Example: macro substitution

x='.T.' && no filter
REPLACE WHILE &X FF WITH ..

x='FF>3'
REPLACE WHILE &X FF WITH ..

Sergey, not replay to me with "x=''" and x='WHILE FF>3', thanks.

Another aspect of this problem ( this is not the same bug ):

CREATE CURSOR bugwhile (ff i,XX I)
* BUG 1
x=CREATEOBJECT("CONTROL")
X.ADDPROPERTY("Y",CREATEOBJECT("EMPTY"))
ADDPROPERTY(X.Y,"Z")
WITH m.x
* VFP SEE WHILE.XXX
	REPLACE WHILE (.Y.Z) ALL FF WITH 1
ENDWITH
