We will learn the math of Applescript.
Try this code:
set a to 5
set b to 6
set c to a + b
display dialog c
--should display 11
What it does here is sets the vars a & b to 5 & 6, respectively. It then sets the var c to a + b, or 5 + 6, which is 11. c is 11. It then displays c and comes up with 11.
You can do this with anything else. NOTE: The sign for multiplying is * (shift + 8), not x. Same goes for division. The sign for it is / (left to right shift).
The good thing is Applescript uses BODMAS (PEMDAS for others), and doesn't just go from left to right. I'll show you what I mean:
set a to 5 + 6 * 2
display dialog a
--should show 17. If it went left to right, it would show 22.
If that's not it:
When a is set to 17, It goes BODMAS (or PEDMAS!!!). No brackets, or whatever is next, no division, MULTIPLICATION! Boom! 6 * 2 is 12. Now it's left with 5 + 12. That's 17.
Here's left to right:
5 + 6 * 2
5 + 6 = 11
11 * 2 = 22
See?! They're different!
NOTE: Applescript is limited to math. Be careful!
END OF LESSON 2-1. In PART 2-2, we will have dialog boxes in dialogs. For now, bye!
