-
- FILT is a ZCPR3 utility that sets or expands tabs and removes several types
- of unwanted characters in ASCII text, WordStar documents, or assembler source
- code files. A summary of what the program found and what it did is presented
- upon completion.
-
- FILT is a Z'ified version of FILT7 (vs 7.0a, 5/11/86) by Irv Hoff. The
- various interactively-chosen modes have been converted into a group of logical
- command line options.
- :1
- Syntax FILT {dir:}infile {{dir:}outfile} {{/}options}
-
- Only the input filename is required. If no output filename is given, the
- default is the name of the input file. Any existing file with the same name
- in the destination directory will be renamed to filetype BAK. If no DIR or DU
- specifications are given, the current directory is assumed.
-
- As distributed, FILT defaults to ASCII text mode. Control characters
- (except carriage returns and line feeds) are removed, high-bits are reset, and
- trailing spaces and tabs are removed. Lines ending with only a line feed will
- have a carriage return inserted. All tabs are expanded to spaces and then the
- file is retabbed in 8-column increments as long as a tab will replace two or
- more spaces.
- Mode Options
-
- Only one mode option should be given. If more than one is given, the last
- one found will be used.
-
- S Source code. Quoted strings are not retabbed, but even
- single spaces are replaced by tabs until a semi-colon
- is encountered.
-
- A ASCII Text. This is the default mode (see above).
-
- W WordStar, no dot commands. Lines beginning with a period
- (dot commands) are removed, but ".pa" commands are replaced
- by form feeds and existing form feeds are retained. Soft
- carriage returns and binding spaces are converted to normal.
- Soft hyphens at the end of a line are made normal, but other
- soft hyphens (which are control characters) are removed.
-
- D WordStar, with dot commands. Identical to option W, above,
- except that lines beginning with a period (dot commands) are
- retained and ".pa" commands are not replaced by form feeds.
- Other Options
-
- T Don't use tabs. Tabs are expanded to spaces, but the
- file is not retabbed.
-
- Q Quiet mode toggle. If the ZCPR3 quiet flag is on, FILT
- defaults to quiet mode. In that case, this option puts
- FILT in verbose mode. If the quiet flag is off, this
- option puts FILT into quiet mode. In quiet mode all
- screen output is suppressed except error messages and
- the usage screen.
-
- All options can be configured as the defaults using ZCNFG and the FILTn.CFG
- file.

- Screen Display
-
- By default, an incrementing line count is displayed while FILT is working.
- The final summary screen varies depending on the current file mode. The
- default summary shows counts of the total lines in the file, original spaces,
- original tabs, current spaces, current tabs, form feeds deleted, high bits
- zeroed, control characters deleted, orphan line feeds fixed, and trailing
- spaces deleted.
-
- In WordStar mode, the display shows the number of form feeds present, since
- they are not deleted. It also adds counts for dot commands deleted (with
- option W), dot commands retained (with option D), soft carriage returns fixed,
- soft hyphens fixed, and binding spaces fixed.
-
- Under ZSDOS or ZDDOS, FILT will transfer the create date stamp from the
- source file to the new file. If the source file has no create date, the
- source file's modify date will be used instead.
-
- On error, such as an invalid directory or a file not found, FILT sets the
- program error flag to the standard codes listed in Z34ERR.LIB and invokes the
- error handler. Even a user abort via ^C invokes the error handler so a
- pending SUB or ZEX operation can be aborted.

- FILT Notes
-
- a. Vs 8.1 updates (9/30/91, Gene Pizzetta):
- - FILT did not check for ambiguous filenames (and never has), which
- could cause a small disaster. It checks now.
- - Made display of line count progress reports a configurable option.
-
- b. Vs 8.0 updates (9/10/91, Gene Pizzetta):
- - Disassembled enough to change to a relocatable file (it was easy after
- working on JUSTIFY).
- - Changed to Z80 opcodes to partially compensate for space used by add-
- itional features.
- - Replaced some routines with library routines.
- - Now allows destination directory without destination filename.
- - Changed key options to command line entry.
- - Changed some messages to make them more descriptive.
- - Added DU support, intelligent usage screen, error flag setting, error
- handler invocation, quiet mode, and ZCNFG configuration.
- - Under ZSDOS and ZDDOS file create date stamps are transferred to the
- new file.
- - Incorporates some of the code efficiencies suggested for JUSTIFY.
