AAREADME.TXT
This directory contains TECO-C, a version of TECO written in C.
It was written in C so the author could move comfortably from VAX/VMS
to various other machines, including MicroVaxes, which couldn't execute
TECO-11 prior to VMS 5.0 because they don't support PDP-11 compatibility
mode. TECO32, distributed with v5.0, solved this problem.
TECO-C is meant to be a complete implementation of TECO as defined
by the Standard TECO User's Guide, which is in file TECO.DOC. There is no
manual for TECO-C itself, but the Standard TECO manual was the specification
for TECO-C, so it serves as an excellent manual. TECO-C departs from the
Standard manual in only a few places (like no video mode), listed in file
PROBLEMS.TXT. There is quick-and-dirty "wall chart" of all TECO commands
in file WCHART.TXT.
This version of TECO-C runs under VMX/VMS, MS-DOS, AmigaDOS and Unix
(SunOS, Ultrix and System V on a Data General Aviion). If you find bugs or
have any comments about TECO-C, please contact

The following sections describe how to use or build TECO-C for
different environments. The command line syntax is the same as the syntax
for TECO-11 command lines.
###########################################################################
U N D E R V A X / V M S
TECO-C was mostly developed under VAX/VMS. It compiles and links
using VAX C 3.1 under VMS version 5.3.
To set up: inspect and modify ZVLOGIN.COM and then add it to your
LOGIN.COM
To compile: inspect/edit ZVBLD.COM, then SUBMIT it
To link: use the "LT" command (defined in ZVLOGIN.COM)
To run: inspect/edit the symbol definitions in ZVLOGIN.COM
Note: TECO-C uses the same command line syntax as TECO32
###########################################################################
U N D E R M S - D O S
TECO-C compiles/links under Turbo C v2.00 under MS-DOS 4.01 and
Concurrent DOS 386 v3.0.
To build: run MAKE on MAKEFILE.TC. to build TECO from scratch say:
"make -fmakefile.tc -DALL". see MAKEFILE.TC for other make
-D options. also see MAKETECO.BAT.
To run: use TECO.BAT to edit a file or MUNG.BAT to run a macro,
for example: TECO filename.
###########################################################################
U N D E R U N I X
To compile and link: use the make utility on "makefile.sun" (for SunOS) or
"makefile.ulx" (for Ultrix) or "makefile.dg" (for System V Unix
on a Data General Aviion).
To run: define aliases and environment variables in your .cshrc file.
Here's an example, assuming my initialization file is named
.tecorc and it's in my home directory, and my macros are in a
directory named tecoc under my main directory. You'll have to
change the directory names, of course.
setenv TEC_INIT \$/home/sol/siemsen/.tecorc
setenv TEC_LIBRARY /home/sol/siemsen/tecoc/
alias te '/home/sol/siemsen/tecoc/tecoc teco -nocreate'
alias mung '/home/sol/siemsen/tecoc/tecoc mung'
alias tma '/home/sol/siemsen/tecoc/tecoc make'
After doing this, "te" runs tecoc.
Unix Command line
---- ------- ----
To make Unix users more comfortable, TECO-C uses Unix-like options syntax
instead of the familiar "/" style used under VAX/VMS. The options can be
abbreviated. They are (optional characters in square brackets):
-in[spect]
-noc[reate]
-noi[ni]
-nom[emory]
-sc[roll]
-scroll:nnn:SEEALL
do nnn,7:W and 1,3:W
-nop[age]
Don't separate input into pages. Instead, treat form feeds as
normal characters.
+nnn
where nnn is any number of digits. Go to line number nnn and set
nopage. Note this uses the UNIX end of line convention for use with
cc output &c. The non-unix line termination will still be used for
nL and other intrinsic TECO commands, this just controls the
starting line AT INVOCATION.
EZ Mode Control Flag
-- ---- ------- ----
To add functionality, TECO-C is sensitive to bits in an extra mode control
flag in addition to the standard ones. Bits in the EZ mode control flag are
used in different ways by different operating systems. Under Unix, bits in
the flag have the following meanings:
1 Mark Henderson, who did much of the Unix port, likes the way
VAX/VMS keeps versions of files. VMS appends a semicolon followed
by a version number to files, and has the PURGE command to clean
out old versions of files. If this bit is off, TECO-C will handle
file version numbers, appending the appropriate version number to
file names. Mark supplied a "purge" program (distributed with TECO-C)
for users of this feature. Setting this flag turns off the feature,
to make TECO-C function as expected by the average Unix user. This
flag is set by default.
8 I don't know what this flag does. It only makes sense when TECO-C
is compiled with CURSES support.
16 If set, when it's time to beep, use an audio beep, and if it fails,
then try a video flash. If clear, try a video flash, and if it
fails, use an audio beep. This bit works only if TECO-C was compiled
with CURSES support. This bit is off by default.
32 If set, and split screen scrolling mode is on (see the 7:W command),
TECO-C puts a line between the upper and lower scrolling regions.
If off, don't display a line. This bit works only if TECO-C was
compiled with CURSES support. This bit is off by default.
128 If set, don't stop on form feeds when reading. If clear, a form
fed in the input stream stops the read (the standard TECO style).
This bit is off by default.
256 If set, use Unix-style newline terminators. This means when files
are read in, carriage-returns are not added to the end of lines,
and when the user types the RETURN key, only a newline is entered
into the command line (usually a carriage-return/line-feed pair is
entered). Old macros (and old TECO users) may get confused if this
bit is set, but it's required if CURSES support is compiled into
TECO-C.
2048 If set, use a bottom-tee symbol instead of a diamond to indicate
the end-of-buffer. This bit works only if TECO-C was compiled with
CURSES support. This bit is off by default.
8192 If set, don't show CR in SCROLL mode (like standard TECO). If clear,
show CR (a graphics character indicating a carriage return) when in
SCROLL mode. This bit works only if TECO-C was compiled with CURSES
support. This bit is on by default.
Filename Memory
-------- ------
TECO tries to remember the last file edited by TECO, so that after you've
edited a file once, you can re-edit without having to type the file name
on the command line. TECO-C implements this under Unix by writing and reading
files named /tmp/tecoxxx.tmp, where "xxx" is the process id of the parent
process.
NOTE: There is another TECO in C, written by Matt Fichtenbaum, which
runs under Unix. It is part of the DECUS TECO Collection. Contact Pete
Siemsen at the above address for a copy.

