Variable in variable name

Is there a way to do something like this:

$a = "z";
$b$a = 10;
print "$bz\n"; # which would print 10

Thanks!

Hi

$a = "z";
[red]eval "\[/red]$b$a = 10[red]"[/red];
print "$bz\n";

Cool! That worked! I also found another solution:

$a = "z";
${b.$a} = 10;
print "$bz\n"; # which would print 10

Thanks for the quick response!

And hopefully you don't actually do that in real code. What you probably should do is use a hash.

$a = "z";
$hash{$a} = 10;
print "$hash{'z'}\n"; # which would print 10

Agreed, Kevin. You may or may not remember from awhile back, but I've been working on a code converter (on and off for awhile now)...and I don't have the luxury of doing everything the "right" way. I'll probably look into this hash option, however, because I agree that that is the proper/best way of doing it.

Thanks all!
