My SQL stored procedure looks like:

ALTER procedure [dbo].[Candidate_Insert_Blank] (@CreatedByID int, @Return1 int output, @Return2 int output)

My native VFP code looks like:

Return1 = 0
Return2 = 0
lnReturnCode = SQLExec(lnConnectionID, 'exec Candidate_Insert_Blank ?1, ?@Return1, ?@Return2', '')

Therefore, I'm already passing by reference, am I not?
