Areas A suite of programs which can be used for any Sinclair computer, devised by Ian Howland and Damian Clay of Avon These programs are a suite, either to be put individually into a 1K ZX81, or to be put in together with the menu in a 16K ZX81 or Spectrum. Each program with your measurements will work out the areas of the following shapes: _____________________________ 1 Square/Rectangle 2 Triangle 3 Circle 4 Semicircle 5 Ring _____________________________ Each program follows the same pattern. First the screen clears and then it asks for the first measurement, it then displays the measurement given and the programs:- Square/ Rectangle, Triangle and Ring ask for a second measurment. Once all the measurements have been entered and veri- fied, the screen is cleared and the formula displayed. The computer then works out the answer and displays it. If you use the menu and all of the programs, then change each set of lines which say:- PRINT AT 15,5;"Hit a key to continue" PAUSE 4e4 GOTO (1000)(2000)(3000)(4000)(5000) (depending on which routine it is in) Alter these lines to: "Press C to Carry on or M for Menu" g$=INKEY$ IF g$="M" THEN RETURN IF g$="C" THEN GOTO (1000)(2000)(3000)(4000)(5000) (as appropriate) GOTO (3 lines back) [ The TZX to which this text belongs contains both forms, first the collected routines with the menu, followed by the individual routines as separate programs - RLB. ]
