MS-DOS
Summary:
In Microsoft C versions 5.0, 5.1, 6.0, 6.0a, 6.0ax, and C/C++ version
7.0, when using the Output Text routines in the Microsoft run-time
library (version 5.1 "Microsoft C for the MS-DOS Operating System:
Run- Time Library Reference," pages 54-55), the two graphic modes,
_VRES2COLOR and _VRES16COLOR, have 30 text lines by default because of
their increased vertical resolution. All other graphics modes have 25
text lines when using these routines.
More Information:
The following graphics functions are the routines concerned with text
placement and output:
_displaycursor()
_gettextcolor()
_gettextposition()
_outtext()
_settextposition()
_settextcolor()
_settextwindow()
_wrapon()
The line numbers stated above are based on the default 8 x 8 font size
of the IBM ROM BIOS. Note that when using fonts, the number of text
lines in any video mode depends on the height of the font. For
information concerning changing from the default font size, see the
interrupt 10, function 11 entries in "IBM ROM BIOS," a Microsoft Press
book by Ray Duncan.
