   The assemblers and linker have been successfully compiled us-
ing  the  DECUS C  (PDP-11)  compiler  (patch  level   9)   with
RT-11/TSX+,  GCC  2.7.2 with Linux, Symantec C/C++ V6.1/V7.2 and
DJGPP (GCC 2.8.2) with MS-DOS and Windows 3.x/95/98.  

   The  device  specific  header  file  (i.e.  m6800.h, m6801.h,
etc.) contains the DECUS C 'BUILD' directives for  generating  a
command  file to compile, assemble, and link the necessary files
to prepare an executable image for a  particular  assembler.

   The required option, definition, and .mak files for building
the assemblers with the Symantec C/C++ V6.1/V7.2 Compilers are
included in the \asxmak\symantec\build directory.

   The makefile for Linux and DJGPP are in the /asxmak/linux/build
and \asxmak\djgpp\build directories respectively.

-... Building an Assembler

   The  building  of  a typical assembler (6809 for example) re-
quires the following files:  

     1.  m6809.h 
     2.  m09ext.c 
     3.  m09mch.c 
     4.  m09adr.c 
     5.  m09pst.c 
     6.  asxxxx.h 
     7.  asmain.c 
     8.  aslex.c 
     9.  assym.c 
    10.  assubr.c 
    11.  asexpr.c 
    12.  asdata.c 
    13.  aslist.c 
    14.  asout.c 


   The  first  five  files are the 6809 processor dependent sec-
tions which contain the following:  

     1.  m6809.h -  header  file containing the machine specific
         definitions of constants,  variables,  structures,  and
         types 

     2.  m09ext -  device  description, byte order, and file ex-
         tension information 

     3.  m09pst -  a  table of the assembler general directives,
         special device directives, and assembler mnemonics with
         associated operation codes 

     4.  m09mch / m09adr -  machine specific code for processing
         the device mnemonics,  addressing  modes,  and  special
         directives 


   The  remaining nine files provide the device independent sec-
tions which handle the  details  of  file  input/output,  symbol
table  generation,  program/data areas, expression analysis, and
assembler directive processing.

-... Building ASlink

   The building of the linker requires the following files:  

     1.  aslink.h 
     2.  lkmain.c 
     3.  lklex.c 
     4.  lkarea.c 
     5.  lkhead.c 
     6.  lksym.c 
     7.  lkeval.c 
     8.  lkdata.c 
     9.  lklist.c 
    10.  lkrloc.c 
    11.  lklibr.c 
    12.  lks19.c 
    13.  lkihx.c
