Re: [TCLUG:19613] [OT] perl boogage?



I get a syntax error using @#ITEMS.  However, $#ITEMS does equal 2 (in your
example).

$#array is the index of the last element in the array.  It is documented, I
have seen it many times, I just can't seem to find it right now.  I think it
was more useful in the past when you could set the starting index of arrays
to something other than zero.  I think you still can, but its discouraged.
I promptly forgot how to do that because it seems like such a bad idea.
