I almost started the thread with I know this is false laziness but...
. You are right that this was well within my capabilities. I am not one to make excuses but I have been completely immersed in 6502 Assembly since last Friday afternoon. In fact, this code was to identify an execution path through some assembly. When the answer didn't immediately pop into my head I decided it was best not to think about it. I knew if I switched contexts from Assembly (which I am just learning) to Perl, the effort to regain where I was would be a lot of work.
