- 1- Syntax 2- Configuration 3- Notes
-
-
- FF is a File-Find utility derived from FINDF version 2.6. It finds all
- files matching a list of file specs on all drives, a specific drive, or a list
- of drives. All file specs are automatically made wild (that is, "A.B" becomes
- "A*.B*").
-
- Version 2.4 adds several new options, and makes all options configurable
- with ZCNFG. Uses SYSLIB4C routines, including the sort routines to make FF
- noticeably faster. Source code revised for brevity, clarity, and code optimi-
- zation. Command line syntax relaxed. Still compatible with Z3PLUS and
- DosDisk.

- Syntax FF [D: or DIR:]afn[,afn]... [d...][/o...]
-
-
- Options (d) before slash:
-
- list of drivers to scan
-
-
- Options (o) after slash:
-
- E - Exact matches only (no auto wildcarding)
-
- P - No Paging of output
-
- S - Toggle inclusion of System files based on default
- configuration (see below). System files are never
- included unless the Wheel byte is set.
- Usage - 2/2
-
- Error flag is set to 0ffh if no matching files are found, or to 1 if the
- program is aborted by the user. The number of matching files found is put in
- a register (By default, register 0 is used, but the register to be used can be
- configured. See "Configuration").
-
- If a drive or drive list is not included on the command line, the drives
- set in the drive vector are automatically scanned. The first drive, DU:, or
- DIR: reference in the list of files to seek restricts the search to that drive
- only. Others, including the optional drive list, are ignored. The drive
- specification may be part of ANY of the file specifications and is NOT limited
- to being part of the first file listed as implied by the Syntax description.
-
- The '/' before the non-drive options may be preceded by spaces, and may be
- replaced with a space. Spaces may also be present around the non-drive
- options.
-
- Output can be paged a line at a time by hitting the space bar or can be
- aborted at a page break by hitting CTRL-C.

- Configuration
-
- FF24 is configurable with ZCNFG V1.7. Defaults for the three command line
- non-drive options may be configured. The command line options then toggle
- these defaults for the duration of a single execution of FF.
-
- The list of drives (drive vector) is also configurable with ZCNFG, a major
- improvement over the former patching method.
-
- Two new default drive search vectors may be configured, one based on the
- currently logged drives and the second based on drives represented by entries
- in the current NDR (named directories). The use of named directories may be
- subject to wheel byte status. These configuration options are useful for
- ensuring system security in a RAS environment, and for helping to prevent
- access to empty floppy drives.
-
- Help screens in the configuration file give more details of the options and
- their configuration.

