Hai,
Tnx for ur help, but i gone through the sample examples in the compiler i.e,(u Vision Help) and the sample programs!!! but i need nw is the linking of the c and asm in same file,
and can u tell me hw to start the asm program i.e start up... that is (_asm or asm) before starting the program? if u hav some more sample programs other than in compiler plz forward that to me.. so tat i can learn quick,.. friend!!!!

No. the old one is ending. Journal submission is just around the
corner here in India. And NXP or some smart sales guy must be dishing
