This is based on Ron Aaron's "Magic 8th Ball" - CLI version.

First is the list of responses. This is just an array.

To get a random prophecy: get the length of the array, a random
|
|
number, and calculate an index based on these to fetch.
|
|
|

|
|
:prophesy (-s)
|

PROPHESIES dup a:length n:random n:abs swap mod a:fetch ;

This finishes the core of the application. The remaining part is
|
|
the user interface. RETRO doesn't have GUI bindings, so I'm only
|
|
implementing the CLI interface.
|
|
|
|
My approach is a little different from the original. I split the
|
|
input "processing" into a separate word. RETRO doesn't have a
|
|
null string, so I left out the check for that. Exit with CTRL+C.
