Sergey !

That did it, Thanks. The actual code was:
**
LOCAL oGrdMoverCfg
oGrdMoverCfg = ''
DODEFAULT(@oGrdMoverCfg)
xx = NEWOBJECT("frmengridmover", "encustom.vcx", "", oGrdMoverCfg)
xx.Show()

The dodefault calls method code in a custom object, and instance of which was dropped onto the scx form. As it turned out, I had to add the "@" to get an object reference returned. Once there, your syntax worked perfectly.

Thanks
Don Lowrey
