NZIP v2.02 (C)opyright 1990 Palmer Software by Andrew Palmer June 22, 1990 This is Version 2.02 of a Menu driven front end for PKZIP. It has gone through a major revision and now has more features and lets you get things done a little quicker. Packed into the .ZIP file you will find NZIP.EXE and NZIP.OLD. NZIP.EXE has been compressed with Fabrice Bel- lard's LZEXE. It runs fine. If for some reason you have to use the original (and 68K worth of) program it has been included as NZIP.OLD. I don't include the NZIP.OLD file in the CIS upload version since time is money on CIS. WHAT'S NEW IN 2.02: The <CTRL-F key> combos have been added. You can now manipulate up to five directory structures at a time via <CTRL-F4>..<CTRL-F5>. This requires more memory requirements so NZIP now reserves 200K for itself with whatever is left over for the archiver. The <ALT #> keys will also move through the active directory structures. The directory structure that is currently active will be used for file searches. Someone suggested to me the passing of environment variables (more specifically: why I didn't!) so I have added this in. If you specify the string '%ENV' in the 'Editor name' then NZIP will look for four environment strings which are used thus: NZOUT=path :specifies the output path for ZIP files and unzipping. EDIT=path/name :specifies the editor name to call. NZXL=path/name :specifies the name of the exclude file list. TEMP=path :specifies where to store temporary .ZIP file. Environment strings can also be used as input in certain cases when using NZIP and I will describe where this occurs. ALL environment variable input must be preceded by a '%' i.e., '%stdin' or '%temp'. If you use a number to run NZIP in command line mode i.e., NZIP 2 NEW NEW1 then environment the environment variables are automatically used. Another point is the 'Exclude files'. When NZIP begins running it will always look for the environment variable NZXL. If it is not found then NZIP will look for the ASCII file NZIP.EXL along the DOS path. If neither are found no exclude files are used as default. You can now also UNZIP files and View the currently named Zipfile. Unzip uses an 'outpath' variable which I'll explain under <CRTL><F3> key. Some people also asked where the help file was. I excluded it because some other people told me it was really of no use. But since it was asked about I put it back! WHAT'S NEW IN 2.01: The only thing that I changed from version 2.00 to 2.01 is the access of empty directories. When I first wrote NZIP I had a 10Meg drive with only 5 or 6 dir- ectories on it. When you changed paths NZIP would look to see if there were any files present along the specified path and if no files were found in the directory it would report that the path was not found. I couldn't really think of a reason to enter a directory with no files and then when I updated the versions I forgot that I implemented directory changing in this way. I changed that so you can now go into empty directories if you are so inclined. The general way things work in regards to /PATH and *Wildcard input has been changed. All file name inputs are searched along the DOS path or, if a directory structure has been obtained, across the disk. I'll explain this under the functions this pertains to. There is a second menu acces- sible through the <PgUp>/ <PgDn> keys. All the functions on the menus have corresponding <Fx> or <ALT><Fx> key strokes. Registered copies and any updates can be sent for (with a small donation) to the below ad- dress. The only function not available in the unregistered version is the ability to do different archive formats. (Keep a 4.77 Mhz PC Alive!) The command line for NZIP is : NZIP [configuration file || ? || #] [marked list file || ? || -xd] [*.zip file] All of the parameters are optional. If no parameters are passed NZIP runs with these defaults: Archive method: PKZIP Action: Update Menus: Active Directory Struct: Active The [#] parameter sets the default Archive method and uses the environ- ment vari- ables listed above if present. The Archive method is searched for on start up in the current directory and on the DOS path as: 'n' or 1=PKZ*.EXE or .COM 2=ARC.EXE or .COM 3=PKP*.EXE or .COM 4=LH*.EXE or .COM 5=ZOO.EXE or .COM A default 'Exclude' file list is also looked for upon start up when using PKZIP. The default is 'NZIP.EXL' which can be anywhere upon the DOS path. If the environment variable 'NZXL' is set then this is used instead. The variable 'NZXL' can be a wildcard which will be searched for on the DOS path or in the directory specified. In this document file I assume PKZIP is being used. Any reference to the extension '.ZIP' or 'zipfile' or 'PKZIP' is interchangeable with the other archivers supported. If there is only one parameter then the menu of directories appears and the default is used. If the [marked list] and/or the [*.zip file] appear then