are activiated by a COBOL clause: WITH DEBUGGING MODE, on the PROGRAM-ID statement. You could have that clause in only the program you are interested in. The whole application would have to to be run with the LE DEBUG option, but only programs that have WITH DEBUGGING MODE will activate the debugging lines.
