Problem

Solutions: Shell: In reference to software, the term "shell" refers to the specialized program that allows the operator to enter commands and access the system resources. Known as the command processor, or shell, it is simply a user interface to the operating system, not the operating system itself. For example, the familiar default command processor for DOS is COMMAND.COM. You can change the default shell for DOS with the following statement in the CONFIG.SYS file: SHELL=C:\DEBUG.COM. You will be presented with the DEBUG dash prompt instead of COMMAND.COM's familiar prompt. But since DEBUG was not written as a shell, when you quit, your system will lock. Another example: The OS/2 shell program that loads when you boot is called the Program Selector. You start OS/2 sessions or run the DOS box from the Program Selector.
