TextMode procedure
DECLARATION: TextMode(Mode : Word);
PURPOSE: Selects a specific text mode
UNIT: CRT
REMARKS: When TextMode is called, the following actions occur:
- The current window is reset to the entire screen
- DirectVideo is set to TRUE
- CheckSnow is set to TRUE if a color mode was selected
- The current Text Attribute is reset to normal
(corresponds to a call to NormVideo)
- The current mode is stored in LastMode
A call to TextMode(LastMode) will cause the last active
text mode to be re-selected. The following constants are
defined in the CRT Unit:
Const
BW40 = 0; { 40 X 25 B/W on a color adapter }
BW80 = 2; { 80 X 25 B/W on a color adapter }
Mono = 7; { 80 X 25 B/W on a Monochrome adapter }
CO40 = 1; { 40 X 25 color on a color adapter }
CO80 = 3; { 80 X 25 color on a color adapter }
Font8x8 = 256; { EGA/VGA 43 and 50 line }
C40 = CO40; { For Turbo 3.x compatibility }
C80 = CO80; { For Turbo 3.x compatibility }
