8 Bit To: 999 (all members) From: K2K (Peter Davy) Subject: A new member's first message.
I am very pleased I responded to that
advertisement for 8BS which appeared in
a recent BEEBUG magazine. I must admit
that I found it quite a challenge to
find my way around the items on the 8BS
magazine disk. I knew I needed help but
I was unsure what form it would need to
take. Now I know! The new MenRead
program on issue no.32 makes all
abundantly clear. Many thanks to the
member who asked for it and to the
editor who wrote it.
Many years ago I used to enjoy playing
with programmable calculators. I used
to search for numbers with odd
properties. I remember wondering if
there existed a ten digit number which
is a perfect square (i.e. its square
root is a whole number) and the digits
themselves comprise two of each of the
digits 0, 2, 4, 6 and 8. I wrote a
program to make the search and left it
running overnight. If a number meeting
the above requirements were found the
program would stop with the number in
the calculator display. I was delighted
the next morning to find the program
had stopped with a ten digit number
containing two zeros, two twos, two
fours, two sixes and two eights. A
quick test showed that the square root
of the ten digit number was a whole
number. At the outset I had no reason
to think that such a number existed but
now I had found one. My pleasure at
finding this number was compounded
when, as a result of running the
program to the bitter end, I discovered
that there were no other ten digit
numbers meeting the specified
requirements. The number I had
discovered is unique!
The subject of "my number" happened to
cross my mind recently and I decided it
would be interesting to re-discover it
by writing a program for the Beeb. This
is the program I wrote:
10 FOR I%=44748 TO 94162 STEP 2
30 PRINT S$
60 READ A$:IF A$="99" THEN PRINT"Note
the displayed value"'"then press any
90 IF MID$(S$,X%,1)=A$ THEN T%=T%+1
100 UNTIL T%>2 OR X%=10
110 UNTIL T%<>2
120 NEXT I%
1000 DATA 0,2,4,6,8,99
Although not an overnight job, this
program is quite slow at reaching the
number sought. Members may like to
devise something quicker.
The principle of the program is to
square all the numbers between 44748
and 94162 and to test each answer to
see if it contains two of each of the
digits 0, 2, 4, 6 and 8.
A possible problem is that the Beeb
displays numbers only up to 9
significant figures and we need 10.
However we need a string representation
of the ten digit number to test it for
the presence of 2 zeros, two twos etc.
and we get this using the trick shown
in line 20 of the program. When S$ is
printed in line 30 it contains all ten
of its digits.
If you wish to know what the sought for
ten digit number is you will need to
type in the program and RUN it.
I have now finished talking about ten digit numbers! For the last eleven years or so I have written for the BBC-B (and subsequently for the Master-128) more than 140 programs for Adult Basic Education, mostly literacy but some numeracy. The programs are usable by primary and junior school children. All of my output is now available from 8BS - Catalogue numbers TBI-46-1 to 5. I am always keen to consider changes to existing programs or ideas for new ones. Please contact me if you have any suggestions.

If by any chance you have a dog and you call it Pete as the name of this one is Pittling Pete and you will find it listed as PPETE I am always on the lookout for little bits of verse and if anyone has any of them they are always welcome to send then to me.

The discs are called Masterdisk. Masterdisk has ceased trading, however Andy has kindly allowed 8BS to put the series into the TBI pool. They are available on 3 ADFS discs at the usual prices. M.Bobrowski has also sent us his version of an Acorn User Package "Poster". This is an excellent suite ofprograms to produce A4 size posters using 100 fonts borders and boxes to enclose text. A printer dump routine and full info are included. 2 Discs arerequired for the DFS version due to thelarge number of fonts supplied. 1V5 has sent a full ADFS disc of digitised pics taken from Archimedes PD. They are mostly of vintage cars. This disc is one of many that will be in the new Archimedes PD library "Phoibos" that 1V5 is very busy settingup. He reckons that things will be ready about April time. Watch this space!

However, you can easily break your fingers using the H, J, U and N keys to control the game. The only solution is to change the lines 1670 - 1673 as follows: 1670 IF Q=90 THEN anders=0:GOTO1680 1671 IF Q=88 THEN anders=1:GOTO1680 1672 IF Q=47 THEN anders=2:GOTO1680 1673 IF Q=58 THEN anders=3 With these amandments you can use the so called Snapper's keys (ie. Z, X, / and : keys) to control caterpillar movement.

To: 999 (all members) From: 2J3 (Chris Richardson.) Subject: ONERROR I discovered something whilst checking out issue 33 for BBC compatibility. TheONERROR in the cassette database "CasTore" (I nearly called the datafile"oil" by the way) causes the BBC version to miss the next line out. Thishappened to be H%=1 which caused one part of the screen not to be printed asH% was not initialized to 1. I think this was because my Master was happy with ONERROR on its own, but the BBC needed something after the ONERROR and therefore ignored the next instruction unless there was an error. The problem was circumvented by inserting a REM after the ONERROR. Further to this, the self same thing has just appeared in the program "Patterns". Funny how you never come across something and then it happens twice in 10 minutes. To: 999 (all members) From: 2J3 (Chris Richardson.) Subject: Charging. I have left discussing this subject until as late as possible so that I could get a good sounding from all members. Of the eight opinions so far expressed, 4 say put up the TBI charge.One suggestion of a yearly extra charge. Three donations. However, a better guide has been the actual payments enclosed with orders. There have been plenty of orders from the pool with most people paying what they feel like. Very few payments of 10p, most are 50p per disc. One member even sent one pound per disc for six discs including p+p and their own discs. It would seem that the general trend istowards 50p per disc with p+p and disc supplied by the member. This seems quite fair to me. However I think that not enough members have made their views known yet for me to commit to anyparticular charge. I shall leave it to you for the moment to continue voting with your payments. A decision WILL be announced in the next issue. Until then PRICES ARE AS STATED IN TBI-00. To: 999 (all members) From: 2J3 (Chris Richardson.) Subject: Prisoner's Dilemma CompetitionOk!

Which brings me to Watford Electronics (the bad guys, boo hiss...) Yes I've experienced their non-existant after sales service too. My problem is this; I use WE's Wapping Editor (and a jolly good piece of software it is) but I'd like to be able to load pages into my home-built (as per BEEBUG) 32K SWR (2x16k units) It seems that the Wapping Editor can't differentiate between the different banks of SWR and pages turn out jumbled up. If there's anybody out there who can help at all, please, please, please etc 'phone me (or message me through 8BS) my phone number is:- 081-337-4731, I look forward to hearing from you.
