We have a couple programs with the paging and scrolling functions in place here and they are menu-driven and incorporate quite a bit of counter keeping but they work. At the time they were done I could find appropriate mapping to allow paging up and down but was stuck with having to use menu uptions--Yep, Down and Up-- for moving the cursor up and down a single line. In your instance--if you are really only displaying and it is meant to fit on a single screen--that becomes meaningless. Send a line direct if you have further interest. It was a tedious programming effort, but it can be done. > > it waits for the user to hit the ACCEPT key before the user is returned to the > menu.