a command line version of NZIP is run with the configuration chosen. When file parameters are loaded off the command line they must be either in the current directory or along the DOS path; a directory structure is never obtained in the command line mode. Using either an 'N' or 'n' as the [config file] or [marked list file] will disable them. When used as a [config file] the default (PKZIP) is run with Update active. The [configuration file] is created with NZIP and can be named anything you like and can be anywhere along your DOS path or in the current di- rectory. NZIP 2.00 cannot read the older config files created with previous NZIPs. If you do not specify an extension then '.CFG' is as- sumed. If you do not specify a config then NZIP will run with a de- fault. The default archiver name is PKZ*.COM or PKZ*.EXE and can be anywhere along your DOS path or in the current directory. I will ex- plain saving configurations when I discuss key <F3> below. The [?] option used as the first parameter will give an explanation of NZIP and then exit back to DOS. The file NZIP*.DOC must be somewhere along your path or in the current directory to obtain the help. The file is a standard ASCII file that may be viewed from any editor. The help file included with NZIP is the .DOC file itself. You can create your own (using standard ASCII format) and save the file as NZIP*.DOC i.e., NZIPHLP.DOC, NZIPH.DOC, etc. NZIP displays 23 lines before a pause. The first file that matches the NZIP*.DOC file spec is used for the help screens. Hitting <ESC> during any key pause will exit the help and return to DOS. If no file is found you will be prompted for a keystroke. If you hit <RETURN> NZIP will run the menu version with default configs. Any other key will exit the program. I've included an example help text in the file NZIPHLP.DOC. If it is the first (or only) file that meets the NZIP*.DOC spec it will be used for the help screens. The [?] used as the second parameter will show the settings for the named [configuration file]. Use 'NZIP n ?' or 'NZIP # ?' to see the default specs. The [-d] option will turn off the obtaining of a directory structure when using NZIP's menus (see <F4>). The [-x] option only works when a [*.ZIP] file has been specified as a third parameter. This will allow NZIP to run with windows but the output specified in the [config] is overridden by the [*.ZIP]. The [-x] and [-d] parameters can be in place at the same time i.e., [-xd], [-dx]. The [-x] and [-d] parameters will not allow NZIP to run in command line mode and always produce menus. The [marked list] file is an ASCII file of pathnames, files and/or wildcards saved with NZIP or anything you like. If you don't want a marked list file place an 'n' in this place. If you want to use a marked list with the default config- uration then use 'n' for the [con- figuration file]. The [marked list file] can be in the current direc- tory or anywhere along the DOS path. If no extension is specified then '.MRK' is assumed. If you select an 'n' then no marked list file is read and actions are performed with the config (which will result in an entire directory being Zipped if Update is chosen). The [*.zip file] is the name of the ZIP file to output to. If this is not specified then the ZIP file in the configuration is used. If no ZIP file is specified there the program will exit. The [*.zip file] takes precedence over any files in the configuration. The '.ZIP' in the filename is optional. If another Archive method is chosen the appropriate extension is tagged on. If for some reason PKZIP cannot be called an error message will appear. NZIP needs 271K free for its data and to give to PKZIP. If there is not enough memory for the shell then an 'Insufficient memory error' is flagged. The [*.zip] file is not searched for upon start up and it is assumed that if no directory is specified in the name you want to create a new file in the current directory. Some examples of NZIP command lines: NZIP :Will run NZIP with Defaults and menus. NZIP 2 :Run NZIP using ARC as the Archive method. NZIP ? :Will display the documenta- tion of NZIP and exit back to DOS or run with menus. NZIP nz :Run with menus using NZ.CFG configuration. NZIP nz ? :Show settings for NZ.CFG. NZIP nz myfile :Run command line NZIP with settings in NZ.CFG using MYFILE.MRK as the list of files to ZIP. The output goes to the .ZIP file spec- ified in NZ.CFG. NZIP n myfile :Run command line NZIP with default settings using MYFILE.MRK as the lists of files to ZIP. Will NOT run because no .ZIP file will be specified. NZIP nz myfile newzip :Use command line NZIP to create a ZIP file using the settings in NZ.CFG, the list in MYFILE.MRK but send out- put to the file NEWZIP.ZIP. NZIP n n ZIPPY :Use command line NZIP to per-form update of entire directory, using the default configuration and send out- put to ZIPPY.ZIP. NZIP n zippers ZIPPY :Use