GOSUB and SCREEN

[Tyler]

Thanks Bill, that illustrates it very well.  I tend to think of / use screen
as being a handy way to position the cursor, not a sort of shelling out
process, so tt wouldn't be the behaviour I would intuit.

I used this in a class that I gave to demonstrate filePro logic on the
screen command.  If you try it, you might understand it better or you may
just understand from reading it.

@keys:::
::gosub chkthis:
::msgbox "Made it back to where I started" ; goto top:
chkthis:::
::screen "0":
::msgbox "I came back here":
::msgbox "I think I should return" ; return:
