HuwG BS: Another question for Brits (117* d) RE: BS: Another question for Brits 16 Feb 08

" ...we all learnt multiplication tables up to 12 times. Don't kids still learn their tables?

Working in IT in the 1980's, it was sometimes necessary to do lots of calculations in hexadecimal i.e. using base 16. In this system, A is 10, B is eleven and so on up to F which is 15. OK, so how many channels can you have given that they have a minimum buffer size of 0x0100 and the available buffer space using redundant initialisation functions in the combined code and data segment is 0xFAB0 - 0xE810 ? (I have made things easy for you by using the ALIGN = PARA directive so that all function and segment addresses are multiples of 16.)

This was all in the days before Windows with on-screen calculators. It was almost all done on scrap paper, although there were one or two programmers who could do the sixteen times table in their heads.
