@Kitonum thanks Yurii. You should get a job at Maplesoft.

@Markiyan Hirnyk Politeness? Does the idiom "pot calling the kettle black" translate in Ukrainian language?

@Carl Love thank

@Markiyan Hirnyk Now go away.

@Carl Love Sorry to bug you further, but how can the pROgGRAm be modified to output the (overall) change in mean. Eg player A1= 0, B2=-59 [round(756.6-816)],  B1=+5, A2=+2 (including the sign). Use of exports? Thankyou

@vv I have to iterate over the expression RC(...).

I'll try to explain.

A1 has been assigned an initial value of {1007,47} in "ord".

then A1 is turned into A1' via RC function {1004,45}.

this value of A1' is reused later on to become A1".

When I try to extract A1 from "ord" (using a do loop) for the lhs, i require it to be an unassigned "A1".

A1:=.....

@Kitonum and @Markiyan Hirnyk . The OP is using Maple 15. This version doesn't have Repeating Decimal command.

It does what I want, thankyou for your effort.  I don't fully understand your code, I would have to pick apart each line i suppose. For use at my next tea party no doubt!

@Carl Love what if the objective was within 10%, using the tolerance package purhaps?

@Kitonum vote up

@Kitonum

thx. I am trying to lookup the ans from set A, and output the correct answer [L/2],[S/2,M/2], but my code outputs

See output 11.

what have i done wrong?

@tomleslie Thank you. To answer your question I pretty much wanted the output to replicate the picture posted.

@Carl Love 
Thankyou. After c:= max(indices(Data, nolist));

"Error, invalid input: indices received Data, which is not valid for its 1st argument, t"

interface(rtablesize= max(26, c)):
Error, (in interface) rtablesize must be a positive integer, or infinity

I need to upgrade to M2016 I guess.

Since I posted the question I had more of a go and used SOWPODS (freely downloadable) as my dictionary. (one word length at a time)

@Markiyan Hirnyk 

OSPD3 conflates English two letter words (what I want) with abbreviations, shorthand or acronyms.

"FT" or "BP" aren't words as such but as acronyms or abbreviations have many meanings.
