Basic question: Is there a "good" way for DOS direct screen writes to be handled? From what I have found so far MS-DOS programmers are expected to use BIOS services for screen writes. That is surprising but it is OK as it stands. However, how should things like the screen size (rows and columns) be determined? I know there is a BIOS call int 0x10-0f to get the columns but not the rows. Furthermore, under Windows the display size could even be changed as the program runs. I have seen programs that force a window to a specific mode/size (and kill the scrollback buffer at the same time). Possibly they are "real" MS-DOS programs...? ;-) Is there any standard or recommended way for programs to carry out direct screen writes (i.e. to arbitrary parts of the screen) that works in pure MS-DOS but also works well under Windows?
