Standard UnitsThe CRT Unit
Targets: MS-DOS, OS/2, Win32 console
The CRT unit contains routines to control the keyboard and monitor.
This unit, with over 20 functions and procedures, allows for a powerful
interface to be developed between the program and the user.
To the end user, a program's appearance and interface are essential
aspects that cannot be ignored. With CRT, programming window displays
and keyboard handling is a breeze. In the initialization code for CRT,
output to the monitor or screen is redirected from the console standard
input and output files to the direct screen I/O.
Redirection is possible only if the Input and Output file are assigned and
reopened.
The CRT units allows one to easily create OS/2 and Win32
console applications.
Only few specific differences remains between MS-DOS, OS/2 and Win32
implementations of CRT unit. All these differences are described
in this chapter of help.
