tde, the Thomson-Davis Editor Version 1.5 April 1, 1992 Frank Davis Description: tde is a simple multi-file/multi-window text editor. It is suitable for editing batch files, text files, and various computer language source code files. The only limit on the number and size of files that tde can handle is the amount of conventional memory. Likewise, the only limit on the number of windows is the amount of conventional memory. There is no preset maximum number of files or windows that may be open at any one time. Usage: At the command line type: tde [file name(s)] For example: tde tde foo.bar tde c:\c60\tde\main.c tde *.c \qc25\tde\*.h tde foo.bar foobar f* foo.* f??b?? If you don't enter a file name at the command line, tde will prompt you for a file name. If the file does not exist, tde starts out with an empty file with the file name you just entered. tde will handle files as large 465k. If you try to edit a file larger than 465k, only the first portion of the file is loaded into tde. With DOS 5.0, you can edit files as large as 515k if you load DOS high. tde will handle lines as long as 255 characters. Only the first 255 characters of long lines are handled - long lines are not truncated. Starting with tde version 1.3, you can enter multiple file names on the command line. File names may even have wild card characters, * or ?, embedded in the name. To bring in those files, press the EditNextFile key, Alt-F4 in the distribution version, at any time. There are no restrictions on how you enter file names, just put any combination of valid file names on the line and tde will load the next file when Alt+F4 is pressed. New features in tde 1.5 include : Ruler = @R Block trim trailing = @T User defined macros: Record macro = @F3 Save macros to file = #F1 Load macros from file = #F3 Clear macro buffer = ^ESC Critical error handler If by accident you forget to put a diskette in a floppy drive and try to save a file on that diskette or if you forget to turn on the printer before printing a block or file, a critical error occurs. That kind of error is the infamous Abort, Retry, Ignore thing. A routine was written to give some information on the kind and the location of those errors when they occur. The tde critical error handler gives you all kinds of info and then prompts you for a response. The timeout for critical errors varies quite a bit. Some timeouts may take a couple of minutes. When I "work" at the USDA, I often need to create or massage formatted data files. Also, a lot of engineers and scientists at the USDA program in FORTRAN and the source code needs to be in a certain format. When working with those types of files, it is really useful to have a ruler that explicitly shows which column the cursor is in. The new ruler in tde shows margins, column numbers, and a column pointer. A feature that should really prove useful is a simple macro record and playback function. To use it, press the macro record key and the key you want to assign the recording to. Then, enter the keystrokes that you want recorded. When you get through, press the record macro key to turn recording off. Whenever you press the key that was assigned the recording, it plays back the keystrokes just like they were entered from the keyboard. Any unused function key may be assigned a recording. It does not playback answers to prompts. A typical American, I can only speak and write English and not very good, either, my ownself. For those who are multilingual and speak more than one language, you may use macros to assign any ASCII or Extended ASCII character to unused function keys. Some languages use characters with marks like the cedilla, dieresis, acute, circumflex, grave, breve, tilde, etc... Just use the macro record function and assign the characters as needed. For example, the Alt+A key could be assigned to Ä or the Control+E key could be assigned to é. The ALT + SHIFT + alphabet characters have been added to version 1.4 for just this purpose. New features in tde 1.4 include : Split screen vertically = F8 Number box block = Alt+N Directory list = Alt+F1 Also added in tdecfg was a choice of cursor styles and a switch for .bak files. Both of those options are in the mode section of tdecfg. Features in tde 1.3 include : User configurable color cursor line Cursor sync. - useful for comparing files = Ctrl+F1 Horizontal char left = Shift+Ctrl+left Horizontal char right = Shift+Ctrl+right BackTab function = Shift+tab Added support for stream blocks = Alt+X Added toggle for writing Control Z at eof = Alt+Z Word Wrap toggle = Alt+V Set Left margin = Ctrl+F6 Set Right margin = Ctrl+F7 Set Paragraph margin = Ctrl+F8 Left justify = Alt+F8 Right justify = Alt+F9 Center justify = Alt+F10 Format paragraph = Alt+F7 or Ctrl+B Format text (format forward from cursor) = Alt+N RepeatFindForward2 = Alt+F5 RepeatFindBackward2 = ALt+F6 Toggle eol (end of line) display = Ctrl+F2 Added toggle for writing <CR><LF> or <LF> at eol = Ctrl+F3 Toggle trimming trailing space at eol = Ctrl+F4 Block to upper case = Alt+< Block to lower case = Alt+> Block strip hi bit - useful with WordStar files = Alt+? SetMarker1 = Alt+1! ... ... SetMarker3 = Alt+3( GotoMarker1 = Shift+Alt+1! ... ... GotoMarker3 = Shift+Alt+3) Set file attributes = Alt+F2 Allow multi-file names at command line, eg. = Alt+F4 