Abstract

A separate removal program is provided to enable safe removal of "hot- key" resident programs from the memory of a Personal Computer (PC). Resident PC programs, which are activated by a hot-key, commonly support a function whereby the resident programs can be removed from memory. Resident programs, which use no DOS functions, can be popped up at any time even while DOS is busy. If a resident program is popped up when DOS is busy and the user activates the function of the resident program to remove the resident program from the PC memory, the popped- up resident program will call DOS during the removal process to cause DOS to fail. As a result, the PC locks up. Lock up of the PC is avoided through employing a separate removal program, which can scan through the PC memory for a pop-up program.
