I don't think you are understanding the increment notation. To increment
$saveNum($dup}, all you want on the line is this:
$saveNum{$dup}++;
not:
$saveNum{$dup} = $saveNum{$dup}++;

excellent, thanks for two great answers. I actually tried (! defined)
but i tried it on @storeList=<FILEIN>; which did not produce the
desired results at all : -(

Oddly enough, the above incrementing does not work on this example!!!!
try it for yourself if you want. If you change $saveNum{$dup}
=$saveNum{$dup}+1; to $saveNum{$dup} =$saveNum{$dup}++; it will not
increment anything, this actually through me off for awhile because i
always write ++ (not +1) ,....
well, i'll be $#%^&* i just ran the example with $saveNum{$dup} =
++$saveNum{$dup}; and it works exactly like i wanted, i didn't think
that would work?!,,....
oh yeah sorry about the multipul post's of the same question, first time
poster, they didn't show up for more then an hour, i didn't think they
would till i joined, blah, blah,.... ;-)
thanks again
