Consider the following situation:

We have program "M" calling program "S," which puts up a display file page requesting parameters for a multi-record operation.

Program "S" collects the parameters, puts up a "display-only" version of the page, and returns to "M," leaving that page up on the terminal screen.

Program "M" then runs through every record of the file, performing the operation requested through "S," which doesn't get called again. It doesn't put up a display page of its own until the operation completes.

(For the QuestView users out there, I've just described QuestView Search & Replace.)

Is there a way for "M" to update a message line on the page that "S" left on the terminal screen, without "S" having to be called, and without "M" having to rewrite the entire page?
