This may be old hat, but I just started reading this group.
 
I need to get my programs, written in Tp5.5, to execute a procedure
or flag a variable/address when a run-time error occurs, instead
of exiting the program with an error. I know how to do this with
dos and graphics errors.

eg: if a user enters 2 real numbers and  the program multiplies them
together, and if the result is too large for even a real number to
handle, the program will quit with an error.
Instead I would like to check (via a variable or address) if the
result was ok, before proceeding, else it will take steps to
deal with the problem.

Even my instructor ('Turbo Tom') can figure out how to do this.

Thanks
