Hi,

On a display file a user can place the cursor on a line of text and use a function key to display another screen. All this happens in another module but in the same program.

When the procedure returns and the original text is displayed again, the cursor has moved. It is in the same position that it occupied on the screen displayed after using the function key.

Screen 1 line x, column y
F20 goes to data entry screen, first field at line x1, column y1.
F12 returns from the procedure.
Screen 1 line x1, column y1

How do I get the cursor back to its original line and column?

It's been a long time since I did any dspf programming. I know this
worked years ago when I wrote it but no guarantees.

You need this in the control record in the dspf source:
A RTNCSRLOC(&CSRRCD &CSRFLD)

A 43 CSRLOC(CSRROW CSRCOL)

A CSRFLD 10A H

A CSRRCD 10A H

A CSRROW 3S 0H

A CSRCOL 3S 0H

In the rpg pgm you need get the cursor position:

Ddspfds ds

D csrPos 370 371b 0

and before displaying the next screen:
csrrow = %div(csrpos:256);

csrcol = %rem(csrpos:256);

csrloc = *on;
