B, I remember it well and with fondness.  I was one of the folks who was 
involved in hacking on AberMUD (and its predecessor BBS HoneyBoard) in B at 
the University of Wales, Aberystwyth on their Honeywell L66 back in 87/88..

It had both the variable types you could ever need, namely auto and extern.

FYI.. (from the Users' Reference to B via Wikipedia):

/* The following function will print a non-negative number, n, to
  the base b, where 2<=b<=10,  This routine uses the fact that
  in the ASCII character set, the digits 0 to 9 have sequential
  code values.  */

printn(n,b) {
        extrn putchar;
        auto a;

        if(a=n/b) /* assignment, not test for equality */
                printn(a, b); /* recursive */
        putchar(n%b + '0');
}

Takes me right back..
