If you have existing names in Brother's Keeper data files from version 4.0, 4.1, 4.2, 4,3, or 4.5, then you will need to run the CONVERT5 program one time in order to convert the data files into the new format used by version 5.0 of Brother's Keeper. The CONVERT5 program will read your existing data files and create new data files that version 5.0 can read. The CONVERT5 program will NOT erase or change your old data files - it just reads them when creating new version 5.0 data files. After you convert to version 5.0, and after you verify that version 5.0 is working correctly, you may remove the old version 4 data files from your hard disk if you wish. Before removing your old data files, be sure you have a copy of them on diskettes, and save the diskettes for several months in case there is any need for them. If you have used text files to hold message lines for people (if you have used $$FILENAME in a message line) then you will need to copy the text files over to the new area that contains the version 5.0 data files. You should use the DOS COPY command to copy text files from one directory to another. Before you start CONVERT5, you should know where the version 4 data files are located (what is the name of the subdirectory) and you should know where you want to place the version 5.0 data files. As an example, you might currently have your version 4 data files in a subdirectory called C:\BK and you might want to create the version 5.0 data files in a directory called C:\BK5 or perhaps you have your existing data files in C:\DATA and maybe you want to create the new version 5.0 data files in the same C:\DATA subdirectory. If you do not know where your existing version 4 data files are located, look in the subdirectory that contains the version 4 programs or look in the subdirectory that you are "in" when you start BK version 4 or 4.5. The version 4 data files have names that end with .DT4 (for example FAMLFILE.DT4). It is possible that you have FAMLFILE.DT4 in more than one subdirectory. If you do a DIR and it shows a file length of 0 (zero), then that is not the correct subdirectory. If in doubt, you may look at the file by typing: TYPE FAMLFILE.DT4 and that will display the names on the screen. When you are running BK version 4 or 4.5, the option screen number 1 will contain the "path" for the data files. If the "path" is blank, then the data files are located in the "current" subdirectory (that is, the subdirectory you start the program from.) OK, assuming you know where your existing data files are located, the only other thing you need to know is whether or not you used the "check" fields in version 4 or 4.5. If you did, then you will need to decide where to put them when you run CONVERT5. Version 5 has "source" lines for each date and location. You can have three full lines of "source" information and you also have a "page" field. If you have put information such as "yes" or "no" in the check fields, or if you have put page numbers in the check field, then you would choose to move the check fields to the "page" fields. If you have put some sort of code information in the check fields, such as "B101" which is a code you made up to refer to a "source" for the information, then you should choose to move the check fields to the first "source" line. The utility program will let you change each source to a new source - for example you could use the utility program to change source "B101" to "Barnes Family History, written by Jack Barnes, published 1982, in possession of Joe Doe". This might all be more clear after you use version 5.0 for an hour, so pick what you think is the right answer for your situation, and if you find it is not correct, you could run CONVERT5 a second time and erase the version 5 data files and pick the other choice for the check fields. To start CONVERT5, change to the directory that contains the version 5.0 programs and type CONVERT5 and enter. It will take a while if you have a lot of names. After converting, you may start BK version 5.0 by typing BK5 and enter.
