1. Update Screen In Dos
How do you update the screen while making DOS programs? I know that using the
win32lib you can use repaintWindow() command, but DOS dosen't have luxury of
the sort. So is there an easy to update the screen in DOS mode? An example of
the code needed would be nice, thanks for the help.
P.S. Sorry for making two messages in a short time, but I just wanted to get
them answered as soon as possible.

Hello Andy,
I do a lot of DOS programing. To change screens use,
set_active_page(0)--on my computer I can get up to 4 screens
--(0 thru 3), see graphics.e to see may screens
--or MODES you and you computer are allowed to use
set_display_page(0)-- this is the page we are NOW looking at.
-- ditto there are 4 MODES avaible here.
--So now let's go:
set_display_page(0) --now everyone is looking at page 0
set_active_page(1) --here we get sneaky
puts(1, "***********hello world,whatever &"\n")
-- now all that is on page 1. But we ,the lookers, don't see this --
because we are3 looking at page 0.
--Now that we have finished UPDATING we can,
set_display_page(1)-- now everybody is looking looking at page 1
--leaving page 0 free for further tampering with
set_active_page(0)--I should point out that when you,
puts(1,"whatever"&"\n")--1 is the last active page you selected.
To further clarify and clear up any confusion.
in the example:
puts(1,"whatever"&"\n")
1 refers to the SCREEN. In this case the last ACTIVE page selected.
Hope this helps.

You need to understand that DOS does not behave like Windows. You (the
programmer) are responsible for redrawing the screen whenever your
program deems it necessary. There is no built-in mechanism like with
Windows.