tde *.c tde *.bat *.doc tde *.bat my.doc other.doc *.dat <CR><LF> or <LF> at eol The functions that write to files were expanded to allow you to choose whether you want to write a <CR><LF> or just a <LF> at the end of line. Some programs look for just the <LF> at the eol while others want the <CR><LF> pair at the eol. tde has no trouble reading either style but allows you to specify the output style. You may change the style by pressing the ToggleCRLF function key or by using tdecfg to set the default. Here's a little diagram that may help explain the new functions better than I can write. Output Input tde's internal representation Toggle files ┌────────────────────────────┐ files with │ tde will read files with │ with <CR><LF> ====>│ lines that terminate in │ =====> <CR><LF> at eol │ either <CR><LF> or <LF>. │ at eol │ │ │ │ files │ Internally, all lines end │ files with │ with the <LF> character. │ with <LF> =====>│ │ =====> <LF> at eol └────────────────────────────┘ at eol The default file function assignments write the <CR><LF> pair at the eol. Please feel free to change the function key assignments to suit your needs.

You will have two keys depressed together at the same time. The function assigned to that key combination will be executed as soon as the second key is pressed. You may release the keys in any order you choose.

Grey cursor keys Keypad keys Up - move cursor up Home - toggle col 1 & beg of line Down - move cursor down ^Home - first line in window Left - move cursor left Pg Up - page up Right - move cursor right ^Pg Up - goto first page in file ^Up - scroll screen up Center - move to center of window ^Down - scroll screen down ^Center - line to center of window ^Left - cursor to previous word End - last character in line ^Right - cursor to next word ^End - last line in window @Up - fixed cursor, text scroll up Pg Dn - page down @Down - fixed cursor, text scroll down ^Pg Dn - goto last page in file @Left - horizontal char left Ins - toggle insert mode @Right - horizontal char right Del - delete character @PgUp - horizontal page left ^Del - stream delete character @PgDn - horizontal page right Grey - - scroll screen up ^#Left - horizontal char left Grey + - scroll screen down ^#Right - horizontal char right ^Grey - - fixed scroll screen up ^Grey + - fixed scroll screen down Enter - Insert line and move down #Enter - 1st char in next line Note: The Alt+Cursor keys are not ^Enter - column 1 in next line available on 83/84 key keyboards. Pressing the Alt + a number key on the keypad generates a character code and not a cursor movement command. FYI, the Alt+keypad is the method for entering any ASCII or Extended ASCII character into the text file. Function Keys: I tried to use some logical order when I assigned functions to the function keys. I use a 101 keyboard most of the time, so it should be easy to see the logical function grouping with it. The function keys on a 101 keyboard are placed along the top of the keyboard. Functions are arranged as follows: Help File Find & Window Functions Search/Replace Commands F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F1 = Instantaneous Help @F1 = Directory List List the contents of a directory or matching files. At the prompt, press enter to list all files in the current directory or enter any valid subdirectory name, file name, or wild card characters. You don't have to put a *.* at the end of a subdirectory name; the directory list function adds those wild card characters to subdirectory names as a default. A '\' is added to the end of subdirectory names in the file list. To list the files in other directories, just move the cursor to the desired subdirectory name and press enter. When you see ..\ in the directory list, the double periods represent the parent of the current directory. The .\ represents the current directory. You may move up and down the directory tree by selecting the parent or childrens of the current directory. File Functions: F2 = Save file Saves all changes made to file. Existing file is overwritten by the new file. It does not prompt for a new file name - automatically assumes you want to overwrite the old file. There is no way to get back the contents of the original file if you use this function. F3 = Quit file Abandons any changes made in the file and closes or kicks the file out of the current window. If you are editing multiple files or have multiple windows, tde searches for any invisible files to display in the current window. If no invisible windows are found, tde combines windows. If this is the only file being edited, F3 quits tde. If you made any changes to the file, it asks you if you want to abandon them. You can create an invisible window when you load in a file over the current file. Nothing happens to the invisible file or window - you just can't see it. F4 = File (save and quit) This function is a combination of Save and Quit (F2 & F3 above). #F2 = Save as If you don't want to overwrite the original file but you want to save the contents of the current file, you may save the file under a different file name. This function prompts you for a file name to save the changes (press escape to abort). #F4 = Edit new file To bring another file into the editor, use this function. It loads the file into the current