TEXT EDITOR 2.5 USER'S GUIDE INTRODUCTION Text Editor (TE) 2.5 is a public domain, full screen ASCII text editor for the IBM PC and close compatibles which uses commands similar to those used in WordStar and Sidekick. Features include: o Display primary commands on pop-up help screen. Prompt for subcommands. o Insert, delete, split, join a line. o Copy, delete, move, read, write, shift, hide, display a marked block of partial or whole lines. o Print a file/block to LPT1-LPT3. o Enter any ASCII code. o Find/replace a phrase. o Temporary return to DOS. o Set left/right margins and page length. o Word wrap. o Format (justify) a paragraph. o Program size of 29,904 bytes. Primary uses for TE are to create/edit batch files, generate forms, edit files captured by telecommunications programs, write E-mail and simulate a "smart" typewriter. The file to be edited must be able to fit into available CPU memory. The ASCII file must consist of lines of characters that end with the CR character (ASCII 13). If the line contains more than 255 characters or doesn't end with a CR, the first 255 characters are retrieved and another line is started. EOF characters (ASCII 26) found before the true end of the file are ignored. INSTALLATION TE consists of one file TE.EXE with a size of 29,904 bytes. To load TE from any drive/directory, place TE.EXE in a directory that is listed in the DOS PATH statement. TE.EXE display colors, laptop display colors, cursor size, default margins, and default page length can be changed with utility program TEMOD.EXE. COMMAND SUMMARY The symbols c-, s-, a- mean press the Ctrl, Shift or Alt key simultaneously with the next key. Letters may be entered as upper or lower case. - 2 - +----------------------------------------------------------------+ | TEXT EDITOR 2.5 COMMAND SUMMARY | +-------------------------------+--------------------------------+ | TE [Path][FileName] | c- Ctrl s- Shft a- Alt | +-------------------------------+--------------------------------+ | File | +----------------------------------------------------------------+ | c-KD, c-KQ, F4 Save file and quit editor | | c-KE, F2 Save and/or load another file | +----------------------------------------------------------------+ | Cursor Movement | +-------------------------------+--------------------------------+ | c-S, Left Char left | c-QS, Home Line begin | | c-D, Rt Char right | c-QD, End Line end | | c-A, c-Left Prev word | c-QE, c-Home Screen top | | c-F, c-Rt Next word | c-QX, c-End Screen bottom | | c-E, Up Prev line | c-QR, c-PgUp File start | | c-X, Dn Next line | c-QC, c-PgDn File end | | c-W Scroll up | c-QB To block start | | c-Z Scroll down | c-QK To block end | | c-R, PgUp Up 23 lines | Tab Next word, prev line | | c-C, PgDn Dn 23 lines | s-Tab Prev word, prev line | | c-Q4 To specified line | c-Kn Set line mark n=0-3 | | c-QP Dn page len lines | c-Qn To line mark n=0-3 | +-------------------------------+--------------------------------+ | Insert/Delete | +-------------------------------+--------------------------------+ | c-V, Ins Insert/Replace | c-H, BkSp Delete left char | | Entr Split/Insert line | c-G, Del Del char/join line | | c-N, F9 Insert line | c-T Del next word | | c-Y, F10 Delete line | c-QY Del to end line | +-------------------------------+--------------------------------+ | Block | +-------------------------------+--------------------------------+ | c-KB, F7 Mark block start | c-KC Copy block | | c-KK, F8 Mark block end | c-KY Delete block | | c-KH Hide/display block | c-KV Move block | | c-KI Block right 1 char | c-KR Read block from disk | | c-KU Block left 1 char | c-KW Write block to disk | +-------------------------------+--------------------------------+ | Miscellaneous | +----------------------------------------------------------------+ | F1 Display summary of Text Editor commands | | c-QF Find phrase (1-31 chars) in file or block | | c-QA Find/replace phrase (1-31 chars) in file or block | | c-KP, F5 Print file or block to LPT1, LPT2, or LPT3 | | a-Xa-Ya-Z ASCII code XYZ = 32-255 on keypad | | c-P Then a-Xa-Y on keypad for ASCII XY = 1-31 | | c-KS, F3 Temporary return to DOS.

Where to find a pop-up screen of all TE commands. o Line and column position of the cursor. o Insert/Ovrwrite. If Insert mode, an entered character will be added at the cursor by moving the character at the cursor to the right. If Ovrwrite mode, an entered character will replace the character at the cursor. Press the Ins key to toggle between Insert and Ovrwrite. o The drive, directory, and name of the file currently being edited. o An asterisk "*" if character(s)/line(s) have been added or deleted. The status line and the next line are temporarily used for additional prompts required by some commands. STARTING TE TE is started by entering TE on the DOS command line. After TE is loaded, TE asks "File to edit:". If only the Enter key is pressed, TE will terminate and return to DOS. The drive/directory must be included if the file is not located in the current directory. The file name can be edited with the Home, End, Left/Right arrow, Del and Bksp keys as it is entered. If the file