Abstract

A method is described to cue user input at the prompt line. The Starburst character ASCII x`15' is used by some printers as a control character to begin compressed printing mode. If a menu were to use the same character on the prompt line of a menu, then, each time a screen is printed on such a printer, everything that is printed after the x`15' is printed in compressed mode. The user can turn off the compressed mode only by entering DOS and turning off the compressed mode via a command to the printer. In accordance with the new method, the prompt appears on the prompt line followed by the cursor marking the position where the user enters each choice. The Starburst x`15' was removed from the prompt line. Many characters were entertained as candidates for replacing the Starburst.
