______________________________________________________________________________ Introduction LIST is a user supported program. It is not public domain. You may use LIST and give it to your friends, but you may not sell it or use it in business without obtaining a license. See the last page for information about licensing. You use LIST to display files on your monitor, line by line with the aid of scrolling, positioning and filtering commands. LIST PLUS has many new commands which go beyond usual file viewing and browsing. We will explain how LIST is used, and then how the new file management commands are used. Before going into all of the ways in which LIST can be used to display files, let's look at the three different varieties of LIST so that you understand the capabilities of each. Then, we'll go on and define certain terms like: redirection, piping, and filtering. In this way, you will better understand how you can use these things with LIST. Page 1 LIST User's Guide Getting Started ______________________________________________________________________________ Introduction Installation There are three varieties of the LIST program on the disk that you received (or in the file that you downloaded). This allows you to pick the version of LIST that is right for you, and to configure it to be exactly the way YOU want it to be. Decide which of the LIST programs you would like to use and copy the .COM file to your working disk, or into a subdirectory on your hard disk. Selecting a directory that is in your PATH will allow you to use LIST from anywhere on your system. You may rename the program file to any convenient name, such as L.COM, READ.COM, LST.COM or leave it as LIST.COM. For example, place the distribution disk into drive A and enter the commands: A: COPY LIST.COM C:\L.COM to copy the Plus version to the root directory of your C drive, renaming the program to L.COM in the process. Printing the manual To print the documentation, set your printer for six lines per inch, and 10 characters per inch. Then, use the DOS PRINT command. For example, PRINT LIST.DOC You may also print out the documentation by using redirection and entering: TYPE LIST.DOC > LPT1 Better yet, use LIST to print the manual. Enter LIST LIST.DOC then press the Ctrl and P keys at the same time. LIST User's Guide Page 2 Getting Started ______________________________________________________________________________ Varieties of LIST.COM - LISTS.COM small version - runs in about 30k - limited to smaller files (around 600kb), - excludes the Alt-X (screen saving) function - excludes the Alt-G (goto DOS) function - the Help screen is minimal. - LISTR.COM regular version - runs in about 80K - handles files up to 16 mb - excludes the Alt-V (file selection) function - excludes the Alt-I (insert filename) function - the Alt-W (windowing function) is minimal, i.e. you get two equal sized windows; there is no ability to change window dimensions - LIST.COM PLUS version - plus Alt-V file selection menu - plus file management functions like copy and delete - plus Alt-I hypertext-like file selection - plus a help screen for the file selection Alt-V functions - plus a second help screen for regular functions - plus the Ctrl-T telephone dialer Page 3 LIST User's Guide Getting Started ______________________________________________________________________________ Varieties of LIST.COM The documentation file is marked with | before new and changed lines. It is marked with a double asterisk ** for LIST PLUS only features. WARNING: LIST PLUS (LIST.COM), HAS THE ABILITY TO *DELETE* FILES FROM YOUR SYSTEM!! IF YOU ELECT TO USE LIST PLUS, PLEASE READ THE SECTION ON THE FILE SELECTION MENU FOUND LATER ON IN THIS MANUAL. LIST User's Guide Page 4 Definition of DOS terms ______________________________________________________________________________ DOS Redirection The output of a DOS command can be "redirected" to a device other than the standard output device, which is in most cases, the monitor. This is done simply by entering the command, followed by a ">" and then the name of the desired device. For example. If you type "DIR > FILE.LST" you will see nothing on your screen and then suddenly your DOS prompt will reappear. What happened? The "output" of the DIR command was "redirected" to the file, FILE.LST. In the same manner, you could enter the following command and send the contents of FILE.LST to your printer, like so: "TYPE FILE.LST > LPT1" The ">" symbol stands for redirection of output to another device. Broken down simply, the following command is saying: DIR > FILE.LST (send output of this) (TO) (This device, which is a file) By the same token, you can also redirect "input" to a DOS command or a program like SORT by using the "<" symbol. Here is an example: "SORT < FILE.LST" This command would take the information in FILE.LST and "redirect" it into SORT. For more information on redirection, you may want to consult a DOS manual or other such reference. Page 5 LIST User's Guide Definition of DOS terms ______________________________________________________________________________ DOS Filters FILTERS are commands, or programs, that read data from an input device, and then rearranges or "filters" the data before it then outputs the filtered information to an output device. DOS comes with several "filters", one of which is SORT. The following command would sort the file in alphabetical order. SORT < FILE.LST You are redirecting the file, FILE.LST through the SORT filter and it is rearranging the file. Taking what you know about redirection and filters, you could now send your alphabetical list to yet another file by entering: SORT < FILE.LIST > ALPHA.LST, which redirects FILE.LST into the SORT "filter" and then redirects the new output to the file ALPHA.LST. LIST also has some very helpful "filters" built right into it and we'll discuss these later on. Simply keep in mind that when you use a "filter" it will rearrange or alter the information into a form that is more presentable, or useful, to you. LIST User's Guide Page 6 Definition of DOS terms ______________________________________________________________________________ DOS Pipes Pipes are quite similar, in some ways, to redirection. They are "connections" between two programs or two commands or a command and a program. Pipes take data that is output from one program and redirect it as input to a second program. The DOS symbol for a pipe is the vertical bar "|". To redirect the output from one program or command to another, you simply type the first command followed by a vertical bar and then followed by the second command. Here is an example of piping. DIR | FIND "-88" This command tells DOS to send the output of the DIR command, which you would normally see on the screen, and send it through the FIND filter. FIND would be searching each line for the string "-88". Only the files in the current directory that have a 1988 date stamp would be displayed on the screen! You can use more than one "pipe" in a command. Take this final example: DIR | FIND "-88" | SORT/+14 > PRN A "pipe" takes the output of the DIR command and converts it into input for the FIND filter. Then, a second "pipe" is used to send the output from FIND as input to the SORT