I, for one, would appreciate more explanation and an example. What is the purpose of the program? What is the definition (via a link) of an integer partition? For instance, something like: "A partition of an integer, n, is one way of writing n as the sum of positive integers where the order of the addends (terms being added) does not matter....". That was taken from this link, which seems to provide a good introduction to Partitions of Integers.

What is the practical application of this program? Also, there is a way to enter the program in a 'scroll-box' so it is not so long on the screen.

RE: HP 35S Partitions
To post #2:

Purpose: to calculate the number of 2 different types of integer partitions.

Example: one integer partition of "5" is "4+1"

Definition: adequately supplied by the sentence in quotes & the suggested link

Utility: I am not principally interested in usefulness but much rather in improving the programme. Should anyone become rich through using the programme I would ask them not to inform me.

Scroll box: I find the full screen depiction of the programme gives a better overview.

Should the article promote some research, interest, discussion....& improvements to the programme it will have fulfilled my needs.

Thank you for your comments.
