Hi Gregory,

my problem is not on like VFP store value.

My problem is a basic rule of any deterministic programming language:

if fn() is deterministic and v1=v2 then fn(v1)=fn(v2)

If VFP does not respect this rule by design, then

VFP language is a not deterministic language.

It is simple.

It is more hard, but i can work with a not deterministic language.
