thanku Dizzutch, tempest, Machiavelli, and all those who passed by.
i am sorrrrrrry for the misunderstanding. but i am REALLY NEW. & feel bad about my unconsciousness. in fact i use command prompt (DEBUG) to write the code, till now we have not met any of the assemblers i saw many talk about in the internet, like MASM, RASM etc.. if i am not wrong.
again thanks alot. & sorry for not mentioning this in the beginning.
& tempest i dont get the code u wrote, :o sorry
here is the code i felt will work but am not sure coz i don't know how to test
MOV BX,0 ; THIS IS THE B=0
MOV CX,10 ; THIS IS THE COUNTER a=15
MOV AX,A ; AX=C = 10
MOV DX,64 ; D=100
ONE :CMP CX,0
DEC CX
JGE LP
LP: ADD BX,AX
CMP BX,DX
JL ONE
JGE LP
HLT any body know what i am talking about, if u dont mind check. & tell me whats wrong or what should be corrected?
