in reply to Re: using $ARGV without arguments
in thread using $ARGV without arguments
Question on acceptable practice.
Subject, warning on Use of uninitialized value in string eq at ...
When this happens, I go back and check my code to make sure it is OK the value is sometimes unitialized.
If it OK, I move on and dont worry about it.
Is this a bad habit???

Yes. Lots of Famous Really Good Programmers (tm) will tell you to always initialize vars---but since I'm not one of them, I'll tell you to at least try and make it a habit since it will save you grief later on. My rule is that if there is a chance that I'll check the value before I stuff something in it, I'll usually set it to a known value...