window and previous window becomes invisible. You can even load several copies of the same file. I like this because I often need to refer back to the original unchanged file. Each time you load a file, it is treated as a different file. Be careful when you have several copies of one file open. Don't forget which version of the file you want to keep. If worse comes to worse you always quit. @F2 = Set file attributes Change the attributes of a file. Attributes are: A = Archive, S = System, H = Hidden, R = Read-Only. You can change the attributes of a file so that read-only files can be edited. To edit a read-only file: 1) edit the file, 2) change the file attributes to archive, 3) save the changes made in the file, 4) change the file attributes back to read-only. @F4 = Edit next file If you type mutliple file names or type wildcard characters on the command line, press this key to bring in the next file or the next matching file into the editor. You may press this key at any time. When I use this feature, I usually split the screen and load the next file into a window. This feature is useful when you need to look in several files for a piece of code or if you know that you are going to edit several files at the same time. Macros: @F3 = Macro record This key toggles macro recording off and on. A flashing "Recording" is displayed in the lite bar, so it shouldn't be too difficult to tell when record is on. This function assigns a keystroke or a series of keystrokes to an unused function key. Any ASCII, Extended ASCII, or function key can be part of the macro with a couple of exceptions: 1) recursion is not supported because there is no way to break out of a macro, 2) the RecordMacro, SaveMacro, LoadMacro, and ClearAllMacros functions cannot be a part of the series. As far as I know, those are the only two exceptions. The macro utility does not playback answers to prompts. There is room for 1024 keystrokes in the macro buffer. There are no restrictions on the length of a single macro. If you want, you may define one macro that contains 1024 keystrokes. When tde terminates, all macros definitions disappear. Macro definitions are temporary. If you want to reuse macros that are defined during an editing session, they need to be saved before you exit tde. Use the load macro command to bring in a previously saved macro file. For those who want to permanently assign characters or macros to unused function keys, create your favorite macros and save them to disk. Then, use tdecfg, option 5, to permanently save the macro file in tde. Your favorite macros will be available anytime you use tde. #F1 = Save macro file Saves all macro definitions to a file. tde prompts for the macro file name. #F3 = Load macro file Prompts for a search pattern or file name. I can never remember macro file or path names, so this function uses a file pick list. ^ESC = Clear macros Resets or clears all macros. Find and Search/Replace: ^F5 = Toggle search case Most of the time I don't care about matching the case of the search pattern. The default in tde is to ignore search case. If you want to consider the search case, press this key to toggle the case flag. The state of the flag is displayed, in English, in the lite bar at the bottom of the screen. You can toggle the case of the search flag at any time, even after you define the search pattern. #F5 = find forward To define the search pattern, use this function. It prompts you for the search pattern. The pattern is defined (even across files) until changed. If the pattern is not found, an information message is displayed at the bottom of the current window. #F6 = find backward Same as find forward except search backward in file. F5 = Repeat find forward Once the search pattern has been defined (Shift F5 or Shift F6), you can press this key at any time in any file to find the next occurrence of pattern. I decided to use two sets of functions to perform searches. Once I found a pattern, I might do some editing and then find the next occurrence. I hate to define the search pattern over and over or set the search direction over and over. This function does a wrap search - when it reaches the eof it starts over at the beginning of the file. F6 = Repeat find backward Like repeat find forward, you can press this key at anytime once the search pattern has been defined. @F5 = Repeat find forward2 Like F5 except the cursor is not repositioned to the middle of the screen. @F6 = Repeat find backward2 Like F6 except the cursor is not repositioned to the middle of the screen. #F7 = Search/Replace forward This function prompts you for the search pattern and the replacement text. If you want to match the search case, remember to toggle the search flag (which can be done at any time). You can either do prompt or no prompt replacing. Regardless of prompt or noprompt replacing, this function actually moves the cursor to the pattern and displays it on the screen and replaces the text. If you are using tde on a slow machine, you can see the search/replace taking place. I implemented the function this way because I just like to see what the search/replace function is doing. The Search/Replace functions WRAP around the file. tde will prompt you when this occurs. #F8 = Search/Replace backward Same as search/replace forward except