Describe the purpose of a local variable.

• A local variable only exists within the module it was created in. It is used to temporarily store data for the module.

• A local variable can be accessed by other modules easily to allow the sharing of information between modules.

• A local variable allows data to be shared within the local program file and not to other programs.

• A local variable can only exist in a procedure module as procedures do not return any value.

Describe the purpose of a global variable.

• A global variable is created in the main program (outside any modules) and is accessible through the program in any module.

• A global variable is created within a module to allow information to be shared globally with other modules.

• A global variable is used to share information to other programs in the same folder as the original program.

• A global variable is used to store information temporarily in a module and cannot be accessed by any other module.
