ALGORITHM A finite set of well-defined rules for the solution to a problem which may be duplicated over and over again to solve like problems.
ALLOCATE To reserve some physical resource (item) such as memory, disk file space, or other unit to a specific computer task.
ALPHANUMERIC A set of characters containing letters and digits.
ASCII American National Standard Code for Information Interchange. This is a standard code set used to exchange data between like or different computer systems.
BACK UP Duplicating data from one media to another to insure the availability of the data should a failure occur resulting in the loss of the original copy.
BATCH Programs which perform their tasks with a minimum of conversation with the computer operator and operate on more than one record during an execution.
BINARY The code set that has just two possible values: true "1" or false "0"
BIT A binary digit.
BLANK The space character.
BOOT To load the operating system from disk.
BUFFER An area of memory set aside for the reading and writing of data to and from a device.
BUG A program error (sorry).
BYTE A single character of computer memory or file space. The word V/BOSS uses 6 bytes.
CIR This is the symbol used to indicate that it is requested that the computer operator depress the <RETURN> or <ENTER> KEY.
CHARACTER A letter, digit or other symbol Which Occupies one location of memory.
CLASS A category for certain types of procedures or functions. For example class "FS" indicates "Flea Spray", "IN" indicates "Injections", "WO" indicates "Worm Medication", etc.
CONSTANT A fixed value.
CONTROL CHARACTER The key to the left of the "A" on the keyboard which is used in addition to another key. This expands the Possible number of values that the keyboard may send to the computer.
CURSOR The movable blinking marker used to indicate where the next character entered from the keyboard is to be printed on the display.
DATA All information which is entered by the user or used by the computer system.
DATA BASE A collection of records which have some logical relationship to each other.
DEFAULT A value used when none other is specified.
DOS Disk Operating System All of the program supplied by the vendor which interacts with the processor and storage media for the processing of data.

EXECUTE To perform an instruction or computer program.
FAULT An accidental condition which causes a piece of hardware to not operate correctly.
FIELD A specific portion of a record used to store some specific information.
FILE A collection or related information. It occupies space on either the diskette or hard disk.
FIXED LENGTH A format in which the size of the item does not change. In reference to a file; all records have the same number of bytes even though some of the information is not used.
FLOPPY DISK A diskette.
FONT A set of characters of a certain size and style.
FORMAT 1. To prepare a diskette or hard disk to accept data for a certain computer.
2. A particular arrangement and/or layout of data on magnetic media or display screen.

FUNCTION The procedure which causes a certain action on a given set of input.
FUNCTION KEY Any of the 10 keys labeled Fl through FlO at the extreme left side of the IBM PC Keyboard.
HARD COPY The printed output of a computer program.
HARD DISK Rapid access large capacity storage media.
HARDWARE The manufactured parts of a computer system as opposed to programs.
INDEXED FILE A data file organization residing on disk which has the ability to access records directly using logical keys. That is, the file contains records which the computer can find directly.
JULIAN DATE A date written in the format yyddd, where yy = current year, ddd = day of year. 84001 = January 1, 1984, 85365 = December 31, 1985. (Numbers will vary if Leap Year)
JUSTIFY To align characters in such a manner to fit the constraints of a required format.
K When referring to memory or storage capacity, 1024 in decimal.
LEADING The first part of a field. You may be required to type the "leading" zeroes in a field which is larger than the input.

LOG-IN/(ON) The process by which a computer user identifies himself to the computer and "requests" access to the various system functions.
M (MEG) In computer terms one million; actually 1,048,576 to be precise.
MATRIX PRINTER A printer in which each character is formed by a pattern of dots.
MENU A list of variables presented on the computer display from which the user may select an option.
MODIFY To change the contents of by retyping.
OPERATING SYSTEM The program which controls the execution of programs. XENIX and DOS are operating systems.
OVERLAY To use the same area of memory for more than one specific use. V/BOSS has many overlays.
PAD To fill the unused portion of a field with dummy data.
PAGE Part of the screen buffer that can be written on independently of other data.
PARAMETER This refers to a value which is given to the program. The Clinic Name configured in your system is a parameter.
PASSWORD A secret word known only to the computer user and computer system. The entry of this secret word assures the computer system that the proper user is attempting entry.
PATH A direction to find a file. It specifies the Device and Directory to which the file is subordinate.
PROGRAM A series of instructions which performs a task which is understood by the computer's hardware.
PROMPT This is the question the computer or program asks when it wishes you to input some information.
PROTECT To restrict access to certain resources.
PURGE Remove any unwanted records from a file. For example, after a few years have passed, you might wish to purge a year's rabies tag records from the file.
RAM Random Access Memory. The memory in the computer's processing unit as opposed to the storage capabilities of magnetic media.
RECORD A collection of related information treated as a unit.
RELATIVE FILE A magnetic media file organization in which records may be accessed directly by record number.
ROUTINE Part of a program which performs a certain task.
SCREEN See MENU, but its variation is that the user is required to input data and not just select an option.
