- 1988 No. 19 (Utilities)
-
-
- Purpose: A small, full-screen editor for line-oriented files of up to
- 64K in length that supports scrolling, cut, copy, paste, and printing
- operations, and permits entry of all members of the IBM character set.
-
- Format: TED [filespec]
-
- Remarks: TED will open and read a file whose name (and path, if required)
- are supplied initially. If no filespec is provided it will open a new file and
- prompt for a filename when the Save and Exit command (F7) is given. The
- original of a modified file is saved with a .BAK extension. The Abort command
- (F1), when verified, abandons any modifications and leaves the original file
- intact.
-
- Lines may be of any length, and each must be terminated by pressing
- Enter. Lines longer than the screen width display a diamond in the rightmost
- column. Offscreen characters (up to 248 columns) may be viewed by using the
- Ctrl-<arrow> keys. Lines may be broken by pressing Enter at any point, and may
- be conflated by pressing Delete at the line end.
-
- A block of text is defined by toggling on the Mark command (F4) and
- moving the cursor with the arrow keys. The Marked area is shown in inverse
- video. Pressing F3 prints the blocked text; F5 (Cut) removes it to a buffer
- from which it can be Pasted (F6) at any point where the cursor is located. The
- paste buffer remains intact until another section is marked and cut.
-
- Pressing F8 deletes to the end of a line; F9 deletes the entire line.
- F10 restores the most recent deletion of F8 or F9. The Undo command (F2)
- restores letters deleted by the Delete (but not by the Backspace) key if the
- cursor has not been moved.
-
- The Home and End keys move the cursor to the beginning and end of the
- current screen line; the Tab key moves to the next column evenly divisible by
- eight. Text is entered in Insert mode by default; pressing the Insert key
- toggles to overstrike mode. TED configures itself to the display in use and
- supports EGA and VGA text modes other than the standard 80 columns by 25 rows.
- PgUp and PgDn scroll the file by the number of rows displayed, minus 5.
- Ctrl-PgUp and Ctrl-PgDn move to the top and bottom of the file.
-
- Any character in the IBM set can be entered by pressing the Alt key,
- typing its ASCII value on the numeric keypad, then releasing the Alt key.
