Hi Mohammed,
1) don't use EVAL() in REPLACE command etc, because is't very slow
2) xfile is character memory and contain alias of table. If you want use it, you must use EVAL() or & (macro).

REPLACE IN (xfile) ;
   FOR &lcField.==LookUp(&xval., &lcField., &xval2.) AND
   NOT EOF(xfileF);
   newvalue with &xfileF..BILL_VALUE&& not works
