Ack. I remember when I graduated from Basic to C, I was so pissed off
because there was no mid$/left$/right$ and so forth. until i discovered
The Joy of Pointers (tm)  :)

char *mystring="1234567890";
char *mid3;

to get characters 5..7 (destructively though)
mystring[7] = '\0';  /* chop off 8th character and rest */
mid3 = mystring + 5; /* point to fifth character */

and you're there!!
