Need Help??

in thread PDL's error or mine?

You are perfectly right because I had a typo in my example. It should read ->which(...) instead of ->where(...). In that case, the condition cannot be violated.

OK... It was un-runnable pseudo-code anyway; and `which` as function expects single argument; and, as a method, should be called on a mask without other arguments, right? Even then, I'm confused, wouldn't you get exactly same result (i.e. `$intersect`) by simply `and`-ing ("`&`") the 2 masks and calling `which` on it? If example was just simplified for laymen to this tautology, I certainly expect no explanation, sorry to bother.	[reply] [d/l] [select]
