RULE: A string variable name ends in a dollar sign, "$". You can use any letter you likefor the name and then put a dollar sign after it.A$ is called a variable because you can put different strings into the box at differenttimes in the program. The box can hold only one string at a time. Putting a new stringinto a box erases the old string which was in the box.ERROR MESSAGES FROM INPUTRun this three times:10 INPUT A$20 PRINT" ";A$Try these answers:HIHI, THEREHI: 1 2 3RULE: Do not put any commas or colons into the string you type in answer to thecomputer.If you accidentally do put one in, the computer may answer:9EXTRA IGNOREDand continue This means that the computer chopped off everything after the comma orcolon and then continued running the program.42
YOU WEAR TWO HATS, USER AND PROGRAMMERYou are a PROGRAMMER when you write a program. The person who runs theprogram is a USER.Of course, if you run your OWN program then YOU are the USER.When the programmer writes a PRINT command, she is speaking to the user by writingon the screen.When the programmer writes an INPUT command, she is asking the USER to saysomething to the computer.It is like a game of "MAY I?" The only time the user gets to say something is when theprogrammer allows it by writing an INPUT command in the program.Assignment 6:1. Write a program which asks for the user's name and then says something silly to theperson, by name.2. Write a program which asks the user to INPUT her favorite color and put it into a boxcalled C$. Now the program asks for her favorite animal and puts this into box C$,too. Have the program print C$. What will be printed? Run the program and see if youare right.43
