Take a look at Alejandro Sosa's converter here in downloads. I don't remember whether he included my solution or developed some of his own, but basically you don't have to hack the .scx, you can build the DE on the fly (i.e. from a builder or converter) and then save the .scx with the DE object. Metacode would go like this:

oDE=createobject("dataenvironment")
oDe.AddObject("cursor1","cursor")
oDe.Cursor1.CursorSource=dbf("alias of your first table")
...
oDe.AddObject("Relation1","relation")
oDe.Relation1. (set properties here)
oForm.SaveAs(cNewScxFilename, oDe)

oForm object is what you have built converting or instantiated and got a references using ASelObj() function, i.e. an instance of your form in editor. Again, check Alejandro's converter, it should be doing all this already.
