The Prompt command functions much like the Input command. It allows you to type a value to be stored to a variable. You can also prompt multiple values at the same time. For example:
Prompt A
//This will ask the user to type a value for A
Prompt A,B,C
//This will ask for a value for variables A,B, and C
You can also ask for input in user-made variables
Prompt cool
//This asks for a value for the variable "cool"
