Not a problem.  Brand new to Perl and already using strict, you're off 
to the perfect start.  Welcome.

Re: Problem with compiling a script

Hi,
Qualify the variable's in your perl script, since the script uses 
strict(use strict). For Eg: declare $greeting as "my $greeting"
or comment "use strict" and that should work.

Dear All
I am trying to run the script below, but I always get the following 
error:

[EMAIL PROTECTED] scripts]$ secondperl
Global symbol "$greeting" requires explicit package name at 
/home/paulus/scripts/secondperl line 6.
Global symbol "$greeting" requires explicit package name at 
/home/paulus/scripts/secondperl line 7.
Execution of /home/paulus/scripts/secondperl aborted due to 
compilation errors.

The script is:
#!/usr/bin/perl
use warnings;
use strict;
$greeting = "World";
print "It matches\n" if "Hello World" =~ /$greeting/;
Any ideas?
Thanks in advance,
Paul

Easy enough.
The script is:
#!/usr/bin/perl
use warnings;
use strict;

Above, you are asking Perl to make you play by the Good Programmer 
rules.  One of those rules is, you  must declare a variable before using 
it.

$greeting = "World";

Here you use an undeclared variable.  Usually, you'll declare a variable 
with "my", so change to above line to:

my $greeting = 'World';
Hope that helps.
