parse long string message from HC05 and serial comm with delimiter

I am trying to find some example of how to recieve 200 character long message with comma delimiter (ex: int, long string, long string, int, int) and then i break them down to take some actions. can someone help me with that since arduino programming is so annoying due to limited memo. i would appreciate any help thanks.

How would you do it using unlimited memory? Something like this?
serial input basics

you can use strtok() to extract the substrings delimited by commas

void
separate  (
    char *buf )
{
    char *s;
    char *t;

    for (s = buf; t = strtok (s, ","); s = NULL)  {
        printf ("  %s\n", t);
    }
}
