    EQU substitution??

    I think in assembly EQU pulls the trick but in C,

    how do you equate on variable to another so that everytime the compiler sees a word it substitutes the other word into it...


    DIN EQU RC0;

    DIN = 1;
    DIN = 0;
    DIN = !DIN;

    *I want complier to substitue RC0 in for DIN...thanks

    DIN EQU RC0;
    #define DIN RC0
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