filter. As a last step, output from SORT is redirected to the printer! What would this command do?? It would take the DIR of the current directory and pipe it through the FIND filter, looking for files created in 1988. Then the next pipe would SORT that information, sorting the files by SIZE (the 14th column of each line) and then send the output to the printer. For more information on PIPES, consult a DOS manual or other reference. Now that you have a basic understanding of redirection, filtering, and piping, we will go on to discuss the command line of LIST. Page 7 LIST User's Guide Command line ______________________________________________________________________________ Command line syntax The command line format is: LIST [filespec...filespec] [/switches] You may supply one or more file specifications (filespecs). LIST will display each file which has a filename matching one of the filespecs. If you do not supply one, LIST will prompt you for a filespec, or present you with a file selection menu. Command line switches /? displays LIST usage information /B tells LIST to use the BIOS for displaying data instead of using direct screen writes /D forces display of the File Selection menu for the specified files, e.g. *.TXT for a menu display of only files with an extension of TXT /E tells LIST to begin displaying the files from the end of each file instead of from the beginning /K disables the mouse; both /M and /K mouse options are clonable /Q toggles sounding of beeps; the same as Alt-Q /V causes a verify operation to be performed after any Copy or Move operation; the /V option defaults to the value of the DOS VERIFY setting /4 places LIST into 443 (or 50) line display mode; this requires an EGA or BGA display adaptor /S indicates viewing a piped or redirected file /J sets Junk filter on /7 sets 7-bit display /8 sets 8-bit display /* sets star filter on LIST User's Guide Page 8 Command line ______________________________________________________________________________ /W sets Wrap on /H sets Hex dump mode /L sets pre-Loading on /M allows use of a mouse for moving the cursor /K disables mouse for cursor positioning /Ftext begins a text search through all of the selected files and is case insensitive /Ttext searches all files immediately for the 'text' and is case sensitive; the /Ftext and /Ttext options MUST be the last options on the command line; both cannot be used at one time /#nnnn begins displaying the file at record 'nnnnnn' The command line switch character is normally a slash, "/", but LIST will use whatever character that is defined to DOS as the command line switch character, e.g. a dash, "-". Depending on your needs, you could load LIST using any of these command line switches, such as: LIST MYFILE.TXT /W which would set Word Wrap ON. LIST MYFILE.TXT /J which turns on the JUNK filter The L, W, M, S and /J command line switches may be used to disable the corresponding option by adding a minus symbol to them. For example, /-W or /W- will set wrap off. The B, D and Q switches are toggles. That is, specifying them reverses the default, or cloned, setting. Page 9 LIST User's Guide How to use LIST ______________________________________________________________________________ Starting LIST To start LIST, you type the command LIST, at the DOS prompt, followed by the name(s) of the files that you want to see. For example: C:>LIST CONFIG.SYS (displays file CONFIG.SYS) C:>LIST *.DOC (displays all DOC files in current directory) The "filename" is optional. If omitted, LIST PLUS will bring up a display of ALL files and subdirectories in the current directory. You may use the cursor keys to highlight the file that you would like to work on and press ENTER. Or, you may highlight any sub- directory entry and press ENTER to change to that subdirectory. You may also use LIST to display piped or redirected files. A discussion of redirection, piping, and filtering is at the beginning of this manual. To display a redirected file, use a < (less than symbol) before the name of the file that was redirected and add the /S parameter to the LIST command. For example, the output of the DIR command can be written to a file called XYZ, and then LIST can be instructed to read that file. dir a: >xyz list <xyz /s To see a piped file, omit the filename, but supply the /S. dir a: | list /s Or, to LIST a file within an ARC archive: ARC /p arcname.arc filename.ext | list /s - or - ARCE arcname filename.ext /p | list /S Here, the ARC or ARCE program is invoked to extract the 'filename.ext' file. The /P switch for these programs sends the output to the standard output device, and this output is piped to LIST. Once the file is displayed on your screen, you may use the cursor positioning keys to move around and see different parts of the file. There are also commands to search for text, print, split the screen, display other files, change colors, change the way the data is displayed, and many other operations. LIST User's Guide Page 10 How to use LIST ______________________________________________________________________________ Exiting LIST There are several ways to exit LIST depending on how you want the screen to look. The F10 command returns you to DOS with the DOS prompt on the bottom line. The last page that was displayed by LIST is left on the screen. The ESCape key also returns you to DOS without changing the screen. In LIST PLUS, the ESCape key is also used to cancel an operation, or to exit file selection menu. The X command returns you to DOS and clears the screen. The DOS prompt is on the top line of the screen. The Alt-X command uses the screen saving feature. It returns you to DOS and displays the screen that you had before LIST was run. Entering Commands You enter commands by pressing a single key, or a combination of keys. There are often several ways to perform the same function with different keys. For example, D and PgDn both perform a scroll down one page function. This lets you pick the keys that you are most accustomed to. When you press keys, they are entered into a keyboard buffer. Holding down a key can put many copies of that key into the buffer. This means that when you let up on a key, the program can still be processing input from the keyboard buffer. For example, by holding down the PgDn key, LIST scrolls down one page for each time the PgDn key is placed in the keyboard buffer. When you let up on the key, the buffer may not yet be empty and LIST will continue to page down. To make LIST stop when you let up on a key, you use the Alt-K key-ahead toggle. Keyboard enhancement utilities, such as PCED, may also change the way that LIST reads the keyboard. With PCED, for example, pressing the ESCape key at a prompt is different. You do not see the / that DOS normally sends when you cancel an input line. Page 11 LIST User's Guide How to use LIST ______________________________________________________________________________ Display Format The monitor display is defined in terms of lines and columns. A typical monitor can display 25 lines of 80 columns each. LIST attempts to use the number of lines and columns for the monitor mode in use. For example, if the monitor is in 132 column mode, LIST displays 132 characters per line. If the monitor is set for