Hi,

I'm trying to escape a variable with the \x special character, so it will be printed as a hex character. I only manage to do this when I statically define variable, for example: 

my $foo = "\x4D";

print "$bla";

M

But when i try to add the \x to an already existing variable, I always get an "Illegal hexadecimal digit '$' ignored" error message: 

my $foo = "4D";
my $bar = "\x4D";

print $bar . "\n";

Illegal hexadecimal digit '$' ignored at roman.pl line 10.
4D.

What am I doing wrong here, and is it solvable?

Thanks,

Eran
