            BY ÒOBERT ÒOSS


ÔHIS PROGRAM IS A DIRECTORY EDITOR
FOR ALL 1541 COMPATIBLE DRIVES (1541,
ÍÓÄ, ÉNDUS, ETC). ÉT WILL ALLOW YOU
TO READ A DISK DIRECTORY INTO MEMORY,
MANIPULATE IT (SORT, ADD, DELETE
ENTRIES, PROTECT / UNPROTECT ENTRIES,
ETC), AND WRITE THE UPDATED DIRECTORY
BACK ONTO THE DISK. ÔHIS WILL NOT
CHANGE THE PROGRAMS OR DATA ON THE
DISK, ONLY THE DIRECTORY. ÔRY THIS
PROGRAM ONLY ON TEST DISKS UNTIL YOU
ARE FAMILIAR WITH ITS OPERATION.

ÎÏÔÅ: SOME LETTERS STAND FOR
DIFFERENT OPTIONS WHEN SHIFTED.

               ÏÐÔÉÏÎÓ:

'R' READ DIRECTORY OF DISK IN UNIT 8,
     DRIVE 0

'L' LIST UP TO CURRENT ENTRY
'+' ADD 1 TO CURRENT ENTRY
'-' SUBTRACT 1 FROM CURRENT ENTRY
'Ã' SET NEW CURREN ENTRY
'I' MAKE SPACE TO INSERT ENTRIES

               ÓÏÒÔÉÎÇ

ÓORTING MAY BE DONE ON FROM 1 TO ALL
24 BYTES OF THE ENTRIES. ÓORT
DIRECTION (><) MAY BE SET FOR EACH
BYTE: '>' MEANS 'A' WILL PRECEED 'B'
AFTER THE SORT. 'WIDTH' (1-24) IS THE
# OF CHARACTERS USED FOR COMPARING
ENTRIES. '1ST' AND 'LAST' GIVE THE
ENTRY SORT RANGE.

'SPECIFY' ALLOWS THE ORDER AND
DIRECTION OF SORTING TO BE SET; THE
LETTERS A TO X STAND FOR THE 24
BYTES:

[A=FILE TYPE;
 B,C=TRACK,SECTOR OF FIRST BLOCK;
 D-S=FILE NAME;
 T,U=TRACK,SECTOR FOR THE FIRST
     SIDE SECTOR OF A RELATIVE FILE;
 V=RELATIVE FILE RECORD LENGTH;
 W,X=LOW BYTE,HIGH BYTE OF FILE
     LENGTH].

E.G.:'WIDTH'=1, ORDER="A...",
DIRECTION="<..." WOULD SORT BY
DECREASING FILE TYPE GROUPS.

'NAMES' SETS A DEFAULT ORDER WITH D-S
AT THE START AND ALL DIRECTIONS = '>'
