Re: Subfile "move to top" function

A couple of thoughts:

- MOUBTN() is a useful keyword.

- "SFLSCROLL (Subfile Scroll) keyword for display files

You use this field-level keyword in the subfile-control record format to
return the relative record number of the subfile record that is at the
top of the subfile when control is given back to your program."

Is that of any use in the process you desire, Mark?
