Hi Monks,

I hope someone can help me with the following question. I have
the following construction in a program I am writing

#!/usr/bin/perl -w

use strict;

BEGIN{push @INC,"$ENV{'SM'}/../bin";};

require 'errors.pm';

[download]

Which ofcourse is quite tricky, because the $SM evironment-string
might be non-existent.
So ... being unfamiliar with 'BEGIN' I tried something similar to
the following:

#!/usr/bin/perl -w

my $Err;
BEGIN{$Err=1 unless $ENV{'SM'}; push @INC,"$ENV{'SM'}/../bin";};
die "Environment string: \$SM not set\n" if $Err;

require 'errors.pm';

[download]

Which ofcourse was quite silly, because the BEGIN-block will be
run first. After that I tried a couple of other things, which
were, by the way, even more silly (other words come to mind ;-)
So here's the question ... (......) ... What variables (like
@INC are exported from the BEGIN-block to the main program,
in order to pass information to it, like in the example above

Your help is highly appreciated,

Thanks, Leon