can't be found, TE asks "(file name) not found. New file (Y/N)?". Enter Y or N (upper or lower case). Pressing Enter after Y or N is not required. If Y, data may be entered into the new file. If N, TE asks "Enter another file name (Y/N)?". If Y, enter the file name. If N, TE will terminate. TE can also be started by entering TE and including the file name with optional drive/directory on the command line. For example: TE C:\DOC\234.DOC will load the TE program and file 234.DOC from drive/directory C:\DOC. FILE/QUIT COMMANDS Two primary file load, file save/no save , quit commands are available. Each command provides prompts for various options. c-KD or c-KQ or F4 Save File And Quit Editor ---------------------------------------------- c-KD means press the Ctrl and K (upper or lowercase) keys together. Then press D (upper or lowercase). If no changes have been made to the file, TE asks "File has NOT been modified. Quit editor (Y/N)?". If Y, TE will terminate and return to DOS. If N, TE can continue to be used with the current file. - 4 - TEXT EDITOR 2.5 USER'S GUIDE If changes have been made to the file, TE asks "Save file as: (file name) (Y/N)?". If N, TE asks "Quit editor (Y/N)?". If Y, TE will terminate. If N, TE can continue to be used with the current file. To save changes made to the file, TE asks "Save file with current file name (Y/N)?". If Y, the file will be saved with the current name and TE will terminate. If N, the current drive/directory and file name may be changed with the Home, End, Left/Right arrow, Del and Bksp keys. Press Enter to have TE save the new file name and terminate. Trailing spaces are stripped from the end of each line before the file is saved. If the message "Drive not ready or can't save file. Quit (Y/N)?" appears, it could mean the file is read-only. It is not possible to save changes to a read only file until the read-only attribute is removed by temporarily returning to DOS (F3 or c-KS command) and removing the read-only attribute with the DOS ATTRIB command. If a non-ASCII file (.COM, .EXE, .WK1, etc. ) or an ASCII file that contains more than 255 characters per line is loaded into TE, DON'T SAVE THE FILE!. TE will corrupt the saved file since TE loads all characters to the CR (ASCII 13) or the first 255 characters of each line and then starts another line. When the file is saved, trailing spaces (ASCII 20) are stripped and CR, LF (ASCII 13,10) characters are inserted. c-KE or F2 Save File And/Or Load Another File ----------------------------------------------- The c-KE (F2) command adds to c-KD (c-KQ, F4) the question "Continue editing same file (Y/N)?". If Y, the current file may continue to be edited. If N, TE asks "File to edit:". Enter a file name with optional drive/directory. If TE can't find the file, TE asks "(file name) not found. New file (Y/N)?". If Y, enter the new file name. If only the Enter key is pressed, TE will terminate and return to DOS. If N, TE asks "Enter another file name (Y/N)?". If Y, enter the file name. If N, TE will terminate. CURSOR MOVEMENT Tab and s-Tab ------------- Tab or s-Tab moves the cursor to a position which is equivalent to the next or previous word on the previous line. Tab and s-Tab commands do not insert tab characters (ASCII 9) into the file. If the file contains tab characters, they will be displayed as an "o" with the sides open. Tabs are not converted to spaces. Use the the c-QA Find/Replace command to convert a Tab character to 8 (typically) spaces. - 5 - TEXT EDITOR 2.5 USER'S GUIDE c-QP Down Page Length ----------------------- The cursor is moved down page length lines. The standard default value is 62 lines. It can be changed with the c-QM Set Left/Right Margins and Page Length command. This command is used to add headers, footers, page numbers, etc. at specified line intervals in the file. c-Qn To Line Mark n=0-3 ------------------------- Position cursor on the line previously set by c-Kn where n is marker 0, 1, 2, 3. The default line marks are 20%, 40%, 60% and 80% of the max lines in the file. If the file contains less than 5 lines, the default mark is line 1. c-Q4 To Specified Line ------------------------ Position the cursor at the line number entered when TE asks "To line:". The other cursor movement commands listed in the Command Summary section are self explanatory. INSERT/DELETE COMMANDS Insert/delete commands always operate on the line with the cursor. Ins or c-V Insert/Replace --------------------------- Toggle between character Insert and Ovrwrite (Replace) modes. Refer to the explanation in the Status Line section. Entr Split/Insert Line ------------------------ Split the line at the cursor position and move all characters over and to the right of the cursor to the next line. The cursor is positioned to the left margin of the next line. c-N or F9 Insert Line ----------------------- Move the line with the cursor down and insert a blank line. The cursor is moved to the left margin of the new line. If the current line is the last line in the file, a new blank line is added after the last line. c-Y or F10 Delete Line ------------------------ Delete the line containing