Hi Martin,

>Nope. If you do "x=null", x is not a string, is null (no datatype).

i'm not agree with this.

If this is true, VFP have tons of bugs.

------
If you need to trap for such circumstance in which a character field can be null, you have to use Nvl( null, ""). This would return an empty string, what's very different from a null
------

I use this EVAL(NVL(....,'NULL')), and my request is for remove NVL().