command line NZIP to up- date ZIPPY.ZIP with file list in ZIPPERS.MRK. NZIP nz -d :Run NZIP with menus but do not obtain a directory structure on start up. NZIP n -x ZIPPY :Run NZIP with default con- figuration, menus and direct direct output to ZIPPY.ZIP. NZIP nz -xd ZIPPY :Run NZIP with NZ.CFG, no di- rectory structure menus and redirect output to ZIPPY.ZIP. NZIP 4 -xd ARCER :Run NZIP using ZOO archive method, with menus, no di- rectory structure and send the output to ARCER.ZOO. NZIP 5 myfiles C:\DUMP\NEWARC :Run command line NZIP using LHARC format, archive the files listed in MYFILES.MRK, and send the output to: C:\DUMP\NEWARC.LZH. THE MENUS If the [marked list] parameter does not appear in the command line or a [-d] or [-x] do then: The first thing NZIP does is read and sort the current directory. The number of files found is displayed in the top right. Three tables of files are shown--the arrow keys move the highlight bar amongst the files;<PgUp/PgDn> scrolls through the directory. To mark a file for zipping hit <RETURN> when the highlight is on it. Unmark works the same way. The function keys are used to open windows and change screens. <ESC> will always close a window and will exit the program. When a small input window is waiting for input <RETURN> will accept the de- faults specified or will clear the input. I will specify which routines are cleared and which obtain defaults. If you change your mind about using the function hit <ESC> to close the window immediately. When entering file name input (retrieving a marked list, naming an editor, etc.) the rules that apply are: A wildcard can always be passed unless specifically noted otherwise. If you are looking for, say, a marked list file you can enter 'ZIP1*'. The current directory is then searched, then the DOS path, then the directory structure if it has been obtained. Different functions will append the file extension as required (.CFG for configs,.MRK for marked lists,.EXE for executable programs, etc.). When passing wildcards the first match found is assumed correct and is used as the input. If you specify a drive or directory designation with a wildcard then only that particular directory will be searched. If no wildcards are input and no extension is given an appropriate ex- tension is added and then the search commences in the current directory, DOS path and directory structure. If no wildcards are input, the input contains a drive and/or directory, and no extension is given an extension is added and the directory searched. If there are no wildcards, a drive and/or directory designation and an extension the input is left intact. If a [-d] was not specified then NZIP will search and obtain the direc- tory structure of the current disk which is then used for searches and moving around the disk. The <F-> keys are used thus: <F1>--Brings up a small help menu which explains the function keys. Moving the highlight to the item or hitting the <Fx> key will execute the function. The PgUp/PgDn keys changes between the <Fx> keys and the <ALT><Fx> and <CTRL><Fx> key combos. To execute a function move the menu bar down and hit <RETURN> or use the specified key. <F2>--Toggles the directory sorting from alphabetical by name to alphabetical by extension. When the marked file list grows to over 100 entries this can become quite slow, I am working on a better (faster) algorithm. <F3>--Brings up the Archiver settings menu. There are five windows here, the one you see being specified by the type of archive you are doing:ARC, ZIP, PAK, ZOO, LZH. There are two windows in the archiver settings. The top window includes: The name of the zipfile actions will be performed on. The name of an editor to call. The location of the archiver. The name of the zipfile is the output for PKZIP. Wildcards cannot be used since NZIP assumes the creation of a new .ZIP. The default clears the name. When you change the name of the Editor or the Archiver a wildcard may be used i.e., PKZ*. If no extension is given .COM or .EXE is assumed. If a directory structure is obtained then it is searched if a match is not found in the current directory or on the path. NZIP tries on start up to determine where the archiver is on your disk. If it isn't correct you can enter anything you like. You can enter something like 'zip' if you renamed PKZIP.EXE to ZIP.EXE. Hitting <RETURN> will leave the '.EXE' name intact. The name of the editor can be entered the same way the Archiver name can be. If no extension is given .EXE or .COM is assumed. The memory requirements remain the same as that for the calling of PKZIP so choose whichever editor will fit. NZIP attempts to pass the [marked list] file to the editor. The [marked list] is always rewritten before the call to the editor and does not have to be saved prior. Choose an editor which will accept a file spec on the command line i.e., TED.COM, LIST.COM, VDE, etc. Hitting <RETURN> clears the editor name only on this screen. If you specify '%ENV' for the editor name then the environment variables are used throughout NZIP. Any other environment variable will be processed at run time (such as '%EDITOR' or '%WP'). Always precede environment variable references with a '%'. If '%ENV' is specified then NZIP will look for the environment variable 'EDIT' before calling the editor. The <F7> key will allow you to load other configurations. The file can be anywhere on the path or in the current directory. If a directory structure has been obtained it is checked if the file is not found.If no extension is given then '.CFG' is assumed. The <F8> key will save the configuration file. The default is the configuration that was last loaded. If none have been loaded the default is NZIP.CFG placed in the current directory. <F9> key here (as on the directory menu) will execute the zip command with the options just selected. You can save as many different configurations as you like to do specific tasks and the call them up again at the command line of NZIP. The <F10> key will jump between the two menus. Most of the functions that I know of in the archivers are represented here. Arrows will move the highlight around the menu;<RETURN> will toggle the option through whatever different values it can have. The only active default is the Update file option. Some functions cannot be used with others (like View ZIP and Update ZIP or Move and Update) at the same time. Some functions have been left out since I had some difficulty executing them correctly. The 'Path to Temp' and 'Password' functions default to clearing the entry. The 'Path to Temp' specifies where PKZIP will put its temporary .ZIP file. An environment variable can be used or if '%ENV' is specified in the editor name the environment variable 'TEMP' is searched for at run time. Note for PKZIP: There are two 'View' options on the menu. The view option in the lower portion of the left column views files specified as wild- cards. The view on the right, above the other view options, views the entire ZIP. <ESC> closes the window and returns you to the directory menu. <F4>-- Change the current directory. If you did not specify the [-d] option when you first ran NZIP then a list of directories appears and you select with the highlight. <RETURN> selects the highlight,<PgUp>/ <PgDn> scroll the list,<ESC> will close the window without change. If you did use [-d] then you are prompted for the directory. The new directory is searched and sorted. All marks remain intact. If no directory structure is active both <RETURN> and <ESC> close the window without change. <F5>-- Save a copy of the marked files listed to an ASCII file. The file will contain the paths and file names of all files and wildcards that are being used to archive. When an action is performed the file will be automatically saved with the most current updates. If you do not specify an extension then '.MRK' is assumed. The default is the last marked list loaded. <F6>-- Load a copy of marked files from a previous session. When this is done the loaded list is appended onto the current list. If the same file is loaded twice then two copies are in the marked list. You can load as many lists as you want to create an even bigger list. This list is automatically saved as the last file name loaded unless changed with the <F5> key. '.MRK' is the assumed extension if not specified. <F7>-- View all files and wildcards currently marked. <F8>-- Insert wildcard strings into the marked list. This allows up to 20 wildcards to be passed to PKZIP along with any files you have marked. Press <RETURN> next to any number on the menu you would like to change. The wildcards are directory specific so if '*.*' is entered while in the C:\UTILS directory the wildcard becomes 'C:\UTILS\*.*'. If the wildcard contains a drive or directory reference it is left unchanged. The default input is to clear the entry,<ESC> will leave the entry unchanged. <F9>-- Create zip file. This uses the current configuration to execute whatever action specified by calling the archiver. <F10>--Change current zipfile. Preform actions on a new zip file. This is the .ZIP file that will be used in execution. This function does not search for the ZIP file on disk but assumes you are creating a new one so wildcards are not allowed. The default is to clear the zip file name. <ALT><F1>--Show information on file. Shows the path\file, date, time and size for the highlighted file, the memory left to NZIP, the number of files to archive and the total number of bytes to archive. <ALT><F2>--Will show all *.ZIP,*.ARC,*.PAK,*.LZH,*.ZOO files on disk. If a directory structure has been obtained then all directories are searched otherwise only the DOS path and the current directory are searched. Move the highlight bar to an entry and hit <RETURN> to make the file the active one. <ALT><F3>--Change format between .ZIP, .ARC, .PAK, .ZOO and .LZH. <ALT><F4>--Change from directory structure to manual input and vice versa. The directory structure is read once if it hasn't yet been. Use this to input changes to floppy disk directories, etc. <ALT><F5>--Mark batch. Mark a group of files in the current directory by wildcard. The input must be a valid DOS wildcard such as '*.DOC' or '*.EXE'. The default is '*.