Eval block not working

I have something along the line of:

# FILE1.pl
require "FILE2.pl";
eval { &function(); };
print "$@" if $@;
print "This never prints.
"

#FILE2.pl
sub function
{ die "A horrible death.
"; }

For some reason, I never get to the second print. I think the
first print isn`t happening either. The die seems to in fact, be
dieing, instead of getting trapped by eval as the book says.

Is there some magic trick I`m missing here? I`m using ActivePerl 5.8.

Eval block not working

Hi

You can try by removing the underscore before eval function i.e. eval {
&function(); }; not _eval….

and i suppose you have any other coding other than SubFunction in File2.pl
because if there is no process done in file2.pl the require will show error

see the $tmp in file2.pl

# FILE1.pl
require "FILE2.pl";
eval { &function(); };
print "$@" if $@;
print "This never prints.
"

#FILE2.pl
$tmp=1;
sub function
{ die "A horrible death.
"; }

Regards

Krishna

You already asked this. Do we have to endure the pain again?
