TECO.DOC -- Changes from V23B(162) to V24(202)
January 1977
1.0 SUMMARY
This release of TECO is intended to support the File Daemon facility
available with TOPS-10 release 6.03. In addition, the internal file
handling routines have been modified to handle default paths, SFD's,
libraries, ERSATZ devices, and the various path switches
(/SYS,/NEW,/SCAN) in a consistent and logical manner. All bug fixes
due to SPR's have also been included.
This version fully replaces version 23B.

2.0 EXTERNAL CHANGES
2.1 File Daemon Support
TECO will now allow editing of files protected via the File Daemon.
The File Daemon bit (<400>) of the file protection is preserved in the
new source file, the .BAK file, and any ???TEC.TMP file created. Note
that in order to be able to edit files in other areas, the File Daemon
must allow access to the .BAK file and all ???TEC.TMP files, as well
as to the source file.
2.2 File Specification Arguments
TECO will now allow ERSATZ devices and SFD's in arguments to the MAKE,
TECO, ER, EW, and EB commands, as well as the "[-]" and "[,]"
constructions. More file specification syntax errors are now
detected, and several new error messages have been added to describe
these errors.
2.3 The EB and TECO Commands
On an EB or TECO command, TECO will now always put the new source file
where your command string specified. For example,
.TECO SYS:NOTICE.TXT
will now create a SYS:NOTICE.TXT and SYS:NOTICE.BAK.
If an EB command finds the source file in some area other than the one
TEC24.DOC Page 3
specified in the command string (e.g., on LIB:, by scanning up the
directory path on /SCAN, by searching SYS: on /SYS, etc.), then TECO
will read the file from the area on which it was found, and write a
new copy into the area specified in the command string. No .BAK file
will be created in this case, since the original file is still where
TECO found it.
Anytime that TECO finds a file on an area other than the one specified
in the command string, the following warning will be produced:
%File found in [path]
On an EB command, this is an indication that the copying of the file
described above is occuring. On an ER command, this is simply a
warning that the file is being read from a path other than the
user-specified one.
2.4 The MAKE Command
TECO will now accept an equal sign in a MAKE command, for example, the
command:
.MAKE A=B
is equivelent to:
.R TECO
*ERB$EWA$Y$$
An equal sign in a TECO command will be ignored, so that
.MAKE A=B
followed by
.TECO <crlf>
will edit file A normally.
3.0 KNOWN BUGS AND DEFICIENCIES
The following deficiencies have been reported for 23B and not been
corrected in 24:
1. ^C REENTER or EX$$ REENTER someitmes results in lost editing
or address checks.
2. Changing the size of the push down list causes a garbage
collection error (?GCE).
3. The value output in the [nK CORE] message is not always
correct for KI processors.
TEC24.DOC Page 4
4.0 INSTALLATION INSTRUCTIONS
TECO version 24 is installed by use of the batch control file TECO.CTL
5.0 INTERNAL CHANGES
None.
6.0 SUGGESTIONS
None.

TECO.DOC -- Changes from V23A to V23B(162)
February 1975
1.0 SUMMARY
This is a minor release of TECO and is intended to correct
deficiencies in version 23A. This version corrects many bugs related
to handling of sequenced files, ERSATZ devices and DECtape. It
eliminates several ILL MEM REF and ADDRESS CHECK problems, and
generates some new error/warning messages.
This version fully replaces version 23A.

