Mike,
We are running on Solaris and UniVerse 10.1.6 Pick format. Here are the
results I got. It was on our development machine which is not quite as
beefy as our production system.
THE.START "60016" [16:40:16]
NAP.END "60118"
Average elapsed time of "NAP 1" is 10.20 milliseconds
Minimum value of "NAP 1" is 0 milliseconds
Maximum value of "NAP 1" is 1000 milliseconds
TIME.END "61118" [16:58:38]
Average difference of "TIME()" is 1000.00 milliseconds
Minimum difference of "TIME()" is 1000 milliseconds
Maximum difference of "TIME()" is 1000 milliseconds
