That's the idea but the problem is is that @ row seems to transalet itself
into 'print userrname; and print

string '$password'

Which is actually "HI whatevermyvariablecontains"
That's the dilemma.

I guess we all got lost in what's the actuall variable name, what's
to be interpolated when ad so forth. Let's try s

Exactly! The problem is is that $var conatins '$foo' but it sees it as having 'bar'.
Thanks for helping me clarify.

I believe that what he's after is a RE that will match the name of a
variable proceded by a dollar sign.
I.E., given this:
$foo = "bar";
if ( $var =~ // ) { print "true" }
He wants the expression to evaluate true if $var contains the string
$foo; that is, the character '$' followed by 'f' 'o'
Hi Dan
Not clear what your problem is. This works, is it representative?
my @row = ('print $user;', 'print $password;' );
foreach (@row)
{
print $_;
print ( /\$password/ ? "\t# Invalid" : "\t# OK");
print "\n";
}
Cheers,

"Dan Muey" <[EMAIL PROTECTE
for the 'value' of $variable?
I need it to find the actual string '$variable' not what $variable
contains.
Any other ideas?

Don't escape the $ in the RE.

Why not just hard code that in you ask? Because this needs to be very very flexible
