404 Error Messages
64 FILE TYPE MISMATCH
The designated file type of a requested file was not the same as the file's type
on the diskette.
65 WO BLOCK
The block designated in a block allocate (B-A) command was already
allocated. The track and sector returned indicate the next available block
with a higher number. If no block with a higher number is available, zeroes
are returned.
66 ILLEGAL TRACK AND SECTOR
The designated sector does not exist on the diskette. This can be caused by
an attempt to direct access an illegal sector or by a corrupt track/ sector link
to the next block in a file.
67 ILLEGAL SYSTEM T OR S
The DOS attempted to access an illegal sector.
70 NO CHAmSTEL
The designated channel was already in use, or all channels were in use. Five
sequential files, or six direct-access channels can be open at any one time.
71 DIRECTORY ERROR
The BAM in memory is corrupt. Either allocation has been performed
incorrectly or the BAM in memory has been overwritten. The diskette can
be reinitialized to correct this problem, but active files may be affected by
this action.
72 DISK FULL
All of the data blocks, or all of the directory area on the diskette, has been
used.
73 DOS MISMATCH
This message can occur when an attempt to write on a disk formatted by
another version of DOS is made. More often it occurs when the drive is first
turned on; the message can be ignored.