other than 25 lines, such as 35, 43, or 50 lines, LIST displays that many lines per screen. If you use the Alt-E command to change EGA/VGA modes, the EGA palette, cursor, and other settings are set to the DOS default values. LIST does not preserve fonts or palettes. The top line of the display is called the Status line. The bottom line is called the Command line. The remaining lines are called the primary display window, and are usually lines two through 24. Status Line Format The Status line has two formats. The default format is: ┌──────────────────────────────────────────────────────────────────────┐ │ LIST lllll nnnnnnn +sss mm/dd/yy hh:mm - filename │ └──────────────────────────────────────────────────────────────────────┘ where, 'LIST' is the name of this program 'lllllll' is the line number of the first line in the primary display window (under the status line) 'nnnnnnn' is the line number of the last record of the file; if the last record of the file has not been read, this field shows the percentage of the file that has been read '+sss' if displayed, this is the Scroll amount, in multiples of 10, corresponding to the number of columns that the display has been shifted to the right to view records longer than 80 'mm/dd/yy' is the file's creation date (not today's date); or 'dd-mm-yy' is the file's date in European format 'hh:mm' is the file's creation time (not today's time) 'filename' is the name of the file you are currently viewing LIST User's Guide Page 12 How to use LIST ______________________________________________________________________________ Display Format Note: The date and time shown on the top line is NOT the current date. It is the date and time that the file was created. Page 13 LIST User's Guide How to use LIST ______________________________________________________________________________ Display Format Use the Alt-Z command to change the Command Line to this format: ┌──────────────────────────────────────────────────────────────────────┐ │ LIST 70 2153 +20 09-02-89 18:12 LIST.DOC │ └──────────────────────────────────────────────────────────────────────┘ By using the Alt-R ruler toggle, the top status line becomes: ┬┬┬┬┼┬┬┬10┬┬┬┬┼┬┬┬20┬┬┬┬┼┬┬┬30┬┬┬┬┼┬┬┬40┬┬┬┬┼┬┬┬50┬┬┬┬┼┬┬┬60┬┬┬┬┼┬┬┬70┬┬ or, in Hex Dump (Alt-H) display mode: Offset: 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F ----- DATA ----- LIST User's Guide Page 14 How to use LIST ______________________________________________________________________________ Command Line Format The Command line has two formats. The default format is: ┌──────────────────────────────────────────────────────────────────────┐ │ Command Keys: ^v-><- PgUp PgDn F10=exit F1=Help │ └──────────────────────────────────────────────────────────────────────┘ and the optional format after using the Alt-Z toggle is: ┌──────────────────────────────────────────────────────────────────────┐ │ Command Toggles: h8kMpswTclJ F10=exit F1=Help │ └──────────────────────────────────────────────────────────────────────┘ where, 'command' indicates the current process: 'Command ' function prompt; you are being asked to enter a command; enter the letter, or press the keys for the action to be performed 'Reading ' the file data is being read 'Filter ' the file data is being formatted for display 'Looking ' the Scan/Find text is being searched for 'Scan ' you are being asked to enter text to locate 'Find ' in the file, up to 31 characters may be entered '# lines?' you are being asked to enter a 1 to 5 digit number that is the amount of lines to skip 'Line #?

'H' indicates that the hex Dump display option is in use 'b' the 'b' is replaced by a 7, 8, or * depending on which of those options is in effect 'K' indicates that the Keyboard flush option is in use 'M' indicates that tests for monitor retrace are not made 'P' indicates that Print is in use 'S' indicates file sharing option is in use 'W' indicates that the Wrap mode is in effect 'T' indicates that TAB characters are expanded 'C' toggles continuous scrolling 'L' indicates that the pre-loading option is on 'J' indicates that line feeds are added to lone carriage return control characters, and backspaces are handled A sample Command Line might look like this, after looking for a word that was not found: ┌──────────────────────────────────────────────────────────────────────┐ │ Command *** Text not found *** Toggles: h*kMpswTclJ F10=exit F1=Help│ └──────────────────────────────────────────────────────────────────────┘ LIST User's Guide Page 16 How to use LIST ______________________________________________________________________________ Scrolling You view different parts of the file by scrolling. That is, you use the cursor positioning keys up, down, left and right to move the display one increment in that direction. For example, press the down arrow key to move the display one line in the file, i.e. display the next line in the file. The PgDn and PgUp cursor keys move the display one full screen in either direction. Rather than press the up and down keys once for each line, you may use continuous scrolling. Use the C key to toggle continuous scrolling on or off. The default is off. When toggled on, pressing the up or down arrow keys results in a moving display. For example, when you press the down arrow, the next line of the file is displayed automatically every second, or so. It is like holding down the arrow key. To stop the continuous scroll, press the space bar. The speed of the continuous scroll can be adjusted by pressing the + (plus) or - (minus) key while the display is moving. The plus key makes the display move faster, and the minus key makes it move slower. You can save the speed value by using the cloning command (see Configuring LIST, Cloning, later on in this documentation. The speed is independent of the computer speed and can be adjusted from approximately 50 lines per minute to 1000 lines per minute. Page 17 LIST User's Guide How to use LIST ______________________________________________________________________________ Scrolling Summary of scrolling commands: right arrow - move display right 10 columns left arrow - move display left 10 columns down arrow - display next line of file up arrow - display previous line of file PgUp key - display previous "page", 23 (or 41) lines back PgDn key - display next "page", 23 (or 41) lines ahead C key - turns continuous scrolling on or off spacebar - or any key, interrupts continuous scrolling + (plus) - makes continuous scroll incrementally faster - (minus) - makes continuous scroll slower LIST User's Guide Page 18 How to use LIST ______________________________________________________________________________ Positioning to Lines Each displayable line of the file is assigned a line number. The first line is assigned line number 1. The highest allowable line number is 16 million. In order to determine the last line number of a file, the entire file must be read. For this reason, the first time that the END (bottom) command is issued, it will take longer to process. This is not necessary if the file has been completely read (see the Alt-L preloading option). If the Wrap option is in effect, there is one line number required for each 80 bytes of the file's records. Thus, the line number does not