How to Get Our Programs Up and Running
Each article in this issue with a disk icon on its first page (or next to its title on the Table of Contents) has a companion file on your START disk. These files are archive files--they've been compressed with the Archive Utilities Set, or ARC, a public domain program available for many personal computers. We use the ARC utility to squeeze the many files that may go with a particular article into one compressed file, which may be only 40 percent of the total size of the original files.
In addition to the archive files, you'll find the program ARCX.TTP, which stands for ARChive eXtract, on your START disk. You'll use this program to decompress, or extract, the disk files we've shrunk down with ARC.
All programs on your START disk are copyrighted. They are for your own private use, and are not public domain.
Un-ARCing the Files
To use START's compressed disk files, please follow these steps:
1. Copy the ARCed file you wish to use and the program ARCX.TTP from your START Backup disk onto your second blank formatted disk. When you're finished, label it UN-ARC disk.
2. Now you'll extract the compressed files from the ARC file you just copied. Insert your UN-ARC disk into Drive A. If the Drive A window is already open on the Desktop, you can press the Escape key to see the new disk directory. Otherwise, double-click on the Drive A icon to see the directory. Double-click on ARCX.TTP. The following dialog box will appear:
3. Type in the name of the ARC file you just copied over to your UN-ARC disk and press Return. You do not have to type in the extender.ARC. You can type in the name in upper or lower case.
(Note: If ARCX.TTP can't find a file, it may be because you have misspelled the name of the ARC file. You must type the filename exactly as it appears in the directory.)
4. As the program runs, it will display the names of the individual files as it extracts them, similar to the example below.
When ARC has successfully extracted all the files, it will return to the Desktop and you will see the original files within the directory window, along with the archive file and the ARCX.TTP program. You may now use any of the START files as you wish; just follow the instructions in the appropriate article in this issue.
To use any other archive files on your START disk, simply repeat the above procedures. Be sure you begin each time with a blank, formatted disk.
In addition to the runnable programs, some ARC files may also contain source code listings or an ASCII text file (called BREAKDWN.TXT, for example) which describes the program's structure. You can examine such a file from the ST Desktop by double-clicking on its icon and then clicking on Show (to see it on the monitor) or Print (to print it out).
