I'm wondering if I have a program that uses a variable, but isn't directly defined, and another program, that uses the same variable name and gives it a different value, will it set it for both programs?
When a program gives a variable a value, it sets that variables value for the entire calculator. So, if you have 2 programs that use the same variable(which you probably do), you need to set the value of the variable before the main game starts in each one of your programs. Note, you only need to preset the variables that you are going to use in the program. Hope this helps :)
