This Turbo Pascal include file is a display and data entry tool. It Displays
a given String (or Character Array), Integer, or Real (Dollar) data field
in a given screen area and allows the operator to make changes via the
keyboard. It allows the operator to end the editing using many ending
keys and passes information about those keys to the calling program.
