   of the CDU-package for free. Look into the details in REGISTER.CDU
   For Non-commercial users there is a POSSIBILITY to submit to one
   of the special contracts as explained in the file REGISTER.CDU;

 - Commercial usage of CDU will cost some money. Also, a so called
   'closed' Bulletin Board System (a system where the user must pay
   direct to the SysOp to get full access) is considered as a com-
   mercial user. Both types of users should look into the details in
   REGISTER.CDU;

 - The registration of the CDU-package will licence ONE copy for use on

 - Support on CDU, when used in a non-commercial environment, is
   available by means of written letters or by entering the inter-
   national echomaol area DISP;

 - Problems and suggestions can be entered in the FidoNet <tm> Echomail
   conference <tm> called DISP (international). Entering this echo does
   not exclude you of the duty to register the CDU-package, though users
   who evaluate the product can enter the echo for questions;

   area;


 1.2 Newer versions and contacting the author
 ────────────────────────────────────────────────────────────────────────
 The newest version of CDU is always available at the DISP-HQ on node
 2:512/100. CDU is also distributed thru a number of DISP support nodes.
 There are three ways of obtaining newer versions of CDU:


 - Logging on at DISP-HQ or a support node
   Look into the file SUPPORT.CDU for a full list of support noded;

 - Logging on to a SDS node
   CDU is distributed thru SDS/SDN, but only big minors (x.10, x.20 and
   so on) and majors (14.01, 15.01 and so on) are submitted to the SDS
   distribution point in Holland;

 - Logging on to your own BBS;
   Chances are, that you will find an older version (international
   users) because it will take some time for the new version to
   'bleed' thru the net;

 - Update service;
   You can enter a special update service (read REGISTER.CDU).


 If you think you have found problems in CDU, or in any other case,
 you wish to contact the author, you can send me:

 - A letter to the address you can find in the header of this file;
 - A NetMail <tm> message to Rob Van.hoeven (please mind the point
   between Van and Hoeven) at 2:512/100 or (better) 2:512/100.5;
 - A Message in the FidoNet <tm> DISP echomail <tm> area;

 2.1 Preface
 ────────────────────────────────────────────────────────────────────────
 Please notice the following:

 - CDU is a ShareWare product in every right way, this means this
   software is not crippled in any way;

 - This program only works when you work with the original CATDISK pro-
   gram. CATDISK <tm> is (c) 1986-91 by Rick Hillier;


 2.2 Requirements
 ────────────────────────────────────────────────────────────────────────
 CDU requires:      - PC XT/AT/386
                    - At least 200K free memory but it depends on the
                      options (picklist) you use;
                    - DOS 3.xx and higher;
                      (tested with 4Dos 3.02, should work with lower
                      versions). Tested with DOS 5.0;
                    - HDU optional
                    - The original CATDISK program;



 2.3 History
 ────────────────────────────────────────────────────────────────────────
 In the early '90 I got tired of my diskettes and their files. I needed
 a diskette catalog program. I tried a few of them, including CATDISK
 but all, also including CATDISK, seemed to slow for my VERY slow PC,
 so I did write a small program myself that was nicer than most in-
 memory catalog programs but did not include many options.

 When I finally installed a new PC at home (a 386/33er) and also hooked
 on as a co-sysop for 2:512/100, my files started to grow. Because I
 more or less function as a remote backup for the BBS-files, my collec-
 tion raised from 50 360Kb diskettes to more than 200 720/1.44 diskettes,
 all containing archives.

 I was surprised that I suddenly saw a new version of the CATDISK <tm>
 program (4.60 that was), and decided to try it again. By now I have
 created some 'small' customized programs that can help you with some
 tasks in CATDISK <tm> that are not available or too specialized for
 CATDISK <tm> to do.

 These programs, though they can be better, do their jobs and are now
 shared with you. The easiest thing you can do, is to delete them but
 there could be one or more that suit your needs. In any case, if you
 have comments or suggestions, let me know.

 3.1 Installation
 ────────────────────────────────────────────────────────────────────────
 This installation is uncommon to my products. That is, because there
 are almost no options to set <grin>. Lets walk thru the installation:

 - Copy the *.EXE files you need (or all of them) to a directory in
   the DOS-path;

 - Create a line in AUTOEXEC.BAT where you set the environment varia-
   ble CATBASE. This variable must point to the directory that con-
   tains the CATDISK.DTA/SUM files and/or any other CATDISK <tm>
   database you have. An example (where the CATDISK.DTA/SUM files
   are in C:\CATDISK):

   SET CATBASE=C:\CATDISK

 - If you normally run CATDISK with special option (the /F[xxx] not
   included, this option is inserted by some of the CDU programs
   itself), you must create a line in your AUTOEXEC.BAT with the
   following format:

   SET CATPARM=[switch] {switch} .. {switch}

   Where [switch]/{switch} are the command-line options you normally
   use to start CATDISK. If normally you start CATDISK with /NZ and
   /NZC, the line should be 'SET CATPARM=/NZ /NZC' (wthout the quotes).

