Blast from the past: SPIT - A print formatting utility from 1987

SPIT - A print formatter for the PC
Author: Charles E. Kindel, Jr. (tigger)
Started: July 18, 1987
Version: 1.53
SYNOPIS
spit [/ln /pn /w /cn /in /hs /fs /o<file> /s] <filename.ext>
/ln : where n is the number of lines to be printed on each page.
Must be < (PageLen - 4). Default is 56 lines.
/pn : where n is the page length in lines. Default is 66 lines.
/w : sets compressed mode on IBM/EPSON dot matrix printers. Sets the
number of columns to 132. Should come before the /c option on
the command line.
/cn : where n is the number of columns. Lines read in longer than
n will be truncated. The /i option reduces n by the number
of columns to indent. Lines longer than n will be truncated.
Default for column is 80. Use /w for 132 columns on IBM/EPSON
dot matrix printers.
/in : where n is the number of columns to indent from the left margin.
This option reduces the total number of columns specified with
the /c and /w options.
/s : Single sheet option. Pauses before printing each page.
/o<file> : Where <file> is an output filename. Default is the standard
print device (PRN).
DESCRIPTION
"spit" spits a file with page breaks, headers, footers, page numbers,
and indentation out on the printer. It supports the IBM/EPSON dot matrix
printers, and uses compressed and double strike characters.
In a nutshell spit just echo's characters to the output device (the
printer or a file). But it counts lines and sends headers, footers,
and page breaks. If a line is longer than the number of columns
specified (default is 80) that line is truncated.
The headers and footers mentioned above are printed in double strike.
The last page of the printout will have the string "end of file" in the
footer.
LIMITATIONS
The program will work on IBM/EPSON compatible dot matrix printers only.
It is possible to change the #defines below to match your printer.
Does not support color on 43line EGAs. Until Borland supplies a CONIO
library that supports 43line egas this program will be monochrome.
REVISIONS
DATE VER NAME CHANGE
July 18, 1987 1.00 Kindel Original
July 20, 1987 1.20 Kindel Fixed bugs, Incuded "revised on"
Added several features.
July 26, 1987 1.21 Kindel Fixed footer on last page.
Aug 31, 1987 1.40 Kindel Added Formfeed support, fixed footers
again.
Oct 11, 1987 1.41 Kindel Lines that were longer than MaxCols
previously were thought to be truncated
But were really being treated as new
lines. Fixed line counting to account
for this. Made messages go to STDOUT
instead of STDERR.
June 1, 1988 1.42 Kindel Added color.
June 1, 1988 1.50 Kindel Set up for wildcard support. As soon
as TC is modified to automatically
expand wildcards, the code I've added
will handle multiple files. For now, the
user can type more than one file on the
command line.
Made the filename formatting in
the header more robust.
Commented out color until CONIO supports
43 line EGA.
Implemented single sheet option.
Fixed problem with Compressed not
turning off.
June 2, 1988 1.51 Kindel Added "expand wild" to the TC libraries
thus this program will automatically
expand wildcards.
Fixed problem with options: before,
only lower case options were recongized
now it will recognize both upper and
lower case.
July 17, 1988 1.52 Kindel After using CLIBFIX to update the libraries
to handle 43 and 50 lines, fixed spit to use
these features.
Nov 15, 1988 1.53 Kindel Update to TC 2.0
