This isnt an empty problem this is a transform bug

There is a KB article on this something to do with FP calculations

>*Hi FoxPro users!
>*We have found a serious Problem with the EMPTY() comparison.
>*The Code Sample uses a CURSOR Table, but you dont have to!
>*You could also use the values in variables
>
>local lnValue
>create cursor Test(value n(10,2))
>select test
>**Append Values in exactly this Order
>append blank
>replace value with 260.70
>append blank
>replace value with -31.60
>append blank
>replace value with -260.70
>append blank
>replace value with 31.60
>lnValue = 0
>select test
>scan
> lnValue=lnValue+value
>endscan
>wait window "Empty="+transform(empty(lnValue));
> +" ; lnValue="+transform(lnValue);
> +" ; Comparison on lnVALUE=0 is "+transform(lnValue=0) && This Value should be Empty()! But it isn't!

>*Serious Problem!

>*Same Problem with the Order of values

>*This Causes an error which is not displayed in transform
>*1
>*-0.1
>*-1
>*0.1
>*The difference is in the 37 Comma Digit of the value
>*This means for us.... we have to create an ORDER on every VALUE we want to ADD

>*OR

>*Never Compare a Value with empty() !!!!
