I understand the concept, and that locations are referenced as the center of
a stack object. What I need to know is the actual syntax. When you get the
location of something, its returned as "200,300". How do you subtract 150
from the 300 part of that returned value?

Specific example: I want to set the palette's location on the left side of
the main stack, aligned at the top. I need to set the palette's location as
(-150,-120) relative to the main stack. So, I get the location of the main
stack; say its currently at "400,600". Now what's the actual syntax of the
set location command for the palette?
