Some suggestions were made and they have been implemented as follows: DWDT.EXE: 1). There is only one entry field for filename and switches. 2). Entry field now allows <esc>. 3). Pressing F10 now accepts the entry. 4). From the command line a help screen can be displayed. 5). The file list can now be removed from memory during program execution. removed 6). Clock from calendar window. DWCOPY.EXE & DWMOVE.EXE: 1). Error checking for invalid [source] filename and [destination] filename has been improved. INIT.BAT: 1). Will now compensate for the existence of [\DW] directory. See the program(s) descriptions beginning on page of [2]. Spelling has improved.<g> Billing method from Compuserve had to be changed, therefore a new ID was issued and is listed. If anyone experienced any problems, I apologize. * * * Files contained in DWPROG11.ZIP * * * 1). BW.COM 2). DESCRIER.TXT 3). DWCOPY.EXE 4). DWDT.EXE 5). DWKEY.EXE 6). DWMOVE.EXE 7). DWPRIME.EXE 8).

[2]. ──────────────────────────────────────────────────────────────────────────── ============= DESCRIPTION - quick & simple ============= *** All programs require MS-DOS v3.3 or greater. 0). Init.Bat Used to copy the program files from a floppy diskette to the hard drive. It assumes [drive A:] as the source drive and [drive C:] as the target drive. You may change these defaults by assigning a different source drive and target [drive\dir] to the variables; set SDRV=A: change [A:] to your choice for [source] drive set TDRV=C: change [C:] to your choice for [target] drive set DWDIR=DW change [DW] to your choice for [directory] NOTE0: Ensure "BW.Com", "DWCopy.Exe" and "DWMove.Exe" are on the disk with "Init.Bat". NOTE1: These programs do not require "Init.Bat". Supplied only to help the user if the user copies the files to a floppy diskette to give to another user for a trial run. 1). DWPrime <enter> Nothing more than a prime number generator. All calculations are saved to a text file named 'Prime.Txt' by default on termination of the program if in fact there are results to save. You may save your results during execution after which those results will be removed from memory. If the range of integers to calculate runs out of available memory the program will terminate and save what results are in memory at that time to 'Prime.Txt'. If this occurs, there is no call to sort those results. They will be saved in descending order. NOTE0: For large ranges I do not recommend executing the program from a floppy due to the proportional growth in file size to results that will be saved. 'Prime.Txt' can grow rather large when calculating large ranges! Approximation: 23,400 integers to find prime can produce a file 'Prime.Txt' of 1.3Mb! This of course depends on your available memory which will be different from mine. 2). DWKey <enter> More of a programmer's utility to show the ASCII & xSCAN codes of keys pressed. Their decimal, hexadecimal, octal, and binary equivalents are displayed along with the status bytes of toggle keys pressed. [3]. ──────────────────────────────────────────────────────────────────────────── ============= DESCRIPTION - continued ============= 3). DWMove [-/]? <enter> ...for syntax/help screen. A file(s) mover. If 'moving' file(s) to a floppy 'DWMove' will detect when & if the floppy is full and prompt you to insert another formatted diskette to continue 'moving' the file(s). Depending on the file(s) attributes some files will not be moved. 'DWMove' will notify you of this -> [access denied] and the 'move' process will continue. NOTE0: 'DWMove' makes no distinction if it is 'moving' files over file(s) of the same name so keep this in mind. NOTE1: redirection is allowed. 4). DWCopy [-/]? <enter> ...for syntax/help screen. A simple file(s) copier. Basically the same as 'DWMove' without deleting the source file(s). If copying to a floppy diskette it also will detect if your diskette is full and will prompt you to insert another formatted disk so the 'copying' process can continue. NOTE0: 'DWCopy' also makes no distinction if it is 'copying' file(s) over file(s) of the same name so keep this in mind. NOTE1: redirection is allowed here also. 5). DWDT [/?] for a help screen. Changes a file(s) date & time stamp. Maintains a list of the file(s) changed and of any file errors during the program's execution. This list can be viewed anytime or sent to your printer or removed from memory. It assumes your your printer is connected to [LPT1]. A calendar window was added so the user can view a calendar represent- ation of a given month and year: ( legal range for Month=[1..12] and Year=[1980..2099] ). At this time it doesn't perform any other function than to let the user view a calendar. A status line will be displayed with available function keys and their functions. There is only one input field that accepts the following parameters and their formats: [Filename] [/D Month/Day/Year] [/T Hour:Minutes:Seconds] [Filename] [/D 00/00/0000] [/T 00:00:00] You may press <esc> from the input field at anytime to escape your entry or press F10 to accept. [4]. ──────────────────────────────────────────────────────────────────────────── During