   What you have to do is specify them as pointers to that sort of 
record. No other changes other than those below should be required. Send 
me the code and I'll do it for you if you want.

  Therfore
LOCAL FN GetOffsetPos(LastPt as .Pts,MidPt as .Pts,SeamPt as .Pts,SeamPt2 
as .pts)
  becomes
LOCAL FN GetOffsetPos(LastPt as ptr to .Pts,MidPt as ptr to .Pts,SeamPt 
as ptr to .Pts,SeamPt2 as ptr to .pts)


and
FN GetOffsetPos(@LastPt,@MidPt,@SeamPt,@SeamPt2)
becomes
FN GetOffsetPos(LastPt,MidPt,SeamPt,SeamPt2)

  That's how I've always done it.
