Re: Subfile "move to top" function

Booth,

I'm not sure what you mean by "Just do your subfile loop again, with no load." It's a load-all subfile, so all the records are loaded. I just want, for example, for SflRRN #4 to be displayed on the first line of the screen.

As far as using the mouse and scroll bars are concerned, unfortunately support for that is emulator dependent. In this case, we need to be avoid using a feature that depends on "special" support from an emulator.

The functionality I'm looking for is similar to a full screen line editor, like SEU. So if I want to copy a line, I would put a "C" in the subfile option source field and an "A" on the line I want the copied line to follow. I want full control of which page displays after the copy and where I want the cursor to end up.

First, yes, you have to write the subfile again, but you do not need to
reload it. Just do your subfile loop again, with no load.

This may not lend itself to your situation, but let the mouse button
double click equal the f-key you choose, and then the user just double
clicks the record.

As to the other issues, what do you have in mind?
