Thanks, Simon.

I understand that ".." is an operator that Ada coders are very fond of.
But what if the "UCASE" array was not a set of contiguous values from a
specific range?

In more general terms, how would we use a tested value as an index to a
lookup table to verify a property of that value from that table?

Not that this is necessarily a big deal.

Perhaps there's something about that Ada way that is grabbing me yet.
It should be obvious, but "obvious" in Latin means "overlooked."

Sorry for taking your time.


Thanks again
