NOTES

(1]
[2]
[3]

Re-executes last TECO command. Ignores
filespec2, if present on previous command

/TECO switch not necessary if SET EDITOR
TECO command has been previously specified
SFD’s allowed in TOPS-10

[4]

Re-executes last MAKE command

(5]

TECO under RSTS/E and OS/8 requires two

s @ is not an immediate mode
command in RT-11 and RSX-11

(6]

TECO-10 types the last 10 characters of the
command string before the error occurred
Not an immediate mode command in TECO-10

(execution is deferred until next wake-up character). In TECO-8, the immediate mode
command

(8]

is the same as *Z

Two @ s may be necessary on systems that
support type-ahead

[9]

Only if feature is enabled in the operating system

[10]

TECO-10 closes any previous file.

[11]

Not in RSTS. TECO-10 does not require $

[12]

On TECO-11, 4+ C in a macro returns control to
TECOQO's prompt

[13]

[14]
[15]

TECO-10 has no general octal radix mode
In TECO-10, a space between two numbers also
acts as an addition

TECO-10 prints signed result; TECO-8 and
TECO-11 print unsigned result

[16]

On TECO-10, nA is the same as OA

[17]

Must immediately follow search in TECO-11

[18]

Cannot jump to before start of current iteration
in TECO-8 or TECO-11

TECO-10 stores either text or numeric data (but
not both simultaneously) in a single area within
the Q-register
Same as 1%q in TECO-10
Arguments ““pass through’’ this command in

TECO-11
On TECO-10, no case flagging occurs if the
terminal supports lower case, regardless of

state of EU flag

[23]

TECO-10 uses only bit value 1, TECO-8 uses only
bit values 1, 2, and 8

[24]

In TECO-10, 1O must be followed by a digit
string and the octal radix mode applies only to
this string

TECO-10 allows begin of buffer, ., $, and % to
match

Cannot quote $ on TECO-10

NOTES

NOVICE SUBSET OF TECO
These commands allow you to do most common editing

jobs on all versions of TECO.
MAKE file

Creates a new file (under RT-11, use.

TECO file

Edits an existing file (under RT-11,
use EDIT command)

CREATE command)

Moves pointer to beginning of buffer
ZJ

Moves pointer to end of buffer

Advances pointer to beginning of next

nL
-nL

Advances pointer n lines
Moves pointer back n lines

Moves pointer to beginning of current

Advances pointer across one

Advances pointer across n characters

line

line
character
-nC

Moves pointer backwards across n
characters

Types text from current pointer
position to end of current line
Types n lines on terminal

Types entire content of text buffer

OTT

Types current line

ltext$

Inserts text before current poiriter
position

Deletes text from current pointer
position to end of line

nkK

Deletes n lines of text

Deletes entire content of text buffer
Deletes the character following the

pointer

Deletes n characters after the pointer
Deletes n characters before the pointer
Outputs the current page and reads in
the next page

Executes the P command n times

Append the next input page to the
end of the buffer
EX

Stext$

Moves the remainder of the input file
to the output file, closes the output
file, and exits from TECO
Beginning at the current pointer position, searches for the specified text on
the current page. The buffer pointer
is positioned after the specified text if
it is found. If the text is not found, an
error message is given and the buffer
pointer is left at the beginning of the
page

Ntext$

FStext1$text2$

Same as Stext$ except that the search
continues across page boundaries, if
necessary, until the string or the end
of the input file is encountered
Searches for text1 and, if found,
replaces it with text2
