EDIRTN is a screen editing subroutine that implements only the most
common functions of KED/EDT.  We have found it useful for many applications.
The subroutine requires a VT100-type terminal and the EIS instruction
set, but could be changed to match other configurations.

Also included is a set of routines (VT100.MAC) which attempt to provide
most of the VT100 features to the high-level programmer.  Full documentation
is provided in comments at the beginning of the file.

Program ENTER is a sample program showing how EDIRTN and VT100 are used.
We use it to enter test questions into a computer assisted test construction
system which we have developed.