represent the actual number of lines in the file. If the hex dump option is in effect, there is one line number required for each 16 bytes of the file. For example, an 80-byte line will be displayed as 5 lines. You may position to a specific line number by using the Ctrl-Home, or the # key. When Ctrl-Home is entered, you are prompted for the line number. Enter the line number. The display will now begin with that line number at the top of the screen. To position forward or backward, you may use the + (plus), or - (minus) keys. You are prompted to enter the number of lines to be skipped. The display resumes at the line number shown on the top (status) line, plus or minus the number of lines that you specified. When you change a filter option, such as Wrap, the line numbering changes. An attempt is made to retain the same file position, but the file may be repositioned at the top. You may also reposition to the last "active" line by using the Alt-Y bookmark command. The last active line is one displayed after a Scan or Find command, or marked using the Alt-M or Alt-B commands, or the line set by the Ctrl-Y bookmark command. Up to ten book mark lines may be saved by Ctrl-Y and recalled by Alt-Y Page 19 LIST User's Guide How to use LIST ______________________________________________________________________________ Positioning to Lines Summary of positioning commands: Ctrl-HOME, or # - Prompts for exact line number to display + (plus) - Prompts for the number of lines to skip for positioning further ahead in the file - (minus) - Prompts for the number of lines to skip for positioning to an earlier line Alt-Y - Reposition to the last bookmark Ctrl-Y - Set new bookmark line number LIST User's Guide Page 20 How to use LIST ______________________________________________________________________________ Filtering Filtering is the term used to describe the process that LIST uses to format file data for displaying on a monitor. After data is read from a file, it is filtered. The method of filtering depends upon the options in effect. LIST is fastest with no filter options set. For a typical ASCII text file, the filter removes carriage return and line feed characters, and expands TAB characters. Because files contain different kinds of data, there are several commands to tell LIST how to display the data. The process that LIST uses to make the file data readable is called filtering. The filters in LIST can: o replace non-text and control characters with blanks o expand TAB characters o display line drawing characters o change 8-bit (W*) data to readable 7-bit text ** o display the hexadecimal values for each character o remove "junk", such as control codes and backspaces ** W* is an abbreviation for WordStar (tm) formatted files which contain 'high-bit' characters. Using the '*' filter makes these files easier to read. LIST was designed primarily to display ASCII files; that is, files which contain text, and not binary or control codes. Text characters, like A-Z and 0-9, are in the 7-bit range. Binary files like .COM and .EXE files, contain the full range of 8-bit characters and the Alt-H (hex dump display) command is available for viewing them. Characters above 127 (the 8-bit range) may be valid graphic characters, and may be displayed if the '8' command is in effect. To insure that characters above ASCII value 127 are NOT displayed, use the '7' command to limit the display to characters in the 7-bit range. Page 21 LIST User's Guide How to use LIST ______________________________________________________________________________ Filtering Wrap Filter The file is displayed with one logical record on each display line: usually 80 characters. A logical record ends in a linefeed and may be up to 2048 characters long. If a record exceeds 80 characters, you may view the portion beyond the 80 columns by using the scroll right command, or by using the Wrap feature. The Wrap (W) command toggles ON or OFF the wrapping of lines longer than 80 characters. With Wrap on, lines are displayed in their entirety, 80 characters per display line. The scroll left (arrow) and right (arrow) functions are disabled when Wrap is ON. Hi-bit Filter The 7, 8, and * (asterisk) commands determine whether characters above ASCII-127 are displayed. If the hi-bit option is off (7 command), the filter strips the high order bit from each character. If the hi-bit option is on (8 command), all characters, including graphic characters above ASCII-127, are displayed. Star Filter The star (* or asterisk) command displays only ASCII characters below 128 (x'80'), but treats the special characters x'8A' and x'8D' as line-feed and carriage-return control characters. Any other characters above 127 are treated as spaces, and control codes below ASCII-26 are replaced by blanks. Junk Filter The Alt-J command toggles the "junk" filter which insures that carriage returns in the file also result in a new line. Also, backspace characters result in "backing up" the display by one position. This allows more readability of files that use backspacing to emphasize, or over-write, characters. LIST User's Guide Page 22 How to use LIST ______________________________________________________________________________ Filtering Hex Format Filter The hex dump option (Alt-H) causes the filtering to reformat the file data into a DEBUG-like display format. The largest file that can be displayed in Hex is 4 million bytes. An attempt is made to retain the file position when switching from normal to hex-dump display, but due to filtering changing record lengths, the hex display may begin before the current record. Tab expansion filter The tab expansion option (Alt-T) cause LIST to insert spaces into a a line. The default tab expansion interval is eight spaces resulting in placing non-blank data in columns 1, 9, 17, 25, etc. The Ctrl-I command can be used to change the tab interval from 1 to 99. Summary of filtering commands: 8 show all characters as-is 7 strip the hi-bit from each character * use the star filter to remove control characters and some special word processor characters Alt-J use the "junk" filter Alt-H use the "hex" filter to display in hex dump format Alt-T expand TAB control characters Alt-W wrap long lines to fit on screen Ctrl-I define TAB interval Page 23 LIST User's Guide How to use LIST ______________________________________________________________________________ Scanning for text There are three ways to initiate a search for text. First is the Find (\ or F) command. Use this command to search for text without regard to the case (upper or lower) of the letters. Second is the Scan (/ or S) command. Use this command to search an exact match. That is, the search is case-sensitive. The third way to initiate a search for text is with the /F command line switch. With it, you supply the text to search for, and LIST begins the search before displaying the file, and before asking for commands. The search continues through all selected files until a match is found, or the last file has been searched. This search is case-insensitive. Each search begins at the line displayed on the top of the screen and proceeds in a forward direction until the end of file. You may start a search that goes backwards rather than forwards by