The CRT unit.

  This chapter describes the CRT unit for Free Pascal, both under DOS and LINUX. The unit was first written for DOS by Florian klämpfl.

The unit was ported to LINUX by Mark May, and enhanced by Michaël Van Canneyt It works on the LINUX console, and in xterm and rxvt windows under X-Windows. The functionality for both is the same, except that under LINUX the use of an early implementation (versions 0.9.1 an earlier of the compiler) the crt unit automatically cleared the screen at program startup.

This chapter is divided in two sections.

• The first section lists the pre-defined constants, types and variables.
• The second section describes the functions which appear in the interface part of the CRT unit.
