>Is there a way to use the Lightspeed C debugger to debug custom LDEFs?

	I usually implement custom defprocs by creating a dummy defproc
resource that's only six bytes long, containing $4EF9 0000 0000, and at
program startup, I patch the last four bytes to point at my custom defproc
which is implemented as a procedure in my program.

	It's wise to put the defproc in a segment which will not move
or be purged, e.g.,the main segment.

	It's a good way to debug defprocs...
