my @chars = unpack
("A1" x length($password),$password);

if ($chars[0] =~ /^\D/) {
print "Your new string is:\t",@chars,"\n";

print "string starts with number, now
converting\n",

substr($chars[0],0,1) =~
s/\Q{$chars[0]}/{chr($chars[0]}\E/;
print @chars;
}


I will try to use the /e modifier as such:

s/(\$\w+)/$1/e;

An explanation is below:
/e
Righthand side of a s/// is code to eval

/ee
Righthand side of a s/// is a string to eval, then
run as code, and its return value eval'led again.