using the ` (left quote) key instead of Find (\), or by using ' (right quote) instead of Scan (/). To enter the Scan search text, type a slash (/) followed by up to 31 characters. The Scan text is displayed on the command line. The Scan is case-sensitive. That is, lower case Scan text will only match lower case file text. While the program is searching for the text, the bottom display line is changed to say "Looking". Pressing ANY key while the search is in progress will terminate the search and display the message 'Text not found' on the bottom line. If the text is found, the line containing it is displayed as a high-intensity line (bright color) in the middle of the screen. The search text is displayed in reverse video colors on the highlighted line. The line where the found text is displayed depends on the setting of the "Find Row" (see Configuration section). The display is scrolled left or right, as needed, so that the found text is visible. If the text is NOT found, the command line is changed to say '*** Text not found ***', and the rest of the display remains unchanged. To find the next occurrence of the same text, use the A)gain command, or press the F3 key. If you wish to continue the search through all of the remaining files, use the Alt-A command. To find the previous occurrence, press the F9 key. LIST User's Guide Page 24 How to use LIST ______________________________________________________________________________ Scanning for text If the a keyboard enhancement program, such as PCED, is installed, the up/down cursor keys may be used to recall and edit previously entered Scan/Find text. In a shared file environment, if the file changes while being listed, the file position may become invalid. Use the HOME command to insure proper file synchronization, or use the Alt-S (share files) command again. Summary of scanning commands: / or S Scan for text with exact match v or ' Scan for text going backwards \ or F Find text with case-insensitive search ^ or ` Find case-insensitive text going backwards F3 or A Find next occurrence of text F9 Find previous occurrence of text Alt-A Scan for next occurrence of the text, and continue on to the next file until the text is found Page 25 LIST User's Guide How to use LIST ______________________________________________________________________________ Marking and Extracting Lines There are two ways that lines can be extracted from a file: o with the P (print) and Alt-P (print marked) commands, o with the Alt-D (dump data) and Alt-O commands. The lines to be extracted are either the current lines on the screen, or lines that you have marked with the Alt-M and Alt-B commands, or a line found by the Find or Scan commands. To mark lines, you use either the Alt-M or Alt-B commands. The Alt-M command marks the top line on the screen, and Alt-B marks the bottom line on the screen. You can use either or both commands to mark the starting and ending lines (in the range of lines to be extracted). The marked lines are displayed in reverse video. After you have marked a range of lines, you use the Alt-P (print) command to print all of the marked lines. Or, you can use the Alt-D (dump data) command to write those lines to a file. The Alt-D command asks you for a file name. If the file does not exist, a new one is created. If the file already exists, the extracted lines are added (appended) to the file. If no lines are marked, Alt-D either writes the current line (top line) or the highlighted line that was found by the Find or Scan commands. For example, you would like to have LIST filter out all of the junk in a file, and then write a new file. To do this, you might enter the following sequence of commands: list TESTDATA ... display your TESTDATA file Alt-J ... filters out the junk Alt-M ... marks line 1 (top line) END ... positions to end of file Alt-B ... marks the bottom line (last line) Alt-D ... dumps data to a file TESTDATE.NEW ... you enter the new file name Alt-X ... quit and return to DOS Once you have marked a range of lines, use of Alt-M or Alt-B does not reset the entire line range. The first or last marked line may change, but both do not change. Using Alt-M again expands or LIST User's Guide Page 26 How to use LIST ______________________________________________________________________________ Marking and Extracting Lines contracts the range appropriately. If the new line for Alt-M/Alt-B is before the top mark, the top mark is moved. If the new line is after the bottom mark, the bottom mark is changed. If the new line is within the currently marked range, Alt-M moves the top mark - contracts the range - and Alt-B moves the bottom mark. If no lines are marked, but there is a "found" line on the screen as the result of a search by Scan or Find, Alt-D and Alt-O will write the found line to the file. Use the Alt-U command to unmark lines, especially after Alt-D (dump) to be sure. Page 27 LIST User's Guide How to use LIST ______________________________________________________________________________ Printing The file may be PRINTed as it is displayed, in its entirety, or from a range of lines that you mark. If the printer is not online, you will receive an error message, and nothing will be printed. The P command toggles the printer on or off. When first entered, the P command causes the current screen to be printed. As new lines are displayed, they too are printed. For example, pressing the down arrow will display and print the next line of the file. Printing may be stopped by entering another P command. The PrtSc key may also be used, but the title and prompt lines will be printed with the lines of the file. Empty lines cause a line to be skipped on the printer. The capital letter P is displayed on the status line while printing if the bottom line is set to show TOGGLES. The Ctrl-P command prints the file in its entirety. The Ctrl-F command sends a form feed to the printer. The printer defaults to the LPT1 or PRN device. The Alt-P command prints only lines that have been marked. LIST User's Guide Page 28 How to use LIST ______________________________________________________________________________ Displaying multiple files You can display more than one file at a time. LIST keeps track of up to 32 files at a time. You supply the filenames in the command line, through the Alt-F (get new filespec) command, through the Alt-I (insert filespec) command, and through the Alt-V file selection menu. The Alt-F command is disabled whe viewing a piped file. You can specify up to 16 filespecs on the command line. Each filespec can contain wildcards. Thus, several files can be selected via the command line. For example, LIST *.DOC *.TXT will display all files with an extension of DOC and TXT. To display the next file, you use the Q or Ctrl-PgDn command. When the last file has been displayed, you can exit LIST by using the X, F10, ESCape, or Alt-X commands, depending on how you want the screen to look when LIST ends. To display the previous file, you use the Z or Ctrl-PgUp (control and PgUp keys together). The 1 command restarts the displaying of files with the first file. LIST can keep track of up to 32 files at one time. The line number for each file is remembered. The Alt-F asks you for a new file name, and you may