│  This is NOT needed when you already have defined a CATDISK environ-
│  ment variable for CATDISK itself ! If BOTH variables are present,
│  all CDx programs will first use the values from the CATDISK env.var.
│  and will APPEND all values from the CATPARM env.var. to these values;

 - Be sure to have, at least, CATDISK.EXE in the same directory as
   the variable CATBASE points to. If it is not there, copy it to
   that directory. This is only needed when CDR and/or CDM is used;

 - Read the remainder of the documentation and try it out (after you
   have made the CATBASE env.var. active!);

 - Previous releases contained a program CDD.EXE. This program could
   not be called by that name when you run 4DOS <tm> on your system.
   For this reason it is renamed to CDR.EXE. You should remove any
   older CDD.EXE (from the CDU package!!) from your disk;

 4.1 General program description
 ────────────────────────────────────────────────────────────────────────
 All programs described below work more or less the same. If you have
 more than one CATDISK <tm> database, you can select to point to the
 wanted database by means of a command-line switch (/BASE=) or by means
 of a PICK-list. If you have more than one database and you do NOT sup-
 ply the /BASE= parameter, the program will show a PICK-list with all
 eligable databases. Just move the bar to the right database and hit
 the [ENTER] button. All programs have some common command-line para-
 meters that can be used. You can use /?, /H, ? or H to display the
 valid command-line parameters for each of the programs.

 All CDx programs that use a file-mask, contain one EXTRA mask that
 is normally not available in DOS. The '=' mask can be used for a
 'shifted' test. Some examples explain it best:

 =RA   will select tRAns.arc, RA_101.zip, warnRAm.arj and so on
 =A.E  will select mamA.Exe and so on;

 You can not combine the '=' mask with other masks like ?? and ** !


 4.2 CDC
 ────────────────────────────────────────────────────────────────────────
 CDC is the smallest and easiest program. Sometimes the CATDISK <tm>
 databases will contain 'grabage' characters in some fields. Though it
 should be fixed, it is still possible that your databases contain
 these characters. These characters do no harm but they can be a pain
 in the neck in the case when you want to compress your CATDISK <tm>
 database(s). If you use programs like DIET or the resident STACKER,
 you can get some extra bytes of compression back when the fields in
 the CATDISK <tm> databases are set to hex '00' for that part of the
 field that is NOT in use.

 CDC should be run once in a longer period and does nothing more than
 cleaning all garbage in the CATDISK <tm> database. It should not al-
 ter the active information but when you are unsure, you must backup
 the database first.

 CDC works with the following command-line options:

 /BASE=nnnnnnnn   You can use this parameter to point to the right
                  CATDISK <tm> database. [nnnnnnnn] is the name
                  (without extension) of the database. If there is
                  only one database, CDC will use it at once. If
                  there are more databases and you don't use this
                  parameter, CDC will show all possible databases
                  and you can pick one of them;


 4.3 CDR
 ────────────────────────────────────────────────────────────────────────
 CDR is a nifty utility that can help you to clean your diskette files.
 CDR is the CATDISK <tm> delete utility. In general, you can use this
 program in 2 ways.

 - Normal delete (with extra mask)
   You will start CDR with one or more file-masks to delete;

 - Date-delete
   You can delete files that are older than a certain month and year;

 When CDR is started, it will search the database for all matches (you
 can supply up to 50 ! masks) and will sort them on volume-ID after
 you have been presented with a question if one or more (or even all)
 of the matched files have to be deleted. Then CDR will ask you to
 mount the first volume, the next volume and so on. CDR will combine
 all files on one volume so you only have to mount diskettes only once.
 They will be asked in volume-ID sorting order and only diskettes that
 contain files to be deleted are asked for a mount.

 After the file(s) are deleted for a specific volume, CDR will call
 CATDISK <tm> and you can update the catalog with the original CATDISK
 program.

