Hi,
I'm not entirely sure that I understand your requirements but this
might get you started.
You want to scope your variables with the keyword `my`, so
#!/path/to/perl
use strict;
use warnings;
...
foreach my $colour (qw/red green yellow blue/) {
print "$var\n"
}
red
green
yellow
blue
The variable $colour will be changed with each iteration of the loop.
Have a look at
http://perldoc.perl.org/perlsyn.html#Foreach-Loops
for more details.
HTH,
Dp.