execution F1 will display the following help window (shown below) and explains what is expected in the entry field and their valid ranges. You may also type: C:\>DWDT /? <enter> this will display some help text before actually beginning the program if you prefer. To begin DWDT type: C:\>DWDT <enter> -[Help·F1]------------------------------------------------------------ The entry field accepts the following format: [Filename] [/D Month/Day/Year] [/T Hour:Minutes:Seconds] [Filename] consists of a valid [drive+colon], directory name and a valid filename. Wildcards are accepted. Example: C:\AUTOEXEC.BAT /D 01/01/1993 /T 11:00:00 [/D] Components of the date must be separated by a "/" and within the valid range for each component. Valid ranges are: Month = [1..12] Day = [1..31] Year = [1980..2099] [/T] Components of the time must be separated by a ":" and within the valid range for each component. Valid ranges are: Hour = [0..23] Minutes = [0..59] Seconds = [0..59] You may enter a "Date" or "Time" or both. It is not required that you enter either. By not entering these the list will show the file(s) current date and time stamp. The status line shows available keys you can use while entering the parameters. You may press <Esc> to exit from the entry field or F10 to accept your entry. -----------------------------<Esc>·Clears------------------------------ [5]. ──────────────────────────────────────────────────────────────────────────── EXAMPLES ON HOW TO PATCH COMMAND.COM Make sure you have a backup of the original 'Command.Com' safely stored on a floppy (a good boot disk is recommended) before you patch the file. The next few pages will show you how to patch your 'Command.Com' file in case you wanted to substitute 'DWCopy.Exe' for the DOS internal 'Copy' command. You can still use the DOS 'Copy' command even after you patch your version of 'Command.Com'. Examples listed are for DOS 'Command.Com' versions 5.0, 4.0, and 3.3. There is syntax listed in the examples that you DO NOT type in. It is placed there only to guide you through using 'Debug'... <type then enter> This means you type in what is to the left of the statement and then press <enter> or <return>, depending on how your key is listed on your keyboard. ; Statements separated by a semicolon are there for an explanation only. In case you are unfamiliar with 'Debug' this will help you to understand what is go- ing on. "NEWN" This is the new name you are replacing the DOS 'Copy' command with. You can use whatever name you want but ONLY 4 characters, no less. As long as it is in upper- case then you can type this name at the DOS command line and still execute the internal DOS 'Copy' command. Example: C:\>NEWN [D:\][source filename] [D:\][destination filename] This will execute the DOS 'Copy' command as before your patch. After you patch the file and if you rename 'DWCopy.Exe' to 'Copy.Exe' then when you type... C:\>COPY [D:\][source filename] [D:\][destination filename] ...you will actually be executing 'DWCopy.exe' instead of the DOS internal 'Copy' command. [6]. ──────────────────────────────────────────────────────────────────────────── { Debug commands you will be using } R ;we need to display the contents of the CX register to get the length of the file. S ;we need to search a block of memory for the string of characters "COPY" D ;we want to display the contents in memory so we can see the string of characters "COPY" E ;we need to enter the string characters to replace "COPY" at the correct address... the address [S]earch will return. L ;we'll load the recently replaced string of characters and see if they are there. W ;write the file back to disk. Q ;quits the 'Debug' program. NOTE1a: The important thing to remember is the offset address returned after executing [-S]earch. I suggest you study the examples before you begin if you are not familiar with 'Debug'. It is actually quite simple. { the offset addresses for the 'Command.Com' versions I tested. } A93B offset for "COPY" 'Command.Com' v5.0 81DC offset for "COPY" 'Command.Com' v4.0 54CB offset for "COPY" 'Command.Com' v3.3 I do not guarantee that the addresses will be the same or that these examples if followed will constitute a successful patch by you, but they are indicative of what you can do.

If you have two copies of 'Command.Com' on your hard drive then make sure the patched version is copied over each. Place 'DWCopy.Exe' in your DOS directory and rename it to 'Copy.Exe'. Now reboot your system so your patched 'Command.Com' can be reloaded. Now, anytime you execute 'Copy' it will be 'DWCopy' that is executed. You can still use the DOS 'Copy' command, as long as the 4 characters you replaced it with are uppercase, by entering the name of whatever you patched it to. ──────────────────────────────────────────────────────────────────────────── ──────────────────────────────────────────────────────────────────────────── Make sure DOS can find these files through your Path statement. Your [\DOS] directory is good place for "DWMove.Exe" & " DWCopy.Exe". All programs were tested on IBM compatibles 8088-486, color and mono, using MS-DOS versions 3.3 thru 5.0.
