+/* File : bfill.c
+ Author : Richard A. O'Keefe.
+ Michael Widenius; ifdef MC68000
+ Updated: 23 April 1984
+ 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.
