re: Date performance

I applied Jon's suggestion (thanks Jon!) to my test 
program. There is
a catch : RPG-LE doesn't allow arrays to overlay other 
arrays.
I got around this by declaring a character array based on a 
pointer
set to %addr(the date array.)

This works and appears to be even faster. I consistently 
got 1
CPU-second run times.

Incidentally, in my first post, I had used an 8 digit 
packed field
for the date.I changed this to a 9 digit field, with no 
difference in
performance.
