%C%Inductive Logic, Iteration and Recursion

The files in this directory are here to entice you to want to read
my articles on the subjects in the title. They will appear on the
quarterly discs sent to PipeLineá4 subscribers. The custom function in
the file [c_Prime] doesn't even use recursion so the title of this
[ReadMe] is a bit of a cheat really.
To see the custom function at work double click on [Primes01].
Mathematicians and logicians (as well as computer programmers) are
interested in Inductive Logic, Iteration and Recursion and so I am
working up a series on these related subjects. My excuse for using a
'repeatá-áuntil' loop in this directory under this heading is that any
'repeat - until' can be converted into a recursive function! If you do
this and send me a copy in time for the August 1992 PipeLineá4 disc
(conforming to the conventions referred to in the last paragraph) and
if it is published then I will send you a PipeDream mug!!
Another reason for linking the words in the title is that any iterative
or recursive problem can be 'converted' to a problem which uses the
language of inductive logic and any inductive logic problem can be
converted to an iterative process. So that's my justification.
My final reason for including this directory is that I am hoping to
encourage you to send me more custom functions and I would like you to
conform to a few conventions I have discussed with Robert Macmillan of
Colton Software. You will find those recommendations in the
directories Custom01 and Custom02 of the Mayá1992 PipeLineá4 disc. The
custom function in this directory is a good example of conforming to
the recommended conventions and it is a good example of a custom
function anyway! Note that all variables are declared using set_name()
before they are initialised using set_value(). The function set_name()
is used only once when the variable is declared.
