Hi Gregory,

I think you found a bug that still exist in VFP9. See code below

CLEAR
release aa
#define	ALINEDEFINED aa = aa
a=1
#define aa a
ALINEDEFINED
* The next two line should display the same
? [ALINEDEFINED]	&& aa = a  - Bug
? [aa = aa]		&& a = a   - correct
?vartype(aa), 'should be U', '  Error'
