I'm not posting the multiplier.  I'm posting to
recommend against using a MULT operator to perform
date conversions.  I did some performance comparisons
a long time ago and found that using MULT to convert
a date was 100 to 150 times slower than 3 MOVEs.
Furthermore, when you do move to RPG IV, the technique
does not work if you use TRUNCNBR(*NO), or if you do
the multiplication in an expression.
