Using @ARGV	Can't Post

I am trying to learn how to use command line arguments using @ARGV

I am just trying to put together something simple to see how everything works. For instance I want to type something like test.pl 1, test.pl 2, test.pl 3 etc. and have something different print out depending on which command line argument is used.

I know I would put the 3 arguments in the @ARGV array, but then how would I write the if statements
to print something different out for each option?

perl test.pl 1 2 3

test.pl:

print "$ARVG[0]\n";
print "$ARGV[1]\n";
print "$ARGV[2]\n";

if ($ARVG[0] == 1) {
print "The first value you inputted was 1! You must like the color red..."; ##sorry for the lame example, but you get the point :)
}

Ha....I finally figured it out.

I was thinking that you had to assign the list of possible values to @ARGV.....

Here anything put on the command line is automatically placed in @ARGV.

Once I figured this out all was a snap. Thanks;-)
