- INDEX is a CP/M (R) utility program combining the features of DIR and
- STAT. It provides an alphabetical listing of the disk directory, spaced in
- columns across the screen, and may include the file size for each entry. The
- total number of files, the total number of directory entries used, the disk
- space used, and the disk space remaining is also reported.
-
- The general form of the command is
-
- INDEX {/OPTIONS} {DRIVE:}{FILENAME}{.}{FILETYPE}
-
- where all of the parameters in the braces are optional. Wild card characters
- (* and ?) can be included in the file name designations. The following
- example commands, and their results, illustrate the wild character capability
- of the program.
-
-
- INDEX Directory of all files on current drive
- INDEX B: Directory of all files on drive B
- INDEX *.COM Directory of all COM files on drive B
- INDEX A??.* Directory of all three letter or less
- file names begining with the letter A
- on the current drive
- INDEX B:A*.* Directory of all files on drive B which
- begin with the letter A, regardless of
- the file name length.
-
- OPTIONS - The options which are allowed are:
-
- /R Resets the disk system before performing the
- directory search. Use this option if you
- change disks without doing a Control C.
-
- /P Directs the output to the printer rather than
- to the console.
-
- /F Outputs a form feed character (Control L) before
- printing the directory (console or printer).
-
- /T Allows a title to be input (immediately following
- the T) which will replace the DRIVE designator on
- the directory output. The maximum title length is
- 20 characters, and no spaces may be contained in
- the input title. To include spaces in the output
- title, use the underline character. The underline
- will be translated to a space before the title is
- printed. If you are using the Master Catalog Program
- and your disks have a disk name file with a dash as
- the first character, the disk name may be used as the
- title by using a /T- option. This form of the title
- option causes the INDEX program to read the disk name
- and substitute it for the normal title.
-
- /B Sets the brief mode. The size reporting for each
- individual file is suppressed. The total disk space
- used is still reported. This mode is useful for
- large directories, since more columns will fit on
- the screen.
-
- /Wn Set the output width to n, where n is a number in the
- range of 32 to 255. This command can be used to
- adjust the program for screens smaller than the
- nominal value of 80, or to set the width to a
- larger number for directories sent to the printer.
- The number of columns is automatically adjusted to
- fit the width you specify.
-
- /S Include system files in the directory listing
- (CP/M Version 2 only). System files are
- normally suppressed from the directory. This
- option allows you to display them.
-
- /M Modify the program to reset any of the above
- options to the default value. For example,
- INDEX /B/M will modify the program so that the
- brief mode is the normal state. Including the
- /B command will then cause the expanded output
- form to be used. /T-/M will cause the title to
- default to the disk name. If no disk name is
- found, the normal DRIVE A title will be used.
- You can not set up any other title as the
- default value. See the note below concerning
- this option.
-
- /V Reports the version number for the INDEX program
- you are using. Please include this version number
- when reporting any bugs or suggested improvements
- to the program.
-
- /Un Lists the directory for user number n, where n
- is a number in the range of 0 to 15
- (CP/M Version 2 only).
-
- /H Print a short help message on the console, which
- lists all of the available options.
-
-
- The options may be chained together by separating then with a slash,
- which is used as the option designator character. Chained options may appear
- in any sequence and may also include a space as a separator if desired. There
- must be at least one space following the last option and any drive or file
- designator which is included.
-
- For example, the command
-
- INDEX /R/P /F/TSYSTEM_FILES B:*.COM
-
- will reset the disk system, use a title of SYSTEM FILES, and output the
- directory of all COM files on drive B to the printer, with a leading form
- feed. A little experimentation with the options and file name wild card
- characters will give a better understanding of their operation. Note that all
- inputs may be in either lower or upper case, and are translated internally to
- upper case only, in keeping with the CP/M format. This does not include the
- titles, which may be output in upper or lower case.
-
-
- Error Messages
-
- There are three error messages which may be output by the program. These
- are:
-
- INVALID FILE NAME - Indicates that the file name specified is not a
- valid CP/M file name. This usually means that it is too long, although other
- problems can cause this error message to appear.
-
- UNRECOGNIZED OPTION IGNORED - Indicates that an option has been
- included in the command string that the program does not recognize. The error
- is ignored and all other options are still in effect.
-
- FILE ERROR DURING MODIFY - Indicates that the modify option was not
- completed successfully. This can occur if the file INDEX.COM is not found on
- the default disk, if the program and disk version numbers do not match, or if
- a disk write error occurs.
-
-
- Modify Option
-
- A word of caution if you use the Modify option. This option requires
- that the INDEX.COM program is on the default disk. If you are logged on to
- Drive A, and you issue the command B:INDEX /B/M to set the default to the
- brief mode, the program will search for a program named INDEX.COM on Drive A.
- If you do not have a second copy of the program on Drive A, an error will be
- reported and no serious consequences will result. However, if there is a file
- named INDEX.COM on Drive A, and it is not the same as the program on Drive B,
- or is a completely different program, it is possible that it will be
- destroyed. The modify command performs a check for the correct version number
- and a partial contents comparison before allowing the modify operation to be
- completed, but this is not completely foolproof. The modify command asks for
- confirmation before updating the program so if you input the modify option by
- mistake you can abort it before any harm is done.
-
- The modify command can be used to set up a default value for performance
- of a series of runs, and then be used again to restore the program to its
- original state. For example, if you want to list a series of directories on
- the printer, with a leading form feed for each printout, the command
-
- INDEX /P/F/R/M
-
- can be used to set up the desired default mode. You can then list all of the
- disks, assuming you are logged on to Drive A, using the command
-
- INDEX B:
-
- The new default values eliminate the need to list the options separately for
- each disk that you put in the B drive. Including the reset option allows the
- disk space remaining to be reported correctly, without having to input a
- Control C after each disk change.
-
- After you have printed all of the desired directories, the program output
- can be restored to the console by using the command
-
- INDEX /P/M
-
- The /P option toggles the printer flag, and since the current default was for
- printer output, this returns the default to the console. Also, since the /F
- and /R options were not reset, they are still in effect as the default mode.
- Using this technique, you can set up any available options that you desire as
- the default mode. Note that only options preceeding the /M option in the
- command line will be modified. A command of the form
-
- INDEX /B/M/P
-
- will send a brief mode directory to the printer, but only the brief mode will
- be reset as the default value. Since the /P option is after the /M option,
- the printer will be used for this run only, rather than becoming the default
- mode.
-
-
- Operating Restrictions
-
- The program is configured in a general manner and should work with any
- version of CP/M, with mini-disks, 8 inch disks, or even hard disks. The
- program has been tested with CP/M Version 1.4 and 2.2 using both single and
- double density 8 inch disks, and with Version 2.2 using mini disks and hard
- disks. Please report any errors or bugs which are detected to the author at
- the address listed above, including the INDEX version number as reported by
- the /V option, and as much detail about the system configuration and disk
- status as possible.
-
- There is one known case where file sizes may not be reported correctly.
- If you use the random write capability of CP/M Version 2, and write a file
- with holes (such as initially writing only record 10 and record 2356), the
- file size reported may not be correct. Since this type of file occurs only
- rarely (most random files are initially created sequentially) the extra code
- necessary to assure correct size reporting for them has not been included in
- the program. If you have a file of this type, the CP/M STAT command can be
- used to verify the file size.