enter a simple file name, or one that includes wild cards. These new file names are added to the table of filenames that LIST keeps. Thus, you can use Alt-F for several different filenames, and use the Ctrl-PgDn and Ctrl-PgUp commands to move among them. The Alt-I command allows you to select a filespec that is in the file you are viewing. You position the cursor to the filespec on the screen, and press enter to add it to the list of files to display. The Alt-V command displays a list of file in the current directory. You move the cursor to a file that you want to display, and press enter to add that file to the list. Page 29 LIST User's Guide How to use LIST ______________________________________________________________________________ Displaying multiple files Summary of file review commands: Q - display next file, if any Z - display previous file 1 - display first selected file Ctrl-PgUp - display previous file Ctrl-PgDn - display next file 1 - restart displaying with first file Alt-F - prompt for new filename or filespec to display Alt-I - insert a filespec that is displayed Alt-V - select a file from a menu LIST User's Guide Page 30 How to use LIST ______________________________________________________________________________ Windows LIST can display data in one or two parts of the screen called windows. The Alt-W command toggles this split screen mode. Entering Alt-W while the screen is split restores the display to a single, full sized display. In the regular version, the screen is split in the middle. The top half of the screen remains the same, and the bottom half becomes the part of the screen where files are displayed. Thus, the top window becomes a scratch pad. In the LIST PLUS version, you are allowed to split the screen at any point. After entering Alt-W, you are asked to position the cursor to the spot where the screen will be split. By placing the cursor in column 1, you can adjust how many lines will be used by the top and bottom windows. This would be a vertical, or one window above the other, split. By positioning the cursor to the top line with the HOME key, you can then use the left and right arrow keys to adjust how wide each of the windows is to be. This would be a horizontal, or side-by-side split. You may display a different file in each window, and move between them. You use the Ctrl-V command to switch from one window to the other. You may also use the Review commands to display a different file in the second window. The Ctrl-V command has no effect unless you are viewing two or more files, i.e. a different file in each window. Each window uses different colors. You can use the color commands to set the colors that you like, and then use the Alt-C command to save them. Page 31 LIST User's Guide How to use LIST ______________________________________________________________________________ Telephone dialer LIST has a simple telephone dialer function. It allows you to point to a telephone number that is displayed on the screen, and to send dialing commands to your modem on COM1. You use the Ctrl-T command to start the dialer. You position the cursor, with the arrow keys, to the start of the phone number and press enter. The phone number may contain any character, but must end with a blank. If a highlighted line is displayed on the screen as a result of Find or Scan, the cursor is initially placed at the found text. If the phone rings, you may pick up your telephone. Otherwise, you may press <enter> to return to viewing the file, <spacebar> to dial the number again, or ESCape to hang up and stop dialing. The Ctrl-H command hangs up the telephone. If you are using a communications port other than COM1:, see the file DIALER.PAT for information on changing LIST to use COM2: or another COM port. LIST User's Guide Page 32 DOS considerations ______________________________________________________________________________ File Sharing LIST uses two techniques for allowing you to share files with other processes, such as programs running under multi-tasking systems, in other windows, or on networks. The first technique is called "file closing" and is enabled by the Alt-S commands. This forces LIST to close the viewed file unless it needs to read from the file. If enough memory is available, the entire file may be loaded once and thus leave the file free for exclusive access by other processes. The second technique is called "file sharing". It is a function of DOS and requires DOS version 3.0 or later. LIST opens the viewed files with a DENY NONE request. This allows other processes to read and write to the file if they do not request exclusive use of the file. If a file is not available to LIST because it is locked by another process, you will receive the error message "File not found" or "Access denied". There is no command to enable or disable this method of file sharing. It is implicit with the use of DOS version 3 and later. Invoking DOS Commands If the "goto DOS" option is enabled, you may invoke DOS commands by using the Alt-G command. LIST reserves about 60k of memory for its own use. This increases LIST's memory requirements to approximately 96k when using Alt-G. The remaining memory is available to the DOS commands. Alt-G clears the screen and invokes the DOS command processor. After you have finished entering DOS commands, use the DOS EXIT command to return to LIST. To disable the "goto DOS" function, you must use DEBUG to alter the option byte described in the section about cloning. With it disabled, LIST requires less memory, about 66K. Page 33 LIST User's Guide DOS considerations ______________________________________________________________________________ Screen Saving If the screen saving option is enabled, LIST saves the contents of the current display screen when it starts. You can restore the original screen by exiting LIST with the Alt-X command. Screen saving requires approximately 10k more memory. This is sufficient to save 60 lines of 80 characters (EGA 8x6 mode). See the section about Configuring LIST and cloning for information about enabling and disabling the screen saving feature. The Alt-N command toggles the screen saving feature. Its status is not displayed on the bottom Line. The small version is the only one which defaults to disabling screen saving. LIST User's Guide Page 34 File Selection Menu ______________________________________________________________________________ LIST PLUS Display LIST PLUS has several new functions that greatly enhance the things that you can do. If you load the file LIST.COM (LIST PLUS) with no file specification, you would see something like this: ┌──────────────────────────────────────────────────────────────────────┐ │ LIST - File Selection 1 of 40 Path: C:\*.