I feel like I've just watched William Legrand climb up a tree and drop something.. I'm in the middle of a lesson or book but don't have the rest of it.
... what is option 5???
& press PAGE UP & PAGE DOWN & Enter (in that order???) .. page up might cause an error .. if you were at the top of the subfile, Otherwise PageUp followed by PageDown would usually get you to the place you started at. Pressing the Enter key could indicate that some processing should occur (but of course we don't know what) or perhaps that nothing should occur.
... what would be the output ???? What do they mean by output, perhaps what would the display look like?
It all goes back to the map that Legrand discovered when he was sketching the gold bug. (See Edgar Allan Poe)
Sorry,, that was a bit snarky.
We would love to help but you've got to give us more Info. Where did that question come from? What is option 5. What else should we know?
This is a question which, I suppose came from a textbook .. hopeufully not mine. Without reviewing the code I would guess (GUESS) that the difference would be that
on "the page at a time" load the deleted entry would be gone
on the other displays the screen row of the deleted item would still be used but would be blank.
