- INTRODUCTION:
- =============
- UU-encoding is a way to code a file which may contain any
- characters into a standard character set that can be reliably sent
- over mail networks like USENET or FIDO.
- The UU-encoding and decoding is adapted from the UU402.C
- sourcecode we found on an ATARI Unix machine.
-
-
- HOW TO USE:
- ===========
- The UUCODE.APP for the series 3 contains the functions for
- uuencode and uudecode, which means it can encode a binary file or
- decode its ASCII representation.
-
- Please install the application in your system screen.
-
- After starting the application the source-code file selection will
- appear. Here you can select the required file for processing.
- The application detects automatically, if it is an UUcoded file.
- In this case it is encoded into its original file.
- If it is no UUcoded file it is automatically coded into an ASCII
- file. The UUcoded file will get the extension *.ASC and will be
- saved using the same pathname as the soucre file had.
-
-
- HINT:
- =====
- The first line of the UUcodeded file contains the target filename
- with filesystem, drive and path.
- The result of the decoding process is stored at this path.
- If there is a drive which is not present on your Series 3, then
- you should edit this, before starting the UUcode for decoding.
-
-
- ABOUT THE CHARACTER ENCODING:
- =============================
- The basic scheme is to break groups of 3 eight bit characters (24
- bits) into 4 six bit characters and then add 32 (a space) to each
- six bit character which maps it into the readily transmittable
- character. Another way of phrasing this is to say that the
- encoded 6 bit characters are mapped into the set:
-
- `!"#$%&'()*+,-./012356789:;<=>?@ABC...XYZ[\]^_
-
- for transmission over communications lines.
-
- As some transmission mechanisms compress or remove spaces, spaces
- are changed into back-quote characters (a 96).
-
- The encoded file's size is expanded by 35% (3 bytes become 4, plus
- control information), causing it to take longer to transmit than
- the equivalent binary.
