Sure it will - you just have to compile whatever function you need to trap in
with the /V or /W switch. Another example of this is
capturing printer errors with /X resumeability (New word! :-
) ). I can place ON ERROR GOTO code in the main module
with a trap routine that includes RESUME to enable
continuation after a printer error, place actual print
routine in a SUB module in a seperate .BAS file, compile
BOTH with /X, and when an error occurrs in the SUB,
trapping will jump to the error routine in the main .BAS,
and then RESUME will jump back into the SUB where it left
off. If I compiled the SUB without /X, then a RESUME would
continue at the point of the CALL to the SUB program in the
main .BAS. This is exactly the same with /V and /W.