backwards. Window Functions: F8 = Split window vertically Splits the screen at the current cursor location. The current file is displayed in multiple windows. Changes to a file are displayed in all windows opened to the same copy of that file. You can also see any marked blocks in the same copy of the file in different windows. There has to be at least 15 columns in any window, so the number of visible windows is limited by the display screen. F9 = Split window horizontally Splits the screen at the current cursor location. The current file is displayed in multiple windows. Changes to a file are displayed in all windows opened to the same copy of that file. You can also see any marked blocks in the same copy of the file in different windows. There has to be at least 1 text line in any window, so the number of visible windows is limited by the display screen. Displaying one line in a file is not all that helpful but the ability to do so is there. #F9 = Resize window Sometimes there is a need to concentrate on the contents of one window. You can change the size of the current window by using this function. Use the up and down arrow keys to adjust the current window to desired size. When you reach the desired size, press either the ESC key or the Return key to make the change permanent (the message on the screen says press ESC but either Return or ESC will do). Changing the size of the top window is not allowed. ^F9 = Zoom window Makes the current window fill the whole screen. If the current window already fills the screen then nothing is done. All windows on the screen when the zoom command is executed are expanded to full size. Additionally, all windows except the current window become invisible. F10 = Next window If more than one window is displayed, you can press one key to move to the next open window. #F10 = Previous window Move to previous window - opposite of next window. ^F10 = Next Hidden Window Displays "hidden" or "invisible" windows in the same place as the current window. The current window then becomes invisible. Block Commands: Block operations can be done within or between files. If you mark a block in one file, just move the cursor to the desired location in the same or other file and do the block operation. Operations on line blocks that move text are carried out on the line immediately below the cursor. Operations on box or stream blocks that move text begin at the column of the cursor. If you mix block types, tde uses the last specified block type. @B - Mark Box Block This key is used to mark both the beginning and ending corner of a box block. Press @B to mark the beginning line/column. Then, move the cursor to the ending line/column and press @B again to define the block. You can move the cursor around and press @B to adjust to size of the block as needed. @L - Mark Line Block This key is similar to the operation of the box block, but entire lines are marked. @X - Mark Stream Block All the text between the beginning and ending column, sorta like a stream of characters, is marked. @U - Unmark Block If you make a booboo when marking blocks, press @U to unmark the block and start over. After certain block operations, the block may remain marked - just press @U to unmark it. @G - Group Delete block Sorta self explanatory. This function deletes the text in the marked block and unmarks the block. @M - Move block Move the cursor to the desired location and press @M to move the marked block. In line mode, the text in the original block is deleted and then inserted at the line immediately below the cursor. In box mode and stream, the original block is inserted into the text beginning at the column of the cursor and then the marked box block is deleted. After block moves, tde unmarks the block. Moving blocks within themselves is not allowed. @C - Copy block With line blocks, the block is copied to the line below the cursor. With box and stream blocks, the block is copied beginning at the column of the cursor - everything to the right of the cursor is moved right to make room for the block. Blocks may be copied within or between files. tde unmarks the block after the copy is complete. If you try to copy a Line block within itself, the block copy starts at the first line immediately after the marked block. @K - Kopy block Same as copy block except block stays marked. Sorta like a poor man's cut-and-paste buffer. @O - Overlay block You can only overlay Box blocks. Move the cursor to the location to begin the overlay and press @O. The original block stays marked after the operation. @F - Fill box block Fills the marked Box block with character. tde prompts you for the fill character. Press Escape key to abort the command. This function is useful for filling in a column of periods for tables and such. @N - Number box block tde prompts you for the starting number, the increment, and whether to left or right justify the numbers. tde only handles integers - no floating point numbers are allowed. I felt that there were too many things involved in real numbers, eg. number of significant places to left of decimal, to right of decimal, exponents, engineering form, scientific form, etc.... If you want real numbers, just use a combination of the number box and fill box functions. Use the fill box function to make a column of