Can you be a little specific? Those codes show calculations. What exactly you want to ask?

 

[L's]

the question is

its on my paper that ive got from teacher..and it asks in exact words:

carefully examine both sections of code below and outline the major difference and similarities in regard to how the variable USER_ID is treated?

Well, I think the 1st code portion is declare the user_id as global variable within the form, and can be refer by any method within the form.

The 2nd code is to declare the user_id as local variable and the variable will be destroy once the method or the block within the declaration finish.

I hope I guess it right.

Cheers.