* │ └──────────────────────────────────────────────────────────────────────┘ ^.. ░ ░ vWPW ░WPSMALL .DRS░ vMAIN ░ ░ vWORK ░ ░ CONVERT .EXE░WPWSTAR .HLP░ STANDARD.PRS░WP}WP{ .TV1░ WP .EXE░STORY .DOC░ WP .FIL░FINDER .LTR░ WP .MRS░ ░ ┌──────────────────────────────────────────────────────────────────────┐ │ List Copy Del Edit Move Path Ren Sort Viewarc 1-6 up F10=Exit │ └──────────────────────────────────────────────────────────────────────┘ Note that the Command Line contains the following choices: LIST, COPY, DEL, EDIT, MOVE, PATH, RENAME, VIEWARC, SORT, 1-6 up Each of these commands may be executed from within LIST PLUS and are described below. Page 35 LIST User's Guide File Selection Menu ______________________________________________________________________________ LIST PLUS Display Movement Keys Use the arrow keys to move the cursor to a filename. The filename at the cursor is highlighted. The other cursor and filename selection keys are: PgDn - displays the next page of files PgUp - displays the previous page of files HOME - positions to the first filename on the screen END - positions to the last filename on the screen Ctrl-HOME - positions to the first filename Ctrl-END - positions to the last filename F1 - displays a Help screen F10 - exits to DOS in new directory ESCape - exits to DOS in the original directory Q - returns to viewing the last file, or returns to the File Selection menu X - exits to DOS in the new directory, this is the directory in which LIST is currently operating Alt-C - save settings (clone LIST.COM) Alt-X - exits to DOS and displays the screen as it was before LIST was used Alt-Z or / - toggles bottom line display from a menu or F3 command line to a statistics line: To position quickly to a give filename, press the shift key and the first letter of the filename at the same time. For example, to move the cursor to the filename LIST.COM, press shift-L. ┌───────────────────────────────────────────────────────────────────────┐ │ Files: 59 Used: 2367312 Free 1616912 F3=Menu F1=Help F10=Exit │ └───────────────────────────────────────────────────────────────────────┘ LIST User's Guide Page 36 File Selection Menu ______________________________________________________________________________ LIST PLUS Display Changing Directories Any subdirectories contained in the current directory will have a down arrow next to them. If you highlight one of these and hit Enter you will go to that directory. If the directory that you are in is a subdirectory itself, there will be an up arrow .. and selecting this will take you up. Thus, you can easily move around your hard disk from within LIST! List file This invokes LIST just as you would from DOS. Simply highlight the file that you wish to view, enter a carriage return, and you will be in LIST looking at the selected file. When you are finished, you may escape back to the original screen, with all of its options. You may also open a window and then, using the Alt-V command, get another file directory and select another file to view. Using Alt-W, you can load more than two files. Copy file This function allows you to copy the selected file to a new subdirectory. Highlight the file you want to copy and press ENTER. You will be prompted for the new path to which you want to copy the selected file. Enter the path, press ENTER, and the file is copied to the directory you indicated. Delete file Allows you to delete any file in the current directory. Just highlight the file you want to delete and press D and ENTER. You will then be prompted to make sure that you want to delete this file. Enter Y if you do, and N if you do not. Edit file Invokes the EDIT program for the selected file. If you do not have an editor called EDIT, create a batch file called EDIT.BAT which calls your editor with the parameters that you like. For example, peii %1 /pc:\pe2.pro /q Page 37 LIST User's Guide File Selection Menu ______________________________________________________________________________ LIST PLUS Display Invoke file Executes the selected file if it has an extension of .BAT, .COM, or .EXE. LIST reserves about 80k of memory and leaves the rest for use by the executed program. The I command is not listed on the menu. To cancel the command, press enter at the "Options:" prompt. Otherwise, supply at least one space for the program options. Move file Move any file in the current directory to any other directory. Select the file that you want to move by highlighting it and hitting ENTER. You will then be prompted for a new path. Enter the path and the file is moved to it's new location. Path changing This function allows you to switch to ANY other directory on your system without having to exit LIST! Enter 'P' for Path, and type in the full path of the directory that you would like to change to, for example: C:\DNLD. You will find yourself in the selected directory and still within LIST. The "\" character may also be used to change to another drive and/or directory. Rename Using this function you can rename any file in the current directory. Highlight the file that you want to rename. You will then be prompted for the new file name. After you have entered a new file name, you will be prompted to make sure that you really want to rename this file. If so, then respond with a 'Y'; if you've changed your mind, just answer with an 'N' and the renaming procedure will be abandoned. Sort filenames Allows you to sort the files in the current directory by file name, extension, date, or size. Once you have completed the operation you will find yourself back at the menu screen of LIST. The sort methods include F (by filename), E (by extension), D (by date), S (by size), and N (no sort). You may add a minus sign to the sort method to sort in descending, rather than ascending, order. LIST User's Guide Page 38 File Selection Menu ______________________________________________________________________________ LIST PLUS Display 1-9 up display This function lets you set the display to anywhere from 1 to 9 file names per line. In subdirectories with few numbers of files, you will begin to see not only file name, but file size, date, time, and attributes as well. You can customize this to suit your tastes. The 1-up display includes a display of the file attributes. These are: A - archive bit is on, the file is unchanged H - the file is hidden R - the file is marked read-only S - the file is a system file ViewArc This function will let you view the directory of an archive (.ARC, .ZIP, etc.) file, or self-extracting .COM and .EXE archive files. After you have viewed the desired file's directory, press ESCape to return to the file selection menu, or use the Alt-I (insert file) command to display a file within the archive file. The directory listing is written to a temporary file in the current directory and is called FVFVFVFV.FV$. You may tell LIST to place the temporary file elsewhere by setting an environment variable called LIST. For example, to place all ViewArc and Alt-I extracted temporary files on drive D in the subdirectory called TEMP, use the DOS SET command prior to invoking LIST: SET LIST=D:\TEMP To view archive directories, the program FV.COM is required. It must be located in a directory included in your DOS PATH. To display files within an ARChive file, the program ARCE.COM is required. It must be in your DOS PATH. For ZIP files, the program PKUNZIP must be in your PATH. Files with a .COM or .EXE extension are assumed to be self-extracting LHARC (.LZH) files.

