What's the differece between DATA(BIT,IDATA,...) and DS ?
The so-called "bible" doesn't tell you how to write programs in assembler, nor how to use any particular assembler.
Unfortunately for the OP (and others like him), everything on the Keil site seems to be focussed on 'C' - there is precious little on how to write programs in assembler...
Maybe check-out the Book list:

Yes: familiarity with the so-called "bible" is necessary, but not sufficient!
