NAME:   BIGLIB.REL
DATE:   JULY 21, 1984

     This library module contains four subroutines which are further
described in Z80 Assembly Language Subroutines, by Leventhal & Saville,
Osborne/McGraw-Hill.  These routines are for doing String manipulation.
They are:

NAME                     PURPOSE

MFILL     Fills an area in memory with a character.

MUL16     16 bit multiplication.

SDIV16    Signed 16 bit division

UDIV16    Unsigned 16 bit division

CMP16     16 bit comparison

BFE       Bit field extraction

BFI       bit field insertion

MPASR     multiple precision arithmetic shift right

MPLSL     multiple precision logical shift left

MPLSR     multiple precision logical shift right

MPRR      multiple precision rotate right

MPRL      multiple precision rotate left

ASUM8     8 bit array summation

ASUM16    16 bit array summation

MAXELM    find the maximum byte length element in an array

MINELM    find the minimum byte length element in an array

BINSCH    binary search of a sorted array

QSORT     quick sort of a 16 bit array

JTAB      jump table..this routine expects to find LENSUB
          and JMPTAB defined as public in the calling program.

     These routines are set up for use with the Microsoft assembler and
linking loader.  To call them in a program you must reference the name
as an external and then simply do a call to the subroutine.  For
example,...

     EXT  BN2HEX
       *
       *
       *
       *
     CALL BN2HEX
       *
       *
     ETCETERA

     To use them with the loader, go:

* MPDLIB,YOURPROGRAM,/G
     (Or whichever command line toggle you like)

     All of these routines have been tested and debugged.  I am making
them available because they aren't available on a disk as far as I know.
To use this stuff you are going to have to buy the man's book.  If you
use these programs commercially then shame on you.  These are for
intellectual exercise only

     In order to use these subroutines it is to your advantage to sit
down and code a routine to test run them that you may really grok them
in full.  I suggest that you hunt down a copy of ZPMMAC.MAC which is a
library of Z80 macros adapted from "Mastering CP/M" by Alan Miller.
These macros or similar ones will alllow you to do console I/O on any
standard CP/M system... among other things.  Rather than upload all the
subroutines in one gross big file, I am uploading several smaller files.
So far these are:
