Hi!

DECLARE SINGLE JaargiftReken IN NAdvies.DLL ;
INTEGER, ;
INTEGER, ;
INTEGER

lNLV = 200
lDr = 10
lg = 2
? JaargiftReken (lNLV, lDr, lg)

"@" passes variable by reference, that is a pointer in Delphi. Just for integer, do not use "@".

I also not sure about "Single" here - the size of "single" type might be different in Delphi and VFP, though I think it should work ok.
