If I understand the question correctly, you use: `substr($string,0,2,"");` [download] Which removes what you want, but also returns it, and not the remaining string. Instead, try using substr as a lvalue: `substr($string,0,2)="";` [download]	[reply] [d/l] [select]

Just to add to this answer, both of those solutions will alter the original string. If you do not want the original string to be altered, then make a copy first...	[reply]

That's easily done with substitution: `$string =~ s/\\'\\'//;` [download] Or more elegantly... `$string =~ s/\Q\'\'\E//;` [download] ...where \Q and \E eliminate the need to escape the backslashes. Actually, for such a small substring, \Q and \E may just look like too much line noise. This will remove the first occurrence. If there are multiple, you have to modify with /g.

I am puzzled by the question. If `$x` is the string 'abcdefg', then `my $tail = substr $x, 2;` [download] will assign to `$tail` the string 'cdefg', which sounds like what you want. the lowliest monk	[reply] [d/l] [select]
