Re^2: Getting Value from joining 2 variables

"$pax_$plus" simply creates a string. If $pax is "foo", and $plus is "100", then "$pax_$plus" creates the string "foo_100"

Not at all. It tries to look up the variable $pax_ (since an underscore is valid part of a variable name), and fails (and thus interpolates the empty string for $pax_).

use strict; use warnings; would have caught the problem, and can only be highly recommended to Noverast.

Perl 6 - second systems done right

Good catch! I frequently trip on that one and also `$sClass::Blah` when I mean `${sClass}::Blah`. Thanks.	[reply] [d/l] [select]