*'. The wildcards are directory specific. Depending on the orientation of your last <PgUp>/ <PgDn> the marks will be rewritten immediately or after another keystroke. <ALT><F6>--Unmark batch. Works the same as Mark batch but in reverse. <ALT><F7>--Edit mark list. This function will compile the [marked list] and any wildcards, save them to the last [marked file] name given (if one hasn't been loaded NZIP writes its' own called MZIP.MRK), and calls the Editor specified with the file as part of the command line. Use an editor where this is valid;the editor should have a syntax like: C>EDIT filename If no editor name is given or the name is given as 'SHELL' then a DOS shell is executed. <ALT><F8>--Editor name. If no extension is given .EXE or .COM is assumed. If no matches are found the name doesn't change. If you enter 'SHELL' a DOS shell is executed instead of an editor. The default is the last editor name specified and can only be cleared via the Zip settings menu. You can enter environment variables here, a special case being '%ENV' which causes NZIP to check for the defaults listed above. Any other environment variable will be processed at run time. ALWAYS include a '%' before the input of an environment variable. <ALT><F9>--Zip output path. Input the path that you want the output file to go to if it is not as specified in the Archive Name. The default is the current directory. You can specify environment variables (preceded by a '%') or if the editor name is '%ENV' NZIP will use the variable 'NZOUT' is set by the system. <ALT><F10>-Obtain Archive name. If no extension is specified then the default extension of the Archive format is used: .ZIP,.ARC,.PAK,.ZOO,.LZH. This will search the directories. The default is to clear the Zip file name. <CTRL><F1>-Call the archiver's help screen. This is equivalent to 'PKZIP ?' or 'ZOO H'. <CTRL><F2>-Un-archive. This function allows the unpacking of an archive. The un-archivers are searched for as: PKUNZ*.COM or .EXE for PKZIP PKUNP*.COM or .EXE for PKPAK ZOO.COM or .EXE for ZOO LH*.COM or .EXE for LHARC ARC.COM or .EXE for ARC along the DOS path. The archive to UNZIP is the current ZIP file. The output goes to the directory specified by 'UNZIP Output' <CTRL><F3> or by the environment variable 'NZOUT' if it is defined and the editor name is '%ENV'. <CTRL><F3>-Unzip output path. Specifies where to put files extracted from an archiver. You can input an environment variable (preceded by '%') or if '%ENV' is set in the editor name the variable 'NZOUT' will be used if found. The default is the current directory. <CTRL><F4>-Get new directory structure. You can have five directory structures active at time. If you try to access another you will be asked to replace one. The first directory structure listed cannot be replaced (the start up dir). You can enter 'D:' or 'd:\' or 'd' etc. You can toggle the active structure with the <ALT><#> keys (1..5) or <CTRL><F6> which shows you which drives have been accessed and lets you choose from a menu. The new structure is then used when the <F4> is used and becomes the structure used in searches. <CTRL><F5>-Delete a directory structure. Removes a directory structure from memory. The first directory structure (start up) cannot be removed. <CTRL><F6>-Change Directory Structure. Allows you to choose from a menu the directory structure you would like active. <CTRL><F7>-Load exclude list. You can call in an exclude list to be used with PKZIP to exclude files from ZIPPING. The name can be a wildcard or environment variable. The name is searched for along the DOS path or active directory structure. The default extension is '.EXL' if not specified. <CTRL><F8>-Show and Edit Exclude list. This will show the exclude file list and allow you to change the list (up to 20 names). The input works the same as for wildcard input. <CTRL><F9>-Save exclude list. Saves the current exclude list to the file specified. <CTRL><F10>-Quick View. The function calls the archiver with the 'View' command for the named archive. The program is fairly simple to use. You can cross directories, save the marked lists and save the configuration for future use. If you like this program you can donate $20 for a registered version (it calls ARC, LHARC, etc.) and updates as soon as they are made. I would like to here from anyone who has tried this program. I can be reached via Compuserve (76106,572) and area BBS's. Please tell me about any enhancements you would like to see. Enjoy!
