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 20 S$=STR$(I%*I%) 30 PRINT S$ 40 RESTORE 50 REPEAT 60 READ A$:IF A$="99" THEN PRINT"Note the displayed value"'"then press any key":G=GET 70 X%=0:T%=0 80 REPEAT:X%=X%+1 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.

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 of programs 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 are required for the DFS version due to the large 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 setting up. 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. If you want to hear sounds effects you should introduce further amendments in lines 370, 1410, 1470, 1530 and 1900. 370 FOR N=1TO100:SOUND1,-12,100+RND(2 00),1:NEXT 1410 FOR N=200TO10STEP-4:SOUND1,-12, N,1:NEXT 1470 SOUND0,-12,20,5 1530 FOR N=1TO20:SOUND0,-12,N,2:NEXT 1900 IF POINT(X,Y)=2 SC=SC+1:SOUND0, -12,20,3 Met hartelijke groten, Mirek.

Just to remind you all, the info at the start of the game says that the arrow keys can be used for movement too.  To: 999 (all members) From: 2J3 (Chris Richardson.) Subject: ONERROR I discovered something whilst checking out issue 33 for BBC compatibility. The ONERROR in the cassette database "CasTore" (I nearly called the datafile "oil" by the way) causes the BBC version to miss the next line out. This happened to be H%=1 which caused one part of the screen not to be printed as H% 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 is towards 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 any particular 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 Competition Ok! I get the message.
