Useless use of string eqby Flubb (Acolyte)
|on Dec 06, 2007 at 14:33 UTC||Need Help??|
Flubb has asked for the wisdom of the Perl Monks concerning the following question:
My search-fu is weak because I can only find 1 reference to this problem anywhere. I want to check @ARGV, and depending what has been written there, alter a variable:
Running the program (command line is "arg.pl -arm -fet -10:00") produces: "Useless use of string eq in void context at ... line 5" for each line. So a number of questions:
1. Why is this a useless use?
2. What is a void context?
3. What can I do to do this better?
If you can pitch the answer at "humanities graduate" level, I will love you and bear your children.
