- Variables can change throughout the program’s execution
Constant
Similar to a variable but cannot be changed within the program once it is defined
Loop

For loop
Used when the number of times to repeat a block of code is known
While loop

Do loop
Used when an indefinite iteration needs to happen; will only stop until some condition is met at the end of the loop

Because of all the log files/temporary files created as part of the scripting process
What can be lost due to faulty loops?
