A Method for Display Management to Provide User Replaceable Screen Updating Routine

Display management routines can be written following the ANSI X3.64 standards for display escape sequences. This makes code more portable, but it makes screen I/O very slow.

In accordance with the new method, display management routines are written using the ANSI X3.64 standards, but the code is arranged to make user replacement of the routines with machine specific code possible. That is, a user may easily substitute assembly language routines in place of ANSI standard routines. In most cases, replacing a routine with a user-written routine is as easy as duplicating the name of the equivalent function. Replacing items such as the attribute array is a little more difficult. Generally speaking, the most important thing to remember about replacing routines is to keep all of the global variables prop updated.