- FF Notes - 1/7
-
- a. Version 2.4x3 updates (1/19/91, Al Hawley):
- - Added configuration option to restrict search to named directories for
- non-wheels and within drive map constraints. Passworded directories
- are not searched.
- - Modified pagination algorithm so that the 'more' message is not issued
- when there is no more to display. This happened in previous versions
- when the display exactly filled the screen.
- - Added option to remove display of "DISC --" title lines.
- - Revised drive select option logic for functional modularity & logical
- conciseness.
- - Revised memory allocation so that the FN table and the ORDER table are
- dynamically sized to minimize memory usage.
- - Replaced filename parsing code in GETFN with a call to ZFNAME from
- Z3LIB. Removed unneccessary code and optimized code in a number of
- places. Moved all code for console display from other routines into
- the PRFILES routine. Simplified memory allocation by using Z3LIBs
- GZMTOP routine.
- FF Notes - 2/7
-
- b Version 2.4x2 updates (1/3/91, Joe Wright):
- - Provided code for Type 1 or Type 3 header. Removed code to save/
- restore current drive (not needed). Use ANDHD and ORHD from SYSLIB in
- a couple of places. Help screen to show drives like AB_D_. instead of
- ABD.
-
- c. Version 2.4x1 updates (12/30/90, Al Hawley; x1 means Beta version 1):
- - FF24 has been made configurable with ZCNFG. The current configuration
- option settings are reflected in the HELP screen. Changed the drive
- vector back to the structure used by BDOS and the ZCPR3x extended env.
- The 'human' oriented structure is no longer needed now that ZCNFG
- makes it easy and natural to modify the drive vector.
- - Most of the sorting code has been removed and replaced with calls to
- the sort routines in SYSLIB4C. These new syslib routines are MUCH
- faster than the old ones.
- - The source has been extensively edited, with a view toward better
- readability. Archaic comments were removed, and some new ones added
- where comprehension could be enhanced.
- FF Notes - 3/7
-
- - The command line syntax has been relaxed a bit to allow white space
- AFTER the drive list, and the '/' before the option field may be
- replaced with white space.
- - Included Z3PLUS code optimization from the unreleased version 2.3
- which deletes unnecessary BIOS selects.
-
- d. Version 2.2 updates (1/12/90, Howard Goldstein):
- - Exit logic modified so that nr of files found is placed in the
- register even when the program is aborted by the user. The error flag
- is set to 1 on user abort.
- - Further code crunching to get program back down to 3k.
- - Logic fixed to allow one more line on first screen of paged output.
-
- c. Version 2.1 updates (12/30/89, Gene Pizzetta):
- - Adds configuration byte to include or exclude SYStem files as the
- default. A non-zero value causes files to be included, but the byte
- will be ignored if the wheel byte is off). "S" option now toggles
- current default. Help screen modified to reflect default setting. New
- doc file includes revision history from source.
- FF Notes - 4/7
-
- d. Version 2.0 updates (11/26/89, Howard Goldstein):
- - Fixes bug which caused duplicate listing of files larger than 32
- 32 extents.
-
- e. Version 1.9 updates (03/18/89, Carson Wilson):
- - Release version. Result of general code cleanup.
-
- f. Version 1.8 updates (03/09/89, Carson Wilson):
- - Corrects check against MAXDRV byte in the environment descriptor.
- Previous code allowed one drive beyond MAXDRV. Extracts new MASK
- routine from INIT so that it can be called after any drive options are
- processed. This enforces the valid drive vector from the environment
- descriptor regardless of the setting of the MAXDRV byte.
-
- g. Version 1.7 updates (03/04/89, Carson Wilson):
- - Fixes bug which caused 'FF /' command to list all files. Only 'FF' or
- 'FF,<one or more spaces>//' (exactly) now gives help. 'FF /' or
- 'FF // ' are intrepreted as filespecs.
- FF Notes - 5/7
-
- h. Version 1.6 updates (03/02/89, Carson Wilson):
- - Changes page prompt to reflect multiple abort keys (says 'RETURN=page'
- instead of 'OTHER=page'). Help is no longer generated by a single
- slash as a parameter, allowing files beginning with '/' to be searched
- for.
-
- i. Version 1.5 updates (02/26/89, Carson Wilson):
- - Adds REG# ASCII pointer to the patch byte controlling which register
- is used to store the number of matches found. The default is zero.
- Register is changed by substituting a BINARY value from 1 to 9 at this
- storage location.
-
- j. Version 1.4 updates (02/23/89, Carson Wilson):
- - Allows abort with ^c, c, C, ^k, k, K, ^x, x, or X between pages of
- paged output. System valid drive vector is now logically ANDed with the
- table in the program.
- FF Notes - 6/7
-
- k. Version 1.41x updates (2/1/89, Howard Goldstein):
- - Fixed use of system valid drive vector. It is now logically ANDed
- with the table in the program.
-
- l. Version 1.3 updates (07/04/88, Bridger Mitchell):
- - Exits with BIOS, then BDOS drive-select.
-
- m. Version 1.2 updates (02/29/88, Bridger Mitchell):
- - Adds extended environment valid-drive vector.
-
- n. Version 1.1 updates (11/14/87, Bridger Mitchell):
- - Adds compatibility with CPM/3 and DosDisk.
- - Converts directory searches to BDOS calls, for compatibility with
- DosDisk and other BDOS emulators.
- - Removes IX register use, for compatibility with BIOS/DOS systems that
- mistakenly fail to preserve Z80 registers.
- - Adds check for presence of external environment.
- - Uses full TPA if CCP is protected. Search every valid BIOS drive
- whose bit is set in the DRVTBL (previous versions aborted on first
- invalid drive).
- FF Notes - 7/7
-
- o. Version 1.0 (03/14/88,, Jay Sage):
- - Adds DRVTBL configuration word at beginning of code which contains a
- byte for each possible drive in a system. As distributed, FF has FFFFh
- in this word so that all drives up to the max drive specified in the
- environment will be scanned.
- - Output can now be paged a line at a time by hitting the space bar or
- can be aborted at a page break by hitting ^C.
- - Enhanced syntax allows specifying a list of drives to be scanned in
- the option field.
