Odd. I just tried the same code snippet and it worked fine.
You might try putting a space before and after your = signs. I don't
know if that makes a difference, but it won't hurt.

This is wrong syntax; Street is not a scalar variable,
I guess I didn't quite use the original code. I made the mistake of
typing what it should have been instead of what it was:
#!/usr/bin/perl
$street=Wright;
print $street\n;
$street=Washington;
It's amazing what a dollar sign and a change of case can do.

This is wrong syntax; Street is not a scalar variable, while $street would
be.
print $street\n;
$street is undef here, you didn't assign anything to the $street
How do i Assign'Wright to the scalar how do i do
that?And how do i change a value of $street to
'Washington'
How do i print $street on it own line just like hello
world?

if you
use strict;
then you'll need to declare it with my. If you don't (and you should
think about that decision again) then you can leave off the my.
my $variable = somevalue;
$ means it's a scalar variable
@ is for arrays
% is for hashes

Hi,
Scalar is differenet distinctly from list.In perl both array and hash belong to
list,while common variable belong to scalar.When you say,
my $varA;
our $varB;
local $varC;
You get the perl variable and they're scalar.
Hope I'm correct.
