Re^3: checking values of variables

[Anonymous Monk]

this question garnered a fair amount of interest and I appreciate the replies.

In what way (what did you decide)?

[Anonymous Monk]

I decided to stay with what I have (because the scalar variables are used all over the program and I didn't want to do a great deal of editing). However, next time I have this situation I will most likely use:

for (qw / server database user password ... initversion /) {
     help() and last unless (defined $cfg->params($_) and $cfg->params
+($_));

and use $cfg->params(server) instead of $server Thanks to all (Perl Monks is fantastic!)

however, this approach does not allow

$mail_host          = $cfg->param('mail_host') || '[e-mail]';
$support_addr       = $cfg->param('support_addr') || '[e-mail]'
+;

default values.
