Hello, I would like to know if the following is possible in a perl regular expression:
s/ABC{$a}/$b/g;

so long as I can guarantee that $a will always evaluate to an integer. The Perl interpreter does not complain when it encounters this, but the substitution does not appear work. I tried putting the whole thing in an eval block, but no success. If anybody can think of another way to accomplish this, I would be appreciative. Thank you
