Boy I had to say this but...on page 137 of the manual it states:

The Mode names (e.g. T2400) are defined in the file MODEDEFS.BAS. To use them, add the line:

Include "modedefs.bas"

to the top of the PICBASIC PRO™ program.

Use your manual, its the Bible of PICBasic. I use mine so much that its falling apart. I also have the web version bookmarked.
