| [12] | On TECO-11, ^C in a macro returns control to TECO's prompt |
| [13] | TECO-10 has no general octal radix mode |
| [14] | In TECO-10, a space between two numbers also acts as an addition |
| [15] | TECO-10 prints signed result; TECO-8 and TECO-11 print unsigned result |
| [16] | On TECO-10, nA is the same as 0A |
| [17] | Must immediately follow search in TECO-11 |
| [18] | Cannot jump to before start of current iteration in TECO-8 or TECO-11 |
| [19] | TECO-10 stores either text or numeric data (but not both simultaneously) in a single area within the Q-register |
| [20] | Same as 1%q in TECO-10 |
| [21] | Arguments "pass through" this command in TECO-11 |
| [22] | 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, ^O must be followed by a digit string and the octal radix mode applies only to this string |
| [25] | TECO-10 allows begin of buffer,.,$, and % to match |
| [26] | Cannot quote $ on TECO-10 |
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 CREATE command) |
| TECO file | Edits an existing file (under RT-11, use EDIT command) |
| J | Moves pointer to beginning of buffer |
| ZJ | Moves pointer to end of buffer |
| L | Advances pointer to beginning of next line |
| nL | Advances pointer n lines |
| -nL | Moves pointer back n lines |
| 0L | Moves pointer to beginning of current line |
| C | Advances pointer across one character |
| nC | Advances pointer across n characters |
| -nC | Moves pointer backwards across n characters |
| T | Types text from current pointer position to end of current line |
| nT | Types n lines on terminal |
| HT | Types entire content of text buffer |
| 0TT | Types current line |
| Itext$ | Inserts text before current pointer position |
| K | Deletes text from current pointer position to end of line |
| nK | Deletes n lines of text |
| HK | Deletes entire content of text buffer |
| D | Deletes the character following the pointer |
| nD | Deletes n characters after the pointer |
| -nD | Deletes n characters before the pointer |
| P | Outputs the current page and reads in the next page |
| nP | Executes the P command n times |
| A | Append the next input page to the end of the buffer |
| EX | Moves the remainder of the input file to the output file, closes the output file, and exits from TECO |
| Stext$ | 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$ | 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 |
| FStext1$text2$ | Searches for text1 and, if found, replaces it with text2 |
