Editing Expression Components and Instructions (section)

=== Ternary Functions ===
 h [function]
The '''h''' instruction gets three values from the stack, applies the function provided, then pushes the result. The function used can be:
{| class="wikitable"
|+
| cond
|Returns second value if first is non-zero, otherwise third value is returned 
|-
| rand
|Unimplemented, acts as cond
|}

For example:
 = 6 n 2 n 1 n 0 h cond
would set the X scale of the bone to 2 (since the third value is 2 and the first value is 0)
