BY ÄAVID ÓTIDOLPH

ÃOMMODORE FILES HAVE NAMES AND OTHER
INFORMATION ABOUT THEM STORED IN THE
DISK DIRECTORY. ÔHE DISK DIRECTORY IS
ORGANIZED INTO BLOCKS, EACH OF WHICH
HAS 8 FILES. ÔHE PROGRAM FOLLOWS THIS
STRUCTURE. ÉF YOU DON'T SEE THE FILE
YOU WANT IN THE FIRST BLOCK, GO TO
THE NEXT ONE UNTIL YOU FIND IT.

ÔÈÅ ÍÁÉÎ ÓÃÒÅÅÎ:

ÔHE MAIN SCREEN TELLS YOU EVERY THING
YOU NEED TO KNOW ABOUT EACH DIRECTORY
BLOCK. ÏN IT IS THE FILE NAME, FILE
TYPE, AND THE STATUS OF THE FILE (IF
THE FILE HAS BEEN DELETED AND IF THE
FILE IS PROTECTED). Á FILE IS CHOSEN
BY USING THE UP AND DOWN CURSOR KEYS
TO HIGHLIGHT THE FILE YOU WANT.

ÂELOW THE LIST OF FILES IS THE
COMMAND LIST. ÏNCE YOU HAVE CHOSEN
THE FILE YOU WANT, IF ANY, IN THIS
BLOCK OF 8 FILES, YOU USE THE CURSOR
LEFT AND RIGHT KEYS TO HIGHLIGHT THE
COMMAND YOU WANT. ×HEN THE FILE AND
COMMAND SELECTORS ARE WHERE YOU WANT,
YOU PRESS THE ÒÅÔÕÒÎ KEY. ÍOST
COMMANDS ARE EXECUTED IMMEDIATELY,
BUT SOME COMMANDS NEED TO USE THE
DISK DRIVE SO IT TAKES TIME (JUST
WAIT).

ÃÏÍÍÁÎÄ ÓÕÍÍÁÒÙ

ÎÁÍÅ: ÓOMETIMES IT IS NECCESARY TO
CHANGE THE FILE NAME OR FILE TYPE.
ÏNE EXAMPLE IS HAVING A SERIES OF
DASHES SEPERATING FILES LIKE ON YOUR
INTRODUCTORY ÃÏÍÁÌ DISK. ÂECAUSE THE

CREATE DUPLICATE NAMES. ÉF YOU DO NOT
WANT TO CHANGE THE FILE NAME (OR FILE
TYPE) JUST HIT RETURN.

THE FILE FROM BEING DELETED
(SCRATCHED) ACCIDENTALLY. ÔHE ONLY
WAY TO ERASE SUCH A FILE IS BY

COMMAND IS DONE OF A DISK WITH A
PROTECTED FILE, YOU WILL SEE A '<'
NEXT TO THE FILE TYPE. ÔHAT WAY YOU
WILL KNOW IT CANNOT BE ERASED. ÔHIS
APPLIES TO ÁÌÌ FILES, NOT JUST ÃÏÍÁÌ
PROGRAMS.

ÕÎÐÒÏÔÅÃÔ: ×HEN YOU NEED TO ERASE A
PROTECTED FILE WITHOUT ERASING THE
ENTIRE DISK YOU MUST USE THIS COMMAND
TO UNPROTECT IT FIRST.

ÒÅÓÔÏÒÅ: ÉF YOU DELETED (SCRATCHED) A
FILE AND WANT IT RESTORED IT IS
POSSIBLE. ÉF YOU HAVE WRITTEN TO THE
DISK AFTER THE FILE WAS DELETED, YOUR
FILE IS PROBABLY DESTROYED. ÔHE

COMPLETELY RESTORE THE FILE
(INCLUDING THE ÂÁÍ). ÔHE PROCEDURE IS
AS FOLLOWS:
