>i want to call a sqlserver procedure that make a calculation and send back the result to vpf. how to do it?

What result?
Is it a result set or just some value?

Both ways you could use a SELECT to generate VFP cursor:

? SQLEXEC(sqlHandler, "EXEC MySP","MyCursor")
BROWSE NORMAL


--- SQL Server SP MySP

SELECT * FROM SomeTable ...

--- Other version
DECLARE @SomeNumb number(10,2)
DECLARE @OtherNumb number(10,2)

SET @SomeNumb = 123
SET @OtherNumb = 12

SELECT @SomeNumb/@OtherNumb