the cursor. The cursor is moved to the left margin of the next line. BkSp or c-H Delete Left Character ----------------------------------- Delete the character to the left of the cursor. - 6 - TEXT EDITOR 2.5 USER'S GUIDE Del or c-G Delete Character/Join Line --------------------------------------- Delete the character over the cursor. If the cursor is beyond the end of the line, the next line is joined to the current line at the cursor position unless the current line is the last line in the file. c-T Delete Next Word --------------------- Delete all characters from the cursor position to the next space character. If the cursor position is at a space, all spaces will be deleted up to the next non-space character. If the cursor is beyond the end of the line, the next line is joined to the current line. c-QY Delete Characters To End Of Line --------------------------------------- Delete all characters from the current cursor position to the end of the line. If the cursor is at the beginning of the line, the line is made blank and not deleted. Word Wrap --------- Word wrap occurs when characters entered beyond the right margin or column 253 cause a word (all preceding characters up to the next blank character) to be moved to the next line. Word wrap is generated by the c-B Format Paragraph command (See Miscellaneous Commands section). The left/right margins are set with the c-QM command. The standard default left/right margins are columns 1/252 (See Miscellaneous Commands section). BLOCK COMMANDS Block commands mark, copy, move, delete, read, write, print, indent and unindent one or more partial/whole lines. c-KB or F7 Mark Block Start ----------------------------- Mark (high lite) the block start line and column at the current cursor position. The block will be default marked to the end of the current line. c-KK or F8 Mark Block Stop ---------------------------- Mark (high lite) all lines from the start block line and column, marked with c-KB or F7, to the line and column containing the current cursor position. c-KH Hide/Display Block ------------------------- Toggle between hide (remove high lite) or display (restore high lite) a marked block. If a block is hidden, the block can't be copied, moved, deleted, written, or printed. - 7 - TEXT EDITOR 2.5 USER'S GUIDE c-KC Copy Block ----------------- Copy the marked block to the current cursor position. The copied block is high lited. If part or all of a single line is marked, TE asks "Insert (Y) or Overwrite (N)?". If Y, the single line block will be added to the line by moving the characters at the cursor position to the right. If N, existing characters to the right of the cursor will be replaced. Multiple line blocks are always inserted at the cursor position. If a copy into a marked block is attempted, the operation will be canceled. If a combined line will contain more than 253 characters, the operation will be canceled. Use c-B Format Paragraph to justify text to left/right margins. c-KV Move Block ----------------- Move the marked block to the current cursor position. The moved block is high lighted. Otherwise the operation is the same as Copy Block. c-KY Delete Block ------------------- Delete the marked block. For multiple line blocks, the start line will be deleted if the start column is at the left margin. c-KR Read Block From Disk --------------------------- Read a specified file (block) from disk and insert at the line with the cursor. Text on the line with the cursor is moved after the inserted file. If the file is not found, the command will be canceled. The command remembers the last entered block read or block write file name. c-KW Write Block To Disk -------------------------- Write a marked block to disk. If the specified file already exists, it will be replaced with the contents of the marked block. If the disk (drive) is not ready, the command will be canceled. The command remembers the last entered block read or block write file name. c-KI and c-KU Move Block Right/Left One Character -------------------------------------------------- Move all lines of the marked block right (c-KI) or left (c-KU) one character position from the block start column. Characters will be lost if they are moved right, beyond column 253 or left, beyond column 1. The block end column is ignored. - 8 - TEXT EDITOR 2.5 USER'S GUIDE MISCELLANEOUS COMMANDS F1 Display Summary Of TE Commands ----------------------------------- The TE commands, remaining CPU memory and version number are listed. Press any key to return to the file being edited. This command can't be issued in the middle of another command. c-KP or F5 Print File Or Block To LPT1, LPT2, or LPT3 -------------------------------------------------------- TE asks "Print File (Y) or Block (N)?". If Y, the complete file will be printed. If N, the marked block will be printed. Next, TE asks "Printer LPT1, LPT2, LPT3 or Cancel (123C)?". Enter 1, 2, or 3 for printer number or C to cancel the print operation. If the printer is not ready (out of paper, off line, etc), TE asks "Continue (Y/N)?". Find the cause for the printer not ready, then answer Y. Otherwise, answer N