Help with Debug Command

Hello All

i am just trying to use the Debug command for the first time as i alway use the Hserout but
i need to save those pins for something else so i decided to use the Debug command on Port B.0
but when i try to compile my program i get the following errors
Attachment 6315

MPASM is case sensitive.
Use uppercase in your defines.

Thanks DT
