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.
