Re: for loop help

Well, you could certainly do what you want to do using eval, but fundamentally it looks like you have the wrong data structure for the job.

Rather than having a bunch of scalars you might consider using an array, or a hash, or most likely a hash of arrays. Since I'm not certain of the relative significance of the scalar letters (a,b,c) and the apparent index numbers (1,2,3) it is difficult to make a specific recommendation.

I'm sure a fast-coder will follow-up with some magical sample code shortly.

don't do that ;-) `use strict; my $a1 = 0; my $a2 = 1; my $a3 = 4; my $b1 = 8; my $b2 = 2; my $b3 = 9; my $c1 = 1; my $c2 = 4; my $c3 = 7; for (my $i=1; $i<=3; $i++) { print eval "\${a$i} . \${c$i}. \${c$i}" }` [download]	[reply] [d/l]

use strict;
my $a1 = 0; my $a2 = 1; my $a3 = 4;
my $b1 = 8; my $b2 = 2; my $b3 = 9;
my $c1 = 1; my $c2 = 4; my $c3 = 7;

for (my $i=1; $i<=3; $i++) { print eval "\${a$i} . \${c$i}. \${c$i}" }
