GLOSSARY OF TERMS

Ambiguous File Name:

A file name containing one or more wildcard characters. Ambiguous filenames refer to more than one specific file name and are used to refer to one or more files at a time.

AMSDOS:

AMStrad Disc Operating System. The program that allows Locomotive BASIC to access disc files.

Backup:

A duplicate copy of information used as a safeguard in case the original is lost or accidentally damaged. Making a backup refers to the process of duplicating a disc or disc file.

BDOS:

Basic Disc Operating System. This is the part of the CP/M operating system which provides an interface for a user program to use the functions of CP/M.

BIOS:

Basic Input/Output System. This is the hardware dependent part of CP/M that is written specifically for one type of computer. All the input and output to the screen, keyboard, disc and so on is performed through the BIOS.

Boot:

The process of loading an operating system into memory. When CP/M is started from BASIC a small boot program is loaded automatically from the disc, which then loads the rest of the operating system into memory.

Buffer:

An area of memory reserved for temporarily storing, or buffering, information during an information transfer.

Built-in commands:

Commands that are part of an operating system. They are always quicker than transient commands because they are not accessed from disc.

CCP:
