DirectVideo variable

Targets: MS-DOS, OS/2, Win32 console


CRT Unit

Enables and disables direct memory access for Write and WriteLn statements that output to the screen.

Declaration:
const DirectVideo: Boolean = TRUE;
MS-DOS target:
If DirectVideo is TRUE, Write and WriteLn procedures will store characters directly in the video memory, instead of using the BIOS to display them.

Win32 target:
If DirectVideo is TRUE, CRT uses simplified code for faster Write and WriteLn procedures execution.