The default is to display the cursor key usage. Using Alt-Z changes the bottom line to show the option switches "Toggles:" settings. Page 45 LIST User's Guide Configuring LIST ______________________________________________________________________________ Screen Colors The screen's lines may be in one of three different colors: o the 'special' color for the top status line and the bottom command line o the 'normal' color for the file's text windows o the 'bright' color for lines with Find/Scan text, and for the upside-down question mark in 7-bit mode There is a pair of function keys assigned to each color. You use these function keys at any time to change the background and foreground colors temporarily, or use the Alt-C cloning command to make the colors permanent. Alt-C requires that the LIST.COM program file be on the current drive and in the current directory unless you are using DOS version 3.3 or later. With DOS 3.3, the program file may have any name and may reside in any subdirectory. The border is not changed. The foreground color applies to the color of the characters. You may clone a second set of text colors for the second, and any other windows that you may create. The color attributes may be changed by using these function keys: For the main body of text: F5 - background color F6 - foreground color For the top and bottom lines: F7 - background color F8 - foreground color For the line with Find/Scan text: F2 - background color F4 - foreground Once you have decided upon the colors, use the Alt-C key combination to change the LIST.COM program file. This process is described below. LIST User's Guide Page 46 Configuring LIST ______________________________________________________________________________ Cloning The screen colors, the display retrace testing (M), the file sharing (S), ruler (Alt-R), and other options may be permanently set in the program COM file by using the Alt-C cloning function. For cloning to take effect, the program should be called LIST.COM and on the current drive and in the current directory. There are THREE versions of the LIST program file. One is the normal full program, which is LISTR.COM. The other, which is called LISTS.COM, is a slightly smaller file that excludes the Help screen. The third is LIST PLUS, found as LIST.COM. You may use any of the three COM files for cloning. After cloning, you may continue viewing the file. Several of the command toggles are also 'clonable'. The values and toggles that are cloned are: M = Mono monitor, affects retrace testing. If you see "snow" on your color monitor, turn off this option Alt-S = file(s) are shared W = Wrap long lines 8/7/* = display all 256 values, or 7-bit, or special case K = flush Keyboard each time a command is read Alt-H = hex dump display, like the DEBUG format Alt-J = toggle "junk" filter, add LF to CR, fix backspaces Alt-L = set on to force preloading (reading) of the entire file before any lines are displayed; default is OFF Alt-N = toggles screen saving (see Alt-X) feature Alt-R = toggle columnar ruler on top line Alt-T = toggle expansion of TAB characters (also Ctrl-I) Alt-V = number of filenames per line and sort method F2 = change background color for Find/Scan text F4 = change foreground color for Find/Scan text Page 47 LIST User's Guide Configuring LIST ______________________________________________________________________________ Cloning F5 = change background color for main body of display F6 = change foreground color for main body of display F7 = change background color for top and bottom lines F8 = change foreground color for top and bottom lines Note: Be sure you have no other copies of LIST.COM which are accessible (because of an APPEND type of utility). If you are familiar with the DOS utility DEBUG, you may want to modify LIST in that way. This is described in the next section. LIST User's Guide Page 48 Configuring LIST ______________________________________________________________________________ Modifying LIST.COM Locations of option values This information is offered to those of you who wish to modify LIST in special ways. You do not need this information to use LIST. An alternative to cloning is to use DEBUG to make permanent changes.

There are 128 regular characters and 131 extended characters. The regular characters are numbered from 0 to 127, and they include the letters A-Z, a-z, the numbers, and the rest of the usual single characters found on your keyboard. The extended characters represent special function keys and combinations of keys, such as F1, Alt-X, Ctrl-A, and the cursor positioning keys. The WHAT table in LIST has a one byte entry for each of the characters. This byte is a number from 0 to 57 that represents the identification of a routine that performs a function. For example, - the ESCape key has a value of 27 (hex 1B) and its value in the WHAT table is 16 (10 hex). Routine number 16 is called "Done". The "Done" routine exits to DOS. - the Q key has a value of 81 (51 hex) with a routine value of 15 for the "Close" routine. The "Close" routine ends viewing of the current file and tries to display the next file, i.e. wildcards used for the filename. There is also a lower case letter q, so be sure to change both entries. To change the function that a command character performs, you change the value in the WHAT table for the routine that the character invokes. For example, to change the ESCape key to act like the Q key, you change the routine value for ESCape from 16 (10 hex) to a 15 (0F hex). To find the location of the routine value in the WHAT table, first determine the value of the character, e.g. ESCape is 27 (1B hex), and then add that to the location of the WHAT table (36C hex); or, 1B + 36C = 387 hex. Finally, use DEBUG to change the byte at that location (387 hex) from a 10 hex to a 0F hex. For example, debug list.com ; use appropriate file name -e 387 0f ; change ESC to routine 15 -w ; old data is 10 -q LIST User's Guide Page 52 Configuring LIST ______________________________________________________________________________ Table of Routines Value Key(s) Description of function performed ----- --------- ------------------------------------------ 0 Error, undefined command 2 Alt-E Toggle EGA 43-line mode 3 Alt-F, G Get new filespec 4 Alt-J Toggle Junk filter 5 Alt-L Toggle pre-Load 6 Alt-T Toggle TABs expansion 7 Alt-W Toggle Split windows 8 Alt-X Exit to DOS, restore screen 9 U/up Position to previous line 10 END, B Position to end of file 11 F5 Change top/bottom line background color 12 F6 Change top/bottom line foreground color 13 Ctrl-HOME Position to specified line number 14 Alt-C Rewrite LIST.COM with new options 15 Q, Ctrl-PgDn Quit current file, display next file 16 ESC, F10 Exit to DOS 17 N, down Position to next line 18 X Exit to DOS, clear screen 19 Alt-H Toggle Hex display mode 20 8 Leave hi-bit 21 \, F Search for text, any case matches 22 F2 Change Find/Scan background color Page 53 LIST User's Guide Configuring LIST ______________________________________________________________________________ Table of Routines Value Key(s) Description of function performed ----- --------- ------------------------------------------ 23 F4 Change Find/Scan foreground color 24 Alt-M Toggle monitor rescan testing 25 K, Alt-K Toggle keyboard flush (type ahead) 26 Alt-G Invoke DOS command (shell) 27 L, left Scroll left 10 columns 28 - Position back by number of lines 29 enter Display next page 30 + Position forward by number of lines 31 P Print current screen or marked lines 32 F1 H ?