to cancel the print operation. a-Xa-Ya-Z Enter ASCII Code 32-255 On Keypad ---------------------------------------------- ASCII codes, 32-255, that are not on the keyboard (i.e. line drawing characters) can be entered into the file by pressing the Alt key while simultaneously entering the 2 or 3 digit code on the keypad. The equivalent symbol will be displayed on the screen. c-Pa-Xa-Y Enter ASCII Code 1-31 On KeyPad -------------------------------------------- ASCII codes, 1-31, that can't be entered directly from the keyboard (form feed, Esc) can be entered by pressing c-P. Then press the Alt key simultaneously with a 2 digit code on the keypad. The equivalent symbol will be displayed on the screen. c-QF Find Phrase ------------------ When prompted with "Find:", enter a phrase of 1 to 31 characters. To prevent finding an embedded phrase, enter a space before and after the phrase. For example, enter <sp>the<sp> to prevent finding the word "other". Cancel the operation by pressing the Enter key only. TE asks for answers to the following options. o "File (Y) or Block (N)?". If Y, the search begins at the current cursor column, line. If N, the search begins at the start column, line of the marked block. o "Case sensitive (Y/N)?". If Y, the upper/lower case pattern of the letters in the phrase will be matched. If N, case sensitivity will be ignored. For example, the phrase "the" will find "The" and "the" if N. After each find, TE asks "Repeat (Y/N)?". If Y, the search continues until another find or the end of the file or marked block is reached. If N, the operation will be terminated. - 9 - TEXT EDITOR 2.5 USER'S GUIDE c-QA Find And Replace Phrase ------------------------------ The find/replace phrase command is similar to find phrase (c-QF) except a replace phrase of 1 to 31 characters must be entered in addition to "Find:" when prompted with "Replace:". Cancel the operation by pressing the Enter key only. In addition to the "File (Y) or Block (N)?" and "Case sensitive (Y/N)?" options, TE asks "Confirm replace (Y/N)?". If N, the replace phrase will be substituted for the find phrase until the end of the file or block is reached. If Y, the next two questions are asked each time the find phrase is found. o TE asks "Replace (Y/N)?". If Y, the replace phrase at the cursor will be substituted for the find phrase. If N, the find phrase will not be replaced. o TE asks "Repeat (Y/N)?". If Y, the search will continue. If N, the find and replace operation will be terminated. c-QS or F3 Temporary Return To DOS ------------------------------------ Return to DOS without removing TE from CPU memory (RAM). Run the DOS command or program that will fit in remaining memory. Type EXIT on the DOS command line to return to TE. Exercise caution when using this command. Other programs could corrupt RAM currently allocated to TE or crash the computer causing a loss of all data changes made to the file since it was last saved. c-QM Set Right/Left Margins and Page Length --------------------------------------------- TE prompts for answers to Left Margin, Right Margin, Page Length. The current values are displayed. The current values may be accepted by pressing Enter or the cursor keys may be used to edit/change the values. The standard defaults are: Left/right margin - Column 1/252, Page Length - 62 lines. c-B Format Paragraph ---------------------- A paragraph is formated with one space between each word, two spaces after each period and each line left justified to fit the maximum number of whole words between the current left/right margin columns until a blank line or end of file is reached. The command is ignored if the right margin is the default value 252. For example, the following paragraph will be processed as shown. Now is the time for everyone to come to the party. The time is now. Now is the time for everyone to come to the party. The time is now. The Format Paragraph command doesn't work correctly if a whole word is longer than the number of columns between the left and right margins. - 10 - TEXT EDITOR 2.5 USER'S GUIDE c-Kn Set Line Mark n=0-3 ------------------------- Set line mark n, where n is mark 0-3, to the line that currently contains the cursor. Use c-Qn to position the cursor to the specified mark n = 0-3. TE CHANGES FROM VERSION 2.2 TO 2.3 Blocks can be marked with start/stop columns as well as start/stop lines. The Block Right/Left Character commands (c-KI/c-KU) move all lines of the marked block one character position from the start block column instead of column 1. The following function key assignments have been added: F3 - Temporary return to DOS (c-KS), F5 - Print file or block (c-KP), F9 - Delete line (c-N). TE CHANGES FROM VERSION 2.3 TO 2.4 The Mark Block Stop command now works correctly if the stop location is before the Mark Block Start location. The Block Write command now remembers the last Block Write file name as well as the last Block Read file name. The status line cursor is placed at the beginning of the default/last entry instead of at the end. TE CHANGES FROM VERSION 2.4 TO 2.5 Added commands Delete Next Word (c-T) and To Specified Line (c-Q4).
