good use of variables

steph_bow has asked for the wisdom of the Perl Monks concerning the following question:

Hello, I would like to use a variable such as below, and the name of this variable depends on another variable.

Is that allowed or is there any better way ? Thanks

my @TARGET =(0..50);
  foreach $target(@TARGET){
  my $M4_${target};
  }

See Why it's stupid to `use a variable as a variable name`. The short version is, you don't want to do that, and most likely want to use a hash instead.	[reply]

Heh ... couldn't help but notice that Corion's advice (which is sound) is only a couple of typos away: `my @TARGET =(0..50); foreach $target(@TARGET){ $M4_{$target}; }` [download] Cheers, Rob	[reply] [d/l]

The `my` is still required, but stuck in front of `$target`. ;) DWIM is Perl's answer to Gödel	[reply] [d/l] [select]