 CDR works with the following command-line options:

 /BASE=nnnnnnnn   the same as with CDC

 /TOOLD=mmyy      mmyy is a valid (4 digit) month and year. When you
                  supply this parameter, CDR will only delete files
                  that equal one of the masks AND are OLDER than the
                  supplied mmyy combination;

 /DRIVE=d         CDR would like to know the drive that contains the
                  diskettes that are worked on (delete files). If
                  you do not supply the option, CDR will ask for the
                  drive-letter;

 /NORESTART       When you terminate CDR while CDR is busy with the
                  manipulation of diskettes (the second part), you
                  can start CDR again and it will go on as if nothing
                  has happened. Any selection screens are skipped and
                  CDR will go on with the next volume in the list. If
                  this is NOT what you want, you can supply /NORESTART
                  and CDR will start from scratch again. If you did
                  finish CDR in a NORMAL way (not pressing ESC), the
                  restart files are scratched and CRD will start from
                  scratch the next time. You can also force CDR to
                  start from scratch (after abnormal termination) by
                  deleting the files CDR$$???.??? from disk;

 /NOSTUFFKEY      Normally CDR will stuff a CR, 5, 'YYYY' and ESC
                  into the keyboard before CATDISK <tm> is started.
                  This is needed and you should observe well that
                  CATDISK <tm> will terminate again. If it does NOT,
                  an error was encountered and you must manually go
                  into the menu 5 and hit Y twice. When you enter
                  /NOSTUFFKEY as a command-line option, CDR will not
                  stuff any keys into the keyboard and you should
                  do all the work inside CATDISK <tm> yourself;

 /CDISK4          If you still run CATDISK 4.xx, you must supply
                  this option unless you also supplied the /NOSTUFFKEY
                  option. If you let the program stuff the keys in the
                  keyboard before CATDISK is started, the program will
                  use the CATDISK 6.xx keys (catalog is entry 5) unless
                  you use /CDISK4 (catalog entry is 4) in which case
                  the program will use the old format;

 4.4 CDF
 ────────────────────────────────────────────────────────────────────────
 CDF look much like CATDISK internal file-list but it is somewhat faster
 and has some extra options. You can use the movement keys to scroll
 left, right, up and down the list and you can use up to 50 masks in
 one run. Also the enhanced masks can be used ('='). One extra option
 makes it possible to show the diskettes in free-space order so you
 can easy select a diskette that can fit your new file.

 CDF works with the following command-line options:

 /BASE=nnnnnnnn   the same as with CDC

 /FREE            Only show diskettes in free-space order

 /ARC             Display in-archive files also;


 4.5 CDM
 ────────────────────────────────────────────────────────────────────────
 CDM is something you must try. Put all new files that have to go to
 diskette into one directory on your hardisk (use separate directories
 for files that will go into separate diskette-sets e.g. CATDISK <tm>
 databases). Start CDM.

 CDM will first try to look if older versions are already inside the
 diskette collection (e.g. SCAN82 is on ARCHIVE 10 and now you have
 SCAN83 ready to store on diskette). Also equal files are detected.

│For equal files, CDM will ask if you want to delete the file from
│hard-disk (answer 'Y'). If you reply 'N', CDM will add the file to
│one of the diskettes and BOTH (name-like) versions will reside on
│diskette. If you answer 'A', CDM will remove the file from diskette
│and will add the one from hard-disk to a new diskette !!

 The algorithm to detect different versions is far from perfect. Only
 files with names of 5 bytes or longer (excluding the extension) and
 with the last 3 bytes unequal but the first bytes equal, are marked.
 So, CT21 and CT53 are not detected but MTA_VE14 and MTA_VE16 are.

 Now CDM will try to fit the new files on your diskettes in a way that
 the diskettes are filled optimal.

 This all will only use one mount per eligable diskette. After a
 diskette is ready, CDM will call CATDISK so you can update the
 database. CDM works at my place but not everybody will store files
 in the way I do, so try before you use.

 CDM works with the following command-line options:

 /BASE=nnnnnnnn   the same as with CDC

 /DRIVE=d         the same as with CDR

 /NORESTART       When you terminate CDM while CDM is busy with the
                  manipulation of diskettes (the second part), you
                  can start CDM again and it will go on as if nothing
                  has happened. Any selection screens are skipped and
                  CDM will go on with the next volume in the list. If
                  this is NOT what you want, you can supply /NORESTART
                  and CDM will start from scratch again. If you did
                  finish CDM in a NORMAL way (not pressing ESC), the
                  restart files are scratched and CDM will start from
                  scratch the next time. You can also force CDM to
                  start from scratch (after abnormal termination) by
                  deleting the files CDM$$???.??? from disk;

 /NOSTUFFKEY      Normally CDM will stuff a CR, 5, 'YYYY' and ESC
                  into the keyboard before CATDISK <tm> is started.
                  This is needed and you should observe well that
                  CATDISK <tm> will terminate again. If it does NOT,
                  an error was encountered and you must manually go
                  into the menu 5 and hit Y twice. When you enter
                  /NOSTUFFKEY as a command-line option, CDM will not
                  stuff any keys into the keyboard and you should
                  do all the work inside CATDISK <tm> yourself;

