Need a perl study-buddy

What happens if something besides 1 or 2 is entered as the option?

drop the -w switch from the shebang line. The warnings pragma is better:

use warnings;

Don't use parenthesis around print commands:

print ("You chose option 1. Enter your value below \n\n");

should be:

print "You chose option 1. Enter your value below \n\n";

print is not a function, using parenthesis can sometimes cause problems.

declaring the subs at the beginning of the script is also unnecessary:

sub one;
sub two;

You can drop that now before it becomes a bad habit.

when should i use

$a = <STDIN>;

and

my $a = <STDIN>;


whats the difference? =)

[KevinADC]

The short answer is you should always use the "strict" pragma and declare all your lexical variables with "my". The use of "strict" is a pretty lengthy topic, here is an article that discusses it more in depth:

perl.com: Beginners Intro to Perl - Part 6

The article is a little old but seems to still be relevant.
