Re: Test for parameters?

You probably mean @ARGV instead.

Checking the index of the last element of the array is rarely the best option, too. In scalar context, the array gives you the number of elements -- that works very well in the boolean context used here:

die "Exiting without parameter.\n" unless @ARGV;

ARG!!!!!!! It is absolutely insane how freaking stupid things get. Yes, @ARGV. @_ is when passing parameters to FUNCTIONS, not into the script itself. See, I know this. I think I need sleep. Thank you so much. Maybe I just need caffein? Anyway, I really appreciate that. Every now and then I just need somebody to take a 2x4 and smack me back into reality. ~~Guildencrantz	[reply]
