I'm not sure what you are confused about. The API defines a series of values
and functions which you can use in your NQC programs. The three lines above
show three such items. You can use MSTimer(n) where n is 0 through 3 much like
how you can use Timer(n) or FastTimer(n). The built-in API simply makes these
functions available to you without requiring you to write low level NQC code.

What brick type do you have selected? The status bar at the bottom of the main
BricxCC window should say Swan if you picked Swan at the Searching for the Brick
dialog. If you picked Swan and it says Swan on the status bar then you do not
have a recent copy of the swan_test.zip file. One of the first copies of NQC
with support for the Swan firmware had a bug in the built-in firmware which made
it so that a few API functions were not correctly defined when the Swan firmware
type was selected. You should, in this case, download the current version of
swan_test.zip off my BricxCC website
(http://bricxcc.sourceforge.net/swan_test.zip). I'm working on a new official
release that should be out this month, with any luck.
