I got your problem.
Pass the parameters like below,
&replace_txt('\$a', '$b');
It will work fine.
In this line, $line =~ s/$old/$new/g;
$old should have \$a, in order to match a variable name.
If u pass '$a' alone - &replace_txt('$a', '$b');
$old will have $a and it will search for the value of $a and not actual $a.
Hope u will get this.
Thanks,
Suresh
