Hello Joel,

Gosh, I've been busy on this topic!

Of course if the program had been written properly it would be doing bounds 
checking on the array index and 
would have sent a message weeks ago informing you of the approaching end of the 
array (assuming the element 
usage has ben gradually increasing -- I just love those 9999 element arrays -- 
we'll never fill that up!).

Even if this was just one of those things and the array simply isn't large 
enough ('cause too many of whatever 
is stored were added today) it should be possible to handle the situation.  For 
instance, log the failed data 
to a file, send someone a message, and process the log file later -- standard 
transaction update problem 
handling.  Please note that this is meant for the general case.  One can always 
think up specific scenarios 
where programmatically handling the error is not worth the effort.

A perfect case for dynamically allocating storage and using that for the array.

And that CL message indicates no (or very little) exception handling is being 
performed and you really don't 
want to know my opinion on that!! - even though the Cat, Dog, Rabbit, Impala 
message is useful to restart the 

I can see this append starting a whole war of words ...