 /CDISK4          If you still run CATDISK 4.xx, you must supply
                  this option unless you also supplied the /NOSTUFFKEY
                  option. If you let the program stuff the keys in the
                  keyboard before CATDISK is started, the program will
                  use the CATDISK 6.xx keys (catalog is entry 5) unless
                  you use /CDISK4 (catalog entry is 4) in which case
                  the program will use the old format;

 4.6 CDS
 ────────────────────────────────────────────────────────────────────────
 This is a nice utility if you get many request for copies of your
 files. CDS will sort the files from new to old, will ask if you would
 like to select each individual file and will show the number of bytes
 you have selected. When you stop selecting files, CDS will start to
 ask for diskettes and will copy files from the diskette to the current
 directory. Also a FILES.BBS alike file, containing any comments from
 the CATDISK <tm> database you selected, is copied onto the disk.

 CDS works with the following command-line options:

 /BASE=nnnnnnnn   the same as with CDC

 /DRIVE=d         the same as with CDR

 /NORESTART       When you terminate CDS while CDS is busy with the
                  manipulation of diskettes (the second part), you
                  can start CDS again and it will go on as if nothing
                  has happened. Any selection screens are skipped and
                  CDS will go on with the next volume in the list. If
                  this is NOT what you want, you can supply /NORESTART
                  and CDS will start from scratch again. If you did
                  finish CDS in a NORMAL way (not pressing ESC), the
                  restart files are scratched and CRS will start from
                  scratch the next time. You can also force CDS to
                  start from scratch (after abnormal termination) by
                  deleting the files CDS$$???.??? from disk;

 ┌───────┬────────────────────────────┐
 │ 1.01  │ First rudimental release   │
 └───────┴────────────────────────────┘

 ┌───────┬────────────────────────────┐
 │ 1.02  │ Bug release (only CDD)     │
 └───────┴────────────────────────────┘
  CDC
  ■ Nothing changed, not supplied in 1.02

  CDD
  ■ CDD would incorrect detect files that were to old. Newer files
    were not deleted but some of the older files could stay on the
    diskette library. This is fixed;

  ■ CDD first sort out the possible deletes. Then CDD would ask for
    volumes and at THIS moment the user could reply Y/N. This order
    is changed. CDD will sort out the matches and will ask a Y/N
    before ANY volume has to be mounted;

  CDF
  ■ Nothing changed, not supplied in 1.02

  CDM
  ■ Nothing changed, not supplied in 1.02

  CDS

 └───────┴────────────────────────────┘
  CDC
  ■ Only some cosmetic changes;


  CDD
  ■ Added /RESTART;

  ■ Added /NOSTUFFKEY to overrule the stuffing of keys into the
    keyboard to run CATDISK <tm> almost unattended;

  ■ Added option to 'Q'uit the selection process. CDD will start with
    the files you selected sofar. Hitting [ESC] in the questionaire
    will cause CDD to terminate;

  ■ Some cosmetic changes


  CDF
  ■ Some cosmetic changes;

  ■ A mask is not needed anymore when you use /FREE;


  CDM
  ■ Added /RESTART;

  ■ Changed some cosmetics;

 ┌─────┐
 │ CDR │
 └─────┘
  ■ Changed the name from CDD.EXE into CDR.EXE;

  ■ Changed the parsing routines for labels on diskette a bit. This
    should fix problems with labels containing binary zeroes. Also
    all labels are looked at in uppercase manner;

  ■ Fixed a problem where CDR would display invalid dates on the
    selection screen;

  ■ Added support for CATDISK 6.xx (other stuffed keys). Old CATDISK
    releases are still supported with the /CDISK4 command-line option;

  ■ Added support for user-switches, normally used with CATDISK,
    by looking for the environment variable CATPARM;

  ■ Recoded the restart procedures, removed the /RESTART option and
    added the /NORESTART option to switch automatic restart off;

 ┌─────┐
 │ CDC │

  ■ Changed some internal routines a bit;

 ┌─────┐
 │ CDR │
 └─────┘
  ■ Fixed a serious bug in the parsing of volume-labels. This caused
    CDR NOT to recognize some (or all) diskettes. This is fixed;

  ■ CDR did recognize the /CDISK4 command-line parameter but forgot to
    do something with it. This is fixed;

  ■ CDR will now look if there is a CATDISK env.var. available and
    will use the values;

  ■ CDR will now work with registered versions of CATDISK <tm>;

  ■ CDM will now look if there is a CATDISK env.var. available and

  ■ CDM will now work with registered versions of CATDISK <tm>;

  ■ Changed the algorithm for duplicate files. You can now make three
    different choices. Either you remove the file from the hard-disk,
    you add the new file to diskette (so both will exist on diskette)
    or you can remove the version on diskette and add the one on hard-
    disk to diskette (Y,N or A);
