Hi all,
I'm finally starting to learn using a PDP-11 OS and one thing I'd like to
(continue to) do is working on some text. So I've starting to learn (or
cope?) with TECO. Found a TECO.SAV on some RT-11 Sigtape to run on RT-11XM.
But as the SimH console running the RT-11 is happy typing in lowercase
letters, it all goes uppercase inside of TECO.
Is there something I need to do to get lowercase working for TECO?
.SET TT: LC doesn't seem to work and doesn't seem to be needed as the RT-11
prompt happily accepts (and shows) lowercase. It's just that TECO seems to
be flipping the console or input to uppercase.
Any ideas or standard tips&tricks/hacks on using TECO on RT-11?
With kind regards,
Reiche

YEP!! On V36, try:
518ET$$
where the "$" character is the <ESC> character, of course.
The normal setting for ET is 514 which is obtained by:
ET=$$
In octal, that is 1002, so you add 4 to get 1006 and
lowercase characters are enabled. Does that work?
If you don't have V36 of TECO, it is available with the
V04.00 RT-11 binary distribution of RT-11 along with
many *.TEC files. Somewhere I have seen a manual
for V36 of TECO in text rather than PDF. If you don't
have access to the binary distribution of V04.00 of
RT-11, try to download it from classiccmp.
Are you using RT-11 for any program development?
Do you know about SDHX.SYS as the Symbolic
Debugger?
Do you ever use KED? On SimH which does not have
an internal VT100 emulator, it may be difficult to use KED.
Ersatz-11 does have VT100 emulation, so I tend to
use Ersatz-11 instead. In addition, I finally figured
out how to do repeated commands under KED, so
the only big advantage of using TECO disappeared.
The big disadvantage of TECO is the lack of support
for going back to the start of the file being edited.
KED supports going backward as well as forward.
AND if you are using the DOS variant of Ersatz-11
with a video card which supports 132 character text
lines, that is a big advantage. Otherwise, the Win32
variant of Ersatz-11 will easily support 132 character
text lines, but not in FULL SCREEN mode. Finally,
both the DOS and Win32 variants of Ersatz-11 are
able to support as many lines as your monitor can
support. I find that a big advantage with a new variant
of KED (named K42 for supporting a VT420) that
is available for users who want more than a screen
with just 24 lines.

Jerome,
Works like a charm! Thank you very much indeed!
But, I follow DEC-11-UTECA-B-D (PDP-11 TECO User Guide) and the part on the
ET flag (page 78) doesn't state anything about lower/uppercase. Only the EU
flag which I didn't get to work at all.
Where did you find this amazing piece of information?
Im usually on 60% keyboards so KEX/KED is a bit unusable for me (no keypad
or more than 80 keys for that matter). EDIT is fairly close to TECO,
though. And using EL on EDIT did work, so I just knew it had to be possible
on TECO ;)

I thought I found it in my TECO manual - which is probably buried
at the moment. Otherwise, it would have been by reading the source
code.
In any case, I am very pleased that you let me know my
reply was helpful.
Do you have V36 of TECO? One of the other flags will
provide the version number.

TECO is really powerful. I think TECO can support
a full screen editor like KED by using the *.TEC files,
but I never managed. Since your system does not have
a keyboard with a keypad, KED is out. As for KEX,
which I used for a long time, especially when I used
a system job under RT-11, the RT-11 documentation
is extremely misleading. At this point, I no longer use
KEX except maybe just to test the variant which supports
a VT420 with more than 24 lines. The working memory
and the size of the cut / paste buffer is so much bigger
when using KED that using KEX is out of the question.
I can provide details of why if anyone is interested.
When a background job is running, just use VBGEXE
to start KED and all 64 KB are available. The special
code used to tell the user when KED is "...working"
requires a data buffer in Low Memory which VBGEXE
supports.
When I run as a system job, the choice is to either use
VBGEXE to support that data buffer in Low Memory
or use a customized variant of KED which uses code
that internally supports the allocation of that data buffer
in Low Memory. The disadvantage of using VBGEXE
to initiate KED as a system job is the need for about
1185 words of Low Memory while the advantage is
KED has 64 KB for code and data. The advantage
of the customized variant of KED is the requirement
of as little as 384 words of Low Memory while the
disadvantage is only 56 KB for code and data. The
loss of 8 KB for data was a small cost for reducing
the Low Memory to 384 words since 99% of the time,
I initiate at least FOUR KED system jobs, although
I have yet to add the code to "SRUN" to dispense
with the extra chunk of Low Memory (an extra
32 words) when it is not needed. Thus far, the most
I have done is to set a BPT in that code and modify
the number of words requested, so I know it can be
done. But saving 3072 words of Low Memory
( [ 1185 - 417 ] * 4 ) is a huge advantage. The 417
words are what SRUN requests at the moment until
the code to eliminate the extra chunk is added.

Glad to know it works for you.
Which version of TECO are you using? V36?
Do you at least have the binary distribution of V05.03
of RT-11 which most individuals believe is legal to run
under SimH? V05.03 has most of the really nice features
of RT-11 which are found in the most recent version
except perhaps Y2K support - which many users of RT-11
(especially hobby users who do not need dates in the first
place) do not care about. The most important is the support
for MSCP partitions so that large disk drives of more than
32 MB can be used. While the DEC version of V05.03 of
RT-11 can't boot non-zero MSCP partitions, with V05.02
of RT-11, the maximum number of blocks easily available to
a user for an MSCP drive was 65535 blocks.

Jerome,
Would you mind me taking (all of) this up off-list?
