- !Yow displays a random "fortune cooky", quotation or witicism in a
- window. The window closes when you click SELECT or MENU in it or re-run
- !Yow. Clicking ADJUST displays a new fortune. If the desktop is not
- running !Yow just prints a text to the current output stream(s).

- History
- -------
- See !RunImage for details of modifications.
-
- The name !Yow was used by Ian Rawlings <ssurawls@uk.ac.rdg.susssys1> for
- his program which inspired this one (see below) but I have pretty much
- completely rewritten it as well as greatly extending the data file
- (YowLines). I got the Garfield icons from a program called !Quotation by
- Roger Spooner, as well as some of the quotes. Ian's !Yow is available from
- the Newcastle Info-Server <info-server@ncl.ac.uk> as "fortune" and
- !Quotation is called "quote" there. Other texts come from Walther
- Schoonenberg <walther@econ.vu.nl>'s program !Cooky ("dcookie" on
- Newcastle), David K Barber (aka Nigelstache)
- <Barber_DK@P1.lancsp.ac.uk>'s program Cookie (Newcastle "cookie"),
- several versions of the Unix fortunes.dat file and a more recent file
- full of jokes mailled to me by Ian.
-
- Algorithm
- ---------
- The program originally loaded the whole file into memory, picked a
- random text by its number within the file and then searched through
- memory for the Nth text. No wonder Ian thought he wanted a better
- compiler, what he actually wanted was a better algorithm!
-
- The program now sets the file pointer to a random byte offset within the
- file and searches back from there for the start of a text (or the start
- of the file). This is more likely to pick a long text than a short one
- but this bias can be reduced by a tweak in !RunImage which is currently
- commented out. A window is created in the middle of the screen and the
- text is printed in it, breaking lines at spaces if necessary.
-
- Sort & Gen programs
- -------------------
- Two other programs are included in the !Yow application directory.
-
- "Sort" sorts the data file to make it easier to spot duplicates when
- merging a new file of texts.
-
- The second program, "Gen" is based on an idea from Scientific American.
- It generates random sequences of characters based on the frequency of
- occurence of strings of n characters in some example text (YowLines in
- this case). The parameter "n" (Mem%) determines how many previous
- output characters the program remembers in order to choose the next one.
- If n=4 say, it searches YowLines randomly for an occurence of the last
- three characters output, looks at the character following them in the
- file, outputs it and shifts it onto it's memory FIFO (first-in
- first-out) buffer. The effective value of "n" counts up from 1 (an
- initial \0 output is assumed) on start-up. This process is equivalent
- to using frequency tables for all sequences of "n" characters. That
- would run much faster but would take a long time to calculate the
- tables.

- This is an Archified version of YOW on the IBM. It is one of those
- hateful Fortune cookie programs that simply plonk a phrase at random
- onto the screen, the file of phrases in this case being taken from the
- IBM side thru' PCdir. I don't know exactly who wrote the thing (apart
- from the fact that they obviously don't lead a very interesting life if
- they are prepared to sit down and write all that bumf) but the file from
- the IBM had a header that I have stripped for simplicity of programming,
- 'cos I'm not too good yet! The header is included below for those
- interested.
-
- It's American, so many of the phrases are not funny to us, and some of
- the phrases are obviously hilarious to the author but are totally lost
- on me. Still, it does throw up some gems occasionally, eg "A Liberal
- is somebody too poor to be a Capitalist and too rich to be a Communist"
-
- Due to the gumf that goes on, not even Archie basic V could get a good
- enough response time, so out of desperation I compiled it at a friends
- house using RISC basic from Silicon Vision. After the heavy editing
- necessary to get the program to compile I ended up with a 22K file from
- an original of 2.6K, it needed 64K instead of 40K to run, and it also
- needs the Floating Point Emulator loaded! It did run faster though,
- which has never happened before when using RISC basic. Usually the
- program runs slower! Could somebody PLEASE bring out a decent BASIC
- compiler?!
-
- My Bank Manager forced me to return my Memory Expansion to Diamond
- Computing. I'd only had it for a week, but it really is missed!
-
- The original header
- -------------------
- Zippy the pinhead data base. The official copy of this is in the file
- "MLY;YOW >" on MC.MIT.EDU
- Everything up to the first ascii \000 (`null') character is a comment.
- The file consits of zippy quotations (from various comic books and
- strips by Bill Griffith) followed by a null character.
- Newline chracters following a quotation are ignored and are present
- only for readability.
- Have FUN!
- This file is currently used by:
- * the FORTUNE program on MIT-OZ
- * the m-x yow command in GNU Emacs.
- * NIL (MIT Common Lisp)'s debugger
- * something bandy wrote at LLL-CRG.