decimals and the number box function to fill in the left and right side of the decimal. @P - Print block Prints the block to the PRN device. I haven't tried redirecting the PRN, but it should work. This function prompts for block or file printing. Press ESC to abort. Once the printing starts, press ESC to stop. The block remains marked after the block is printed. @W - Write block to file Writes the marked block to a file. tde prompts for the file name. If the file exists, it deletes all contents of the existing file and replaces it with the marked block. Press ESC to abort. Once the writing starts, there is no safe way to stop it. The block remains marked after the block is written to a file. @E - Block expand tabs Expands the tabs in the marked block, which must be a Line block, using the current tab setting. The default tab setting is 8. You can change the tab setting at any time by pressing @T. The block remains marked after the block is expanded. @T - Block trim trailing Trims trailing space, if any, at the end of each line in a LINE block. The block remains marked after the block is expanded. @< - Block upper case Convert all lower case characters in the block to upper case characters. @> - Block lower case Convert all upper case characters in the block to lower case characters. @? - Block strip high bit Strip the high bit off all characters in the block. This function is useful when editing files produced by WordStar. Word Processing Commands: A few simple word processing functions are availale: word wrap, format paragraph, format text, left justify a line, right justify a line, and center a line. @V - toggle word wrap Turn word wrap on or off. Typing past the right margin automatically moves the word to the next line. If the cursor is somewhere in the line, words are pushed to the next line. This not really an autoformat function, but it's fairly close. In tde, other than margins, word wrap and format paragraph or format text have nothing to do with each other. Word wrap is used to push characters or the cursor to the next line when the right margin is violated. Format paragraph and format text can be used at any time - they do not depend on the state of the WordWrap flag. ^F6 - Set Left margin May be set to any column equal to or greater than 1 and less than the right margin. ^F7 - Set Right margin May be set to any column greater than the left margin and less than the maximum line length or 256. ^F8 - Set Paragraph margin The paragraph margin may be set to any column less than the right margin. @F7 - format paragraph Text is formatted from the beginning of the paragraph according to the current left, right, and paragraph margins. If the cursor is not on the beginning line of a paragraph, tde searches for start of the paragraph and formatting starts there. The entire paragraph is formatted according to the margins. ^B - Format Text Text is formatted from the cursor onward. This function does not search for the beginning of the paragraph to start the format. In some situations, I want the text above the cursor to stay like it is. It is useful 'cause it don't mess up special paragraph indentation. @F8 - Left justify Beginning of current line is adjusted to start at left margin @F9 - Right justify End of current line is adjusted so it ends at the right margin @F10 - Center justify Current line is centered between the left and right margins. Other keys: Enter Insert a newline at the cursor. If the cursor is in the middle of a line, the line is split at the cursor. The cursor moves to the next line. Indentation is matched if the editor is in the Indent mode. #Enter Move the cursor down a line. The cursor is placed on the first non-blank character in the next line. No lines are added to the file. ^Enter Move the cursor down a line. The cursor is placed on column 1 in the next line. No lines are added to the file. Up (arrow) Move cursor up a line if this is not the first line in a file and do appropriate vertical scrolling. Down (arrow) Move cursor down a line if this is not the last line in a file and do appropriate vertical scrolling. Left (arrow) Move cursor left one column if this is not column 0 and do appropriate horizontal scrolling. Right (arrow) Move cursor right one column up to column 255 and do appropriate horizontal scrolling. Home Move cursor to first non-blank character in the current line else move to column zero. Scroll to left as needed. Press Home to toggle between the first non-blank character and column zero. End Move cursor to 1st column past the last character in the current line else move to column zero. Scroll to right as needed. Page Up Move cursor up one page if this is not first page in file. Page Down Move cursor down one page if this is not last page in file. ^Right Move cursor one word right. ^Left Move cursor one word left. ^#Right (Control+Shift+Right) Pan the screen one character to the right. ^#Left (Control+Shift+Left) Pan the screen one character to the left. ^Home Move cursor to first line on screen. ^End Move cursor to last line on screen. If end of file occurs before last line of file, move cursor to last line in file. ^Page Up Move cursor to first page in file. ^Page Down Move cursor to last page in file. Zip to line Move to line number. tde prompts for line number. Press Escape