>What I didn't know and have come to realize is that VFP does not store the value of an expression in the memory variable. It stores the expression and display properties of that expression.

Larry,

I believe that that is incorrect. The variable has a number in it, not the expression. The presision of the nember is also stored. For example;

set decimals to 1
lnVar = 7/74*100
?lnVar && shows 9.5
? lnVar + .0000001  && shows 9.4#############

The numbers following the 4 are not 0's, so the actual value in teh variable is not 9.5 as was displayed, but is some other number which was rounded to 9.5 for display.

Also a Display Memory will show you the actual number stored in lnVar without regard to the set decimals setting. It appears that the ROUND() function is not using the displayed value but the actual value.
