LEARN BASIC WITH YOUR HANDS ON THE KEYBOARD, NOT WITH YOUR HEAD IN A BOOK! Now '~ you can learn ZX BASIC programming with your Spectrum. 'Interactive BASIC Programming ' is a unique '>:·1 package in twelve parts, Look at these features: ~-3 Plain English (yes, real English not jargonese). Due to an amazing programming technique you will have complete control over ~_:'.· Spectrum BASIC. So you can write, save and load programs while using 'Interactive BASIC Programming'. All ZX BASIC is covered. You'll learn about graphics (see some on this ad), colour, sound, motion, system vari (:'i>) ables, menus and much more, explained simply. Problems are given with hints and answers in the form of programs that are put into BASIC for you to look at, run and alter. You'll learn how to write your own games (byway of examples) and how to put your machine to serious use (e.g. graphs, problem solving, filing system). More than 250K (yes, two hundred and fifty kilobytes). After sales support at no additional cost: write or telephone if you have any questions about Spectrum BASIC.

He wants me to prove that I understand the Spectrum. He claims he only bought the machine because I told him it would turn me into a computer programmer. Showing great patience, I explained that the Spectrum HAD been educational; it had taught me that thinking you needed to be a programmer in order to use a computer was like thinking you needed to be a mechanic in order to drive. Using it to zap aliens, as he correctly described my habits, was the true, progressive way to employ the device. I also told him I couldn't have got this job writing for Sinclair Programs if I didn't know SOMETHING. He said that all I knew was my sister, "a computer virtuoso" troii)- I decided that if I write a music routine then even someone . , ~f,- of Dad's generation would be able to understand the skill involved - -' and it would be handy for the magazine. ' After some lengthy sessions where I explained the principles involved to my little sister Eustacia, I'd sorted out the main part of the program. As I told her, the first line dimensioned an array which would be filled, in line 2, by the values of the notes contained in line 4. Lines 30 and 32, meanwhile, sat in the main loop which created your aliens and your missiles and your smart bombs and your nuclear laser gun. 1 DIM P(100): LET P=O 2 FOR X = 1 TO 96: READ P(X): NEXT X 4 DATA ... (the values of the notes) ... 30 LET P= P+ 1: IF P= 96 THEN LET P= 1 32 BEEP .05,P(P) However, I explained, in longer programs this routine might slow thii response to key presses for the missiles and bombs and stuff. So we should stop the tune if keys were being pressed by deleting line 32, replacing line 30, and adding new lines. 30 IF NOT LEN INKEY$ OR IN 32766 = 191 THEN GO TO 100 100 IF LEN INKEY$ OR NOT IN 32766 = 191 .- THEN GO TO 35 110 LET P=P+1: IF P=96 THEN LET P=1 115 BEEP .05,P(P) 120 GO TO 100 -- This is when Eustacia shocked me very much by refusing to calculate the DATA 1 values for line 4 - even when I explained how very educational she would find it. Several days later I had written line 4 as follows, 4 DATA 69,2, 14 , 13, 14,9, 12, 10, 7 ,69, - 2,2, 7,9,69,2,6,9, 10,69,2, 1,4, 13, 14,9 , 12, 10, 7 ,69, - 2,2, 7,9,69,2, 10,9, 7,69,69,9, 10, 12, 14 ,5, 15 , 14, 12,3, 14, 12, 10,2, 12, 10,9,2, 14, 13, 14,9, 12 , 10 , 7,69, - 2,2, 7,9,69,2,6,9, 10,69,2, 14, 13, 14,9, 12, 10, 7,69, - 2,2, 7,9,68,2, 10,9, 7,69,69,69 However, I made sure Dad saw me sweating over this music.
