    Defines: bfill()

    bfill(dst, len, fill) moves "len" fill characters to "dst".
    Thus to set a buffer to 80 spaces, do bfill(buff, 80, ' ').

    Note: the "b" routines are there to exploit certain VAX order codes,
    but the MOVC5 instruction will only move 65535 characters.   The asm
    code is presented for your interest and amusement.
