Show function, variable

Hi!

It is my first post here, so don't tread on me :)! I want to ask, how to watch result of function?

I don't know what to do with this - I tried "Watch 1", but I can't get satisfied result - I mean see "EQUAL" or "DIFFERENT".

I attached my code here:

#include <LPC21xx.H>
#include <string.h>

#define NULL 0

enum CompResult{DIFFERENT, EQUAL};

enum CompResult eCompareString(char pcStr1[], char pcStr2[]){

        unsigned char ucCounter;

        for(ucCounter=0; pcStr1[ucCounter]==pcStr2[ucCounter]; ucCounter++){
                if(pcStr1[ucCounter]==NULL){
                        return EQUAL;
                }
        }
        return DIFFERENT;
}

int main(){

        char pcStr1[] = {'a','b','c', NULL};
        char pcStr2[] = {'d','e','f', NULL};
        enum CompResult{DIFFERENT, EQUAL};

        eCompareString(pcStr1, pcStr2);

        return 0;
}

Thank's for help and have a good night ;)!
