Problem with substitution

[denis60]

Hi!

Is it possible to substitute a variable containing special characters like $ and use it as a character and not like a variable ex:
$rwrd=substr("cic $ nil",1,6);
$data =~ s/$rwrd/+\n/;

Each time a $ appear the substitution fail.

Sorry my exemple was too simple.

$rwrd=substr($var,1,6);
$data =~ s/$rwrd/+\n/;

$var is variable and may have a $ or not. It get $var from each line of a file.

Ah!

#!/usr/bin/perl

$var = '$123';

$_ = 'string of $123 text';

s/[b][red]\Q[/red][/b]$var//;

print;

Yes it work with single quote, but the $rwrd variable come from a substr and i think the data in it is like
$rwrd = "$123" and it fail...Sorry.

like \Q$var\E
