Thanks for linking this. Though I've never met Walker, I was introduced to ANIMAL around 1977 on a Univac 1108. That was after the PERVADE subroutine quit working due to the release of a new version of the Exec-8 operating system. I was working then as an 1108 FORTRAN programmer, and learning 1108 assembly. Walker's code was a great example to learn from.

I suspect the earliest versions were written in the '50s when Claude Shannon and David Huffman were working on compression algorithms.

P.S. The reason ANIMAL and PERVADE are in all caps is that the 1108 used a character set called FIELDATA http://bit.ly/10w9dwq wherein a 36 bit ~~byte, or~~ word comprised six 6 bit characters...no lower case. We thought in octal, not hexadecimal.

When they made ASCII available, there were 4 9-bit bytes to the word

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.


Come for the quick hacks, stay for the epiphanies.
