Dear Monks,
I have an array holding codes like ABC, DEF, GHT etc. I want to look through a text file and replace any matches to the array codes with the position that code holds in the array.

ie. so if my codes are $code[0]=ABC and $code[1]=DEF and the file contains the text ABC and DEF it gets replaced with the numbers 0 and 1 instead.

I have tried this: 

while(<DATA>)
{
for($a=0;$a scalar@codes;$a++)
    {
    s/$codes[$a]/$a/;
    }
}
print $_;

Which doesn't work. I'm probably trying something really dumb, but I hoped the substitution might be able to work like that. Any ideas on better methods ?

Thanks a lot,

anon
