Welcome.

All programs and program listings in this issue are on your START disk provided in a special envelope bound into the magazine. (If you purchased the $4 version of START, without disk, you can still purchase the disk by sending us the bound-in card or mailing $10.95 plus $2.00 for postage and handling, to START DISK, 524 Second Street, San Francisco, CA 94107.)

Use a pair of scissors to open your disk envelope along the outside vertical edge. Place your START disk into drive A and double-click on the disk icon to see its contents. Please refer to your ST owners manual if you are uncertain about proper Desktop procedures.

Your START disk contains nine folders. Each folder corresponds to a particular START article. To open a folder and reveal its contents, double-click on the folder's icon. Before running a program, we recommend that you read its related article and transfer its files to another disk. Also, it's a good idea to back up your START disk before use.

COMPRESSED FILES

Some of the files on the START disk are in a compressed format. You can identify them by a "Q" as the second letter of the filename extender (e.g., XLISP.TQP). These files are unusable unless first decompressed with the Un-Squeeg program included on your START disk. We chose the Squeeg program from Quack Computer Company as the most efficient compressor of ST files. Only the Un-Squeeg program (the decompressor) has been included on your disk. Please note that this program is owned and copyrighted by the Quack Computer Company and is not to be considered part of the public domain. The latest Squeeg/Un-Squeeg package, which includes the compression program, is available for $24.95 from:

DECOMPRESSING

To decompress a file, first transfer both the compressed file and UNSQUEEG.PRG to another disk. When run, the UnSqueeg program will create a second, decompressed file which may be more than twice the size of the compressed one. Un-Squeeg will not alert you if you run our of disk space, so make sure you have plenty of room on your destination disk.

After transfering the files, double-click on UNSQUEEG.PRG and a file selector box will pop up requesting the file to decompress. Un-Squeeg automatically searches for filenames with "Q" as the second letter of the extender Select a file to decompress and click in the OK box. Un-Squeeg responds by asking for a destination path. At this point, it is easiest just to select the default (drive A) by clicking in the OK box. The file will be decompressed and written to disk with the original, unsqueezed filename (e.g., XLISP.TQP will be decompressed and written to disk as XLISP.TTP).

As an example, we'll step you through the decompression of the XLISP program:

1. Drag UNSQUEEG.PRG to a blank, formatted disk in drive A, then open the XADVISOR.STQ folder by double-clicking on it, and drag XLISPTQP to drive A. (If you plan to go on and use the programs from the Chabris AI article, this might be a good time to drag all the files within the XADVISOR.STQ folder to drive A. There will be plenty of room.)

2. Double-click on UNSQUEEG.PRG from drive A to run the Un-Squeeg program.

3. The Un-Squeeg program will begin with a file-selector box requesting a file to decompress. Click and highlight the file XLISP.TQP, then click in the OK box.

4. Un-Squeeg will respond by asking for a filename to write the decompressed file to. The filename will default to XLISP.TTP on drive A. For this example, select the default by clicking in the OK box.

5. The file XLISP.TQP will be decompressed and written our as XLISP.TTP. When the Un-Squeeg program is done, it will query you for another file to decompress. Click in the CANCEL box to exit to the Desktop. The decompressed XLISP file, XLISP.TTP, will now be on drive A and ready to run

ADDITIONAL INFORMATION

Detailed information on batch files, program compilation, and program assembly is contained in the README.TXT file on your START disk. All Programs were compiled and tested on a 520 ST with TOS in ROM, using the Atari Developer's Kit.
