Re: Using constants. What am I doing wrong?

Others have told you why you get the result you get; here's a couple of ways to get around it:

# this:
BEGIN { use vars '$Base'; $Base = 'mybase'; }
use constant BASE => $Base;

# or this:
my $Base = 'mybase';
sub BASE () { $Base }

The correct solution you're looking for is: `my $Base; BEGIN { $Base = 'mybase' } use constant BASE => $Base;` [download] Being right, does not endow the right to be rude; politeness costs nothing. Being unknowing, is not the same as being stupid. Expressing a contrary opinion, whether to the individual or the group, is more often a sign of deeper thought than of cantankerous belligerence. Do not mistake your goals as the only goals; your opinion as the only opinion; your confidence as correctness. Saying you know better is not the same as explaining you know better.	[reply] [d/l]

Strange. I could have sworn I'd tried that solution first, but found it to not work. Just tried it again before I was going to post saying 'that does not work', but all of a sudden it works. Strange world :)	[reply]

The second one does not make a constant `perl -le'my $BASE="are belong to us"; sub BASE () { $BASE }; $BASE="fred"; print "all your base ", BASE' all your base fred` [download] Cheers, R. Pereant, qui ante nos nostra dixerunt!	[reply] [d/l]
