9. Claim ID: 38433 Membership Number: 37096 05 June 2003 Dear Mr Smyth Thank you for sending us the details of your recent record attempt for 'Largest Joystick'.I am afraid to say that we are unable to accept this as a Guinness World Record. Unfortunately our research team have concluded that your attempt does not conform to our manufactured articles guidelines as there is no commercially available joystick which looks like a small version of this. I appreciate that this may be disappointing to you, but I hope that this does not deter you from trying again. We are always keen to hear from people who wish to set a Guinness World Record. If you should need any advice regarding breaking an existing record or setting a new Guinness World Record please contact us again through our website or directly quoting the above membership number. Once again thank you for contacting Guinness World Records. We wish you every success with any future record-breaking endeavours. Yours sincerely, Sophie Whiting Records Research Services

40. Inputting Software Solution Assignment 2 parallelput(1) var value : int loop value := parallelget if value = ______ then put “UP” elsif value = _____ then put “DOWN” etc

41. Inputting Software Assignment 3 Write a program that will: Draw 8 arrows (compass points) and a fire button Randomly highlight one of the 8 arrows and/or the fire button Time how long it takes the user to match the prompt with the corresponding joystick movement Repeat 20 times Output the total time taken for all 20 matches ?????? Additions ??????
