drawing boxes and enlarged text graphics

[Gerald]

I need to make an interface for a dos 6.22 C program for some low end
computers with lousy graphics card. the standard text display is too small
so I need to draw my own text. Can someone guide me how to do this? In unix
I can use curses but I am not sure what utilities to use in dos.

forgot to mention using turbo C
I guess I will have to go back to defining arrays for each char to fill up
the screen with alphabets

There are some generic video resolutions according to the VESA standard,
that should solve your problem. You can switch the display from 25 rows
with 80 characters to something like 43 rows with 80 characters.

The standard DOS command for increasing the number of lines on the screen
is

mode con lines=43

Follow-Up set to alt.msdos

I would like to create a install.bat that will add a line to autoexec.bat to
call my program. However this line will not be added if it already exists.
May I know how do I go about writing my install.bat file? any help would be
greatly appreciated!

How about something like:

find "call myprogram" autoexec.bat > NUL
if not errorlevel 1 goto end
REM call myprogram line not found, append it to autoexec.bat
echo call myprogram >> autoexec.bat
:end
