I am sorry for my three times of posting the same question! It is the first
time for me to post question here, so I don't know some rules! Sorry!It is the define of RVECENT whiche has two arguments f and n, but only f is used in the code, n is not used.
I want to know the function of the argument n, since it is not used in the code.
Thank you very much!
#defineRVECENT(f,n)\
b f; nop
You answered your own question, it has no function.
Assuming each jump vector is x words long, it could be used to generate an address to locate the code in the case where you didn't want to explicitly fill each jump vector.
