Hello Monks,

What am I doing wrong here?

#!/usr/bin/perl -w

use strict;
use Getopt::Std;

my $width = 500;
my $height = 500;

getopts( 'w:h:' );
if( $opt_w ) { $width = $opt_w ; }
if( $opt_h ) { $height = $opt_h ; }

print "$height:$width\n";

[download]

I get errors like so ...

Global symbol "$opt_w" requires explicit package name at ./adjust.pl l
+ine 14.

... and if I change my code to like so ... 
#!/usr/bin/perl -w

use strict;
use Getopt::Std;

my $width = 500;
my $height = 500;
my $opt_w;
my $opt_h;

getopts( 'w:h:' );
if( $opt_w ) { $width = $opt_w ; }
if( $opt_h ) { $height = $opt_h ; }

print "$width:$height\n";

... and run like so ...

$ ./my.pl -w 1000 -h 9

[download]

... I get this output ... 

500:500

... Looks like my.pl ignored the switches?


Please help.
Thanks

Its like a dog that can sing and dance.
It's remarkable because it can do it.
Not that it can do it well.