to abort. Center The cursor is moved to the center of the current window. ^Center The line the cursor is on is moved to the center of the current window. ^Up Scroll window up 1 line with cursor staying on same line in file. ^Down Scroll window down 1 line with cursor staying on same line in file. Grey - on key pad Scroll window up 1 line with cursor staying on same line in file. Grey + on key pad Scroll window down 1 line with cursor staying on same line in file. @Grey Up (the arrow in the cursor/control cluster) or ^Grey - (grey - on keypad) Fixed scroll window up 1 line with cursor staying on same line on the screen as the file scrolls up. @Grey Down (the arrow in the cursor/control cluster) or ^Grey + (grey + on keypad) Fixed scroll window down 1 line with cursor staying on same line on the screen as the file scrolls down. @Grey PgUp Horizontal page left. @Grey PgDn Horizontal page right. ESC - undo line Get back the original unchanged line. When cursor is moved off a line, all changes to the file are made and there is no way to get back the contents of a line. Del Delete the character, if any, under the cursor. ^Del Toggle the delete stream mode. In stream mode, pressing the Del key will delete the characters in the file as if they were a stream. Lines will be joined at the cursor and eventually every character in the file may be deleted. In line mode, only the characters on a line may be deleted. Backspace Delete the character to the left of the cursor and move left. If the cursor is on the first column of a line, the current line is joined with the line above. If in indent mode and the cursor is on the first non-blank character, tde matches the indentation of the previous line(s). Tab If in insert mode, insert the appropriate number of spaces for a tab and move the cursor left. If in overwrite mode, just move the cursor left w/o inserting text. Ins Toggle between insert and overwrite mode. In insert mode, the cursor is normal size and an "i" is displayed at bottom right of screen. In overwrite mode, the cursor is 3-4 times normal size and an "o" is displayed at bottom right of screen. @I Toggle between indent and no indent mode. In indent mode, tde searches for the first non-blank character on previous lines and places the cursor on that column when a carriage return is pressed. When backspacing in indent mode, tde lines up the indentation with the first non-blank character of the previous line(s). @R - Toggle ruler Toggle display of ruler in all visible windows. @= Duplicates the current line. Duplicating the last (NULL) line in a file is not allowed. The cursor stays on the current line and the duplicated line is inserted after the current line. @- Deletes the text from the cursor to the end of line. ^Y Deletes current line, cursor does not move. @D Deletes current line, cursor does not move (exactly same as ^Y). @Y or ^U Undelete the most recently deleted line. The undelete buffer has room for 20 lines. If more than 20 lines are deleted, the oldest line is pushed out and the new one is added. You may press @Y repeatedly to undelete all the lines in the buffer. Deleted lines from line delete, delete to end of line, word delete, join line, and backspace are stored in the undelete buffer. @A Add a blank line below cursor. @S Split line at column of cursor. If in indent mode, the split line is autoindented. @J Join the current line with the line below. The text from the cursor to the end of the current line is deleted and the first character of the line below becomes the new character under the cursor. @T Set tabs. tde prompts for new tab setting. The default is 8. ^] Paren Balance. This function is really nice for C programmers because it balances parenthesis, brackets, and braces. If the character under the cursor is a paren, bracket, or brace, tde searches either forward or backward through the file for the balancing opposite. The cursor is moved to the balancing opposite if found. @Z Toggle writing control Z at the end of file. The default is leave the control z out. @1 - @3 Set a file marker. There is not a total of 3 markers for your use. Each file may have up to 3 markers. #@1 - #@3 (Shift+Alt+1 thru Shift+Alt+3) Goto a previously defined file marker. Toggles: ^F1 Toggle cursor sync. Only cursor movement commands are synced. Commands that change text are not synced. This feature is really handy when comparing different files. You will also notice that this feature is a lot easier to use when you use a hilited cursor line because you can see what the cursor is doing in other windows. ^F2 Toggle eol display. A special character is diplayed in the column of the actual new line. ^F3 Toggle writing <CR><LF> or <LF> at end of line. tde will read a text file with lines that end in either method; however, you may want to write the file in a different method. I think *nix systems only want a <LF> of the end of line. ^F4 Toggle trimming trailing space at the end of line. A 'T' is displayed in the bottom right of the mode line to indicate trailing space is trimmed. WordStar type commands: A limited number of WordStar type commands are implemented in tde. I have no plans whatsoever to implement any additional WordStar type commands. This implementation may not correspond exactly to the WordStar command convention.
