SOURCE CODE FILES

The program is written in Turbo Pascal, version 2.0 for CP/M and
3.0 for MS/PC-DOS.  Version 3.0 does not use BCD reals or the
8087 support.  The program uses the Turbo Access routines found
in the Turbo Database Toolbox.  Most of the procedures are
overlayed, so the object code is in two files, MAIL.COM, the
root, and MAIL.000, the overlay file.

The program source code is contained in the following files:

     MAIL.PAS			The main program
     ACCESS.BOX, GETKEY.BOX,	Turbo Access routines -- not
     ADDKEY.BOX, DELKEY.BOX	included with the program --
				you must buy them from Borland
				International
     IO20.INC			Formatted input/output routines
     MAILDATE.INC		Reading and writing dates
     MAILGLOB.INC		Global declarations
     MROOT1.INC, MROOT2.INC	Miscellaneous routines that are
				called by more than one procedure
     MINIT.INC			Routines to initialize the
				program when it is first started     
     MSETUP.INC			The Set-Up menu
     MADDETC.INC		Add, change, delete a name and
				record contributions
     MPRINT.INC			Print list of names and labels
     MAILMERG.INC		Create mailmerge file

TO COMPILE FOR CP/M

In file IO20.INC, comment out the version of procedure KEYIN that
is for MS/PC-DOS and un-comment the version that is for CP/M,
specifically the Kaypro.  In file MINIT.INC, make sure that the
two calls to the BDOS procedure are NOT commented out.  These are
the only places the source code differs between CP/M and
MS/PC-DOS.  This is one of the many reasons I like Turbo Pascal
so much -- the code is very portable.

Compile to a COM file with the End address set to $D440.  This
leaves plenty of room for different size operating systems.

TO COMPILE FOR MS/PC-DOS

In file IO20.INC, comment out the version of procedure KEYIN that
is for CP/M and un-comment the version that is for MS/PC-DOS.  In
file MINIT.INC, make sure that the two calls to the BDOS
procedure are commented out (they are plainly marked).  These are
the only places the source code differs between CP/M and
MS/PC-DOS.

You probably do not have to overlay the program for MS/PC-DOS,
although I have done so just to ensure source code portability. 
The overlay procedures are in files MINIT.INC, MSETUP.INC,
MADDETC.INC, MPRINT.INC, and MAILMERG.INC.  Search for the
keyword "overlay" and delete it before compiling.
