This section explains how to issue special control character sequences to:

• Control the position of the cursor
  
• Erase text from the screen
  
• Set the display mode
  
• Redefine the meaning of keyboard keys

ANSI extended screen and keyboard control sequences are supported in DOS sessions by ANSI.SYS, an installable device driver. In OS/2 sessions, these control sequences are supported by the ANSICALL component within OS/2 CHAR.DLL.

Note: In this section, unless otherwise specified, ANSI refers to both ANSI.SYS and ANSICALL.
