Thanks Chip, Yes I generally don't like to short circuit functions especially in a loop I find that difficult to maintain.
My code is currently working except in the case where every item is checked and nothing was found. Is there a VB equivalent to the Perl line: return 0 unless ( defined( MyVariable I might still add code to the test condition, but right now I am using two variables and two embedded loops and I'll have to verify logic again. ) ) ) Best wishes, Jonathan On Feb 15, 2014, at 5:09 PM, Chip Orange <lists3...@comcast.net> wrote: > Hi Jonathin, > > First, you should not use the variable you are using to loop through your > collection, outside of the "for each" loop.
