Hey MS - Any plans to change of "fix" this.


I agree with you,
but it is a Function,
and therefore it is necessary to estimate all the parameters before executing of the code.

Of course VFPT can crack this standard schema,
but i think that this event non occur on the future VFP releases.

EVL() and NVL() are usefull with a :

EVL(EXPRESSION,surrogateCostant or Variable)
NVL(EXPRESSION,surrogateCostant or Variable)

but if second parameter is slow to evaluate, use IIF(),

IIF(ISNULL(EXPRESSION),surrogateCostant or Variable,EXPRESSION)

but if EXPRESSION is slow to evalute or worse, it is not deterministic,
you must to please you of:

varExp=EXPRESSION
IIF(ISNULL(m.varExp),surrogateCostant or Variable,m.varExp)
