Assuming we have the following SQL stored procedure:

CREATE PROCEDURE usp_test 
	@Number	INT,
	@NewNumber INT OUTPUT
AS
SET @NewNumber = @Number + 3
RETURN @NewNumber
GO

In VFP we have valid ADODB.Connection object oConn and some variables. I want to use connection's Execute method:

LOCAL lnIn AS Integer, lnOut AS Integer, lnReturn AS Integer
lnIn=15
oConn.Execute("What?")

What would be the correct syntax for:
a) getting procedure's return value?
b) getting procedure's output parameter?

Microsoft claims that it is possible to execute a stored procedure as a native method of a Connection object. Something like this:

lnReturn = oConn.usp_test(lnIn, @lnOut)

I has not been able to get it working. Has anyone?
