keil uvisioin 3 assembley programming

Please i would like to find out which header file to use when performing assembley programming on keil uvision3...
i am currently trying to download a program to opearare a lcd on the keil mcb900...

i am confused on which .inc file to add to my assembley program.

there is no need to add .inc files..
because when you program you select the controller for which you are going to write the code.. so keil take care of the registers etc. no separate inclusion needed.

i think that is the problem that i am having with the lcd....because i cant understand why it is not working..
and how do i select the controller...

when you create a new project it ask you to select vendor and controller to work on..
check the keil tutorial in tutorial section.
