How to deal with large numbers in Squiffy?

Question

The follow code did not work.

function addPoints(addNum,addOn) {
    if (addOn = selfHP)
        return selfLus + addNum
    else: 
        return null 

I am trying to use some outside of @dec selfHP five times. I tried to create a function however nothing at all happened. Do anyone know how to make something like this work?

Comments

This question is unclear. What are you trying to do?

---

Instead of having to do.

@inc someVar
@inc someVar
@inc someVar

To increase someVar by three, I am looking for a way that will take one line of code. Imagine if I was trying to do this in javascript.
var someVar =+3

Answer 1

Use this JavaScript to increase an attribute called "valiue" by 10:

set ("value", get("value") + 10);
