Very naughty. This is actually code which --undeservedly-- gives Perl a bad name. CountZero A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James	[reply]

... I also included: use strict; use warnings; Really? With `use strict` it should've stopped working `#!/usr/bin/perl use strict; use warnings; our $pax_1 = "foo"; my $plus = 1; my $name = "pax_$plus"; my $paxing = ${$name}; print "$paxing\n"; __END__ Can't use string ("pax_1") as a SCALAR ref while "strict refs" in use +at ./880063.pl line 8.` [download] unless you also disable `strict refs`, e.g. as follows `#!/usr/bin/perl use strict; use warnings; our $pax_1 = "foo"; my $plus = 1; my $name = "pax_$plus"; my $paxing; { no strict 'refs'; $paxing = ${$name}; } print "$paxing\n"; # "foo"` [download]	[reply] [d/l] [select]
