LOL, we've done all the work for you!

All you need to do is copy all those capitalised words above,
from my post and the other, into a single plain text file (such
as created by Notepad).
Then, save that file somewhere, and then open PureBasic,
open the Preferences, open the "Editor" section, open the
"Coloring" item, click the "Custom keywords" bit, then
browse to the saved text file and apply the setting.
It's easy! See below.
