CDOSSAP.* The SAP utility from CPMUG rewritten for CDOS 2.36
CDOSCOPY.* The literal COPY pgm from CPMUG modified for CDOS
  2.36 (Standard 8" to Double Density, Double Sided operation)
CDOSFMAP.* The FMAP utility from CPMUG Vol 8 modified  to
    reflect the changes in Vol 40 and to accomodate the 512
    directory entries possible with CDOS
CDOSUCAT.* The UCAT utility from CPMUG modified to reflect the
    updates in Vol 40 and to accept wildcard ignore names of
    the form ????????.SYM, etc
CDOS.DOC A few hints for users of CDOS 2.17 or higher

These programs are public domain because:
They are updates of earlier CPMUG releases which have been
altered by the author.


To whom would this program be useful:
All users of CDOS versions 2.17 to 2.36


Briefly describe the program function:
CDOSFMAP.*
CDOSUCAT.*
These programs allow use of the Master Disk Catalogue scheme
with CDOS 2.17 to 2.36. (The original CAT.COM is still OK).

CDOSCOPY.*
Operates as per earlier CPMUG release for 8" S/D disks.
For Double Density or Double sided disks a 'Read/Write Logical
Block' approach is used to copy the disk. Although not yet used
with 5" disks the modification is simple.

CDOSSAP.*
the SAP utility from the CPMUG rewritten for CDOS to reflect
differences in handling:
Disks other than Single density Single Sided,
The CDOS disk label
CDOS file protect attributes.


Where is further documentation available:
See CDOS.DOC
The author will supply additional info on individual request.


Hardware dependencies:
All hardware consistent with CDOS 2.36 OK
Hard Disk not supported by CDOSCOPY, CDOSSAP


Software dependencies:
Requires Cromemco CDOS version 2.17 to 2.36


Source processor:
Cromemco Z80 assembler version 2.05 or higher
CDOSFMAP |
CDOSUCAT |  require MAC

Does the software "drop in":
Yes


How easy is the code to modify:
.Z80 files fairly well documented in relevant areas