Introduction to TECO (Software Notebook 1)
TECO Program Manual (Software Notebook 7)
2.0 EXTERNAL CHANGES
2.1 Search Commands
TECO now accepts lower case FS and FN commands. It also provides for
^S match on the first buffer character.
2.2 Line Sequence Number Processing
TECO now generates the warning message "% LINE NUMBER DETECTED IN
INPUT FILE" if the file contains line sequence numbers (LSN's) and a
/GENLSN or /SUPLSN switch has not been specified. After generating
this message TECO will output existing LSN's without change and will
insert 5 spaces and a tab at the beginning of each line which does not
contain an LSN. These blank sequence numbers may be removed by
passing the file back through TECO using the /SUPLSN switch. TECO
also recognizes SOS page marks.
TEC23B.DOC Page 6
***WARNING***
TECO is a character oriented editor and thus has inherent problems
with LSN's which are more closely related to line oriented editors.
Caution should be used when editing files with a mixture of sequenced
and unsequenced lines without /SUPLSN since for a file containing
LSN's all strings of up to five numbers initiating a line will be
treated as LSN's on output. For example where * indicates an LSN:
12345 will be output as 12345*
123 will be output as 00123*
<sp>2 will be output as
<sp><sp><sp><sp><sp>*<tab><sp>2
2.3 Altmode Conversion
TECO now uses monitor commands TTY ALTMODE and TTY NO ALTMODE to
determine if altmode conversion should take place.
2.4 Error Messages
Two new error messages have been added:
?NNQ No Numeric in Q-Register N. This will be generated if a % or Q
command is issued on a Q-Register which contains text.
?TTL Tag Too Long. This will be generated if a tag referenced by an O
command is longer than 128 characters.
2.5 Files Outside of User's PPN
TECO now conforms to the documentation in handling files outside of
the user's area. Editing of a file in another PPN (including ERSATZ
devices) by an EB or TECO command will result in reading the input
file from the specified area and writing the output file to the user's
area. For example:
.TECO SYS:FOO
will be executed as
.R TECO
*ERSYS:FOO$EWFOO$Y$$
and
*EBFOO[P,PN]$$
will be executed as
*ERFOO[P,PN]$EWFOO$$
The use of EW with a specified device or PPN now operates properly.
TEC23B.DOC Page 7
2.6 File Specification
TECO's CCL processing has been corrected to allow specification of
FILE. (dot) without an extension in a TECO or MAKE command.
3.0 KNOWN BUGS AND DEFICIENCIES
The following deficiencies have been reported for version 23 and have
not been corrected in version 23B:
1. ^C REENTER or EX$$ REENTER sometimes results in lost editing
or address checks.
2. Changing the size of the push down list causes a garbage
collection error (?GCE).
3. TECO cannot handle magtape with non-standard block size.
4. ?FUL is generated if a file on DECtape is open for both input
and output.
5. Output to device NUL: always results in a superseding
warning.
6. ?COS error is not detected for EB commands.
7. The value output in the [nK CORE] message is not always
correct for KI processors.
4.0 INSTALLATION INSTRUCTIONS
TECO version 23B is installed by use of the batch control file
TECO.CTL
5.0 INTERNAL CHANGES
TECO no longer changes BAK file protection to standard but rather
keeps the protection of the input file.
<ALTMODE> terminating a macro now returns to the next macro level
rather than reinitializing.
Garbage collection, error processing, and EW code have been corrected
to prevent ILL MEM REF and ADDRESS CHECK errors.
ET command corrected to suppress case flagging.
HP command sets bit 35 for first line sequence number in the buffer.
TEC23B.DOC Page 8
CALLI and TTCALL UUO's have been converted to standard format.
Numeric arguments are preserved across carriage return and line feed.
EH and <> commands now use the stack properly, eliminating the cause
of several garbage collection errors (?GCE).
Control flag clearing is delayed to the end of EX processing to retain
status if an error occurs during EX processing.
Logic changed to prevent infinite loop if ?EEE error occurs with 3EH
in affect.

TECO.DOC -- Changes from V23 to V23A
September 1974
1.0 SUMMARY
The purpose of this release is to add the changes necessary for
DATE-75. This is an interim release necessary to make TECO DATE-75
compatible. Another release (TECO 23B) is scheduled for the near
future. This will be a full maintenance release, incorporating all
published patches and other known corrections.
This version of TECO runs on all monitors. It has been tested on
5.07/6.01. There are no known dependencies.
TECO is documented in the Software Notebooks.
2.0 EXTERNAL CHANGES
There are no changes to the external specifications.
3.0 KNOWN BUGS AND DEFICIENCIES
Since adding DATE-75 is the only change to this version, all reported
bugs and deficiencies still exist. There are published patches for
most known bugs. These will be incorporated into TECO 23B which will
be released soon. The DOC file for version 23B will specify all
corrections made. If any bugs or deficiencies remain uncorrected in
version 23B, they will be listed in the DOC file at that time.
There is one previously unpublished bug still uncorrected which was
discovered during our testing for DATE-75: TECO destroys the date on
a file which has a creation date newer than the current date. This
can only happen if the wrong date is entered when the system is
brought up, the file is TECOed, the date is moved back to the current
date and the file is TECOed again. The cure is to TECO the file
again, thereby causing TECO to create a file with a correct date.
4.0 INSTALLATION INSTRUCTIONS
There are no changes to the installation instructions.
TEC23A.DOC Page 10
5.0 INTERNAL CHANGES
Incorporate the DATE-75 revision.
Update the control file, which builds TECO from the sources, to use
LINK-10.
