if(@ARGV="h")

A single equals sign is an assignment operator. You're overwriting the value of @ARGV with "h". As "h" is true, that expression will always be true.

You need two equals signs to check equality. But that checks _numeric_ equality, so you actually need "eq"

if(@ARGV eq "h")

But that's still not right as that compares "h" to the number of elements in @ARGV. If the "h" will always be the first option on the command line, then you could do this:

if ($ARGV[0] eq 'h')

Or to cover more options, you could use this:

if (grep { $_ eq 'h' } @ARGV)

But really, you should look at one of the command line option processing modules like Getopt::Std or Getopt::Long.