To compile and link: see makefile.ami, (note: it needs tecoc.lnk)
Comments from the author of the Amiga code:
I've completed my TECOC port to the Amiga. It has been tested on an
Amiga 1000 under AmigaDOS 1.3.2. My system configuration is:
68000 microprocessor
2.5 megs memory
80 meg hard drive
Old Amiga chip set
SAS Institute C for the Amiga version 5.10
TECO-C runs in the CLI window it was started from, and it should run
over a terminal hooked to an Amiga serial port as well.
Adding 'W' command stuff would probably best be done by one of the
termcap ports to the Amiga, however, TECO would have to handle
SIGWINCH-like events, unless it is modified to open it's own window of
a particular size without a resizing gadget. It wouldn't be to hard to
write a terminal driver for Amiga windows using hard-coded escape
sequences either, but then that would lose over a serial port.
EzFlag
------
The EZ flag is system-dependent. Under AmigaDOS, bits in the flag have the
following meanings:
128 If set, don't stop on form feeds when reading. If clear, a form
fed in the input stream stops the read (the standard TECO style).
This bit os off by default.
256 If set, use Unix-style newline terminators. This means when files
are read in, carriage-returns are not added to the end of lines,
and when the user types the RETURN key, only a newline is entered
into the command line (usually a carriage-return/line-feed pair is
entered). Old macros (and old TECO users) may get confused if this
bit is set, but it's required if CURSES support is compiled into
TECO-C.

I maintain the DECUS TECO Collection, a bunch of stuff relating to
TECO. It includes sources for DEC's TECO-11 v39, three TECOs written in C,
including ones for VAX/VMS, MS-DOS, SunOS (Unix) and Ultrix, the current
Standard TECO manual, two EMACs-like macro packages and LOTS of macros.
I you have something that you feel should be included in this
collection, or if you would like to improve the software, please contact
me at the above address.
