Summary:

I came across some code I don't understand...help, anyone?

max( /min( usage

:max(1,min(8,A+(Ans=34)-(Ans=25->A

(from Pong)
I know this is a piecewise expression, but I didn't know you can use max( and min( in this way. Could someone explain how it works, syntax for all cases, etc.

max(num,num
or
max(list

min( is the same

Work from the end of the expression:

A+(Ans=34)-(Ans=25

Assuming Ans is the keypress and A is the position of the paddle, it first moves it.

min(8,A …

This makes sure that A is not out of bounds. If A is less than or equal to the maximum boundary, the calculator is left with A. If A is outside the boundaries, it takes the maximum boundary for A.

max(1, …

This does the same thing, comparing A to the lower boundary, and taking A if A is within the boundaries, and the minimum boundary if A is lower than it.
