OWN EXCEPTION NOT HANDLED

OWN EXCEPTION NOT HANDLED

[rashmi]

Dear reader

Inside a function I defined an exception of my own that is equivalent
to an exception of  constraint- error type. I have also created the
associated exception handler as shown next:
_________________
    :
if RE_ScDSGA.IN_RanSeq <  0   then raise EX_RsqIvd; end if;
if RE_ScDSGA.IN_RanSeq >  1   then raise EX_RsqIvd; end if;
    :
    :
exception
    when EX_RsqIvd => put_line("EXCEPTION: Invalid key INPUT for random
seq");
return RE_ScDSGA;
    :
___________________

There were no compiler errors or warnings. Now when a value of 2 was
supplied for the field variable IN_RanSeq, a constraint error would be
expected. But instead of handling this constraint error as I have
defined above, Ada handled it on its own by raising Constraint_Error.

My question is how do I get Ada to handle the constraint error from my
own handler rather than from the handler of its own?

We need to see the full code to be able to answer this;
Constraint_Error must be raised on some line you are not showing.

Try:

I just discovered that the exception's message was output in the file
specified by set_output(...). So I believe the problem is resolved for
now. Thanks for the suggestions anyway.
