4DOS 7.50.2 
(Note: .2 to denote modification from initial source release to allow building,
 where 7.50 is initial freeware release & 7.50.1 is initial source release.)

To build 4DOS 7.50:
 - apply 4dos7502.diff
 - create DOS subdirectory, e.g.
       C:\4DOS\SOURCE\>  MKDIR DOS
 - copy SASJP.LIB to DOS subdirectory, e.g.
       C:\4DOS\SOURCE\>  COPY SASJP.LIB DOS
 - setup MSC 7 (or higher) and MASM 6.x environment variables, e.g.
       C:\4DOS\SOURCE\>  \C700\BIN\NEW-VARS.BAT
       C:\4DOS\SOURCE\>  \MASM611\BINR\NEW-VARS.BAT
 - run make specifying 4DOS makefile, e.g.
       C:\4DOS\SOURCE\>  nmake -f 4DOS
 - finally, test your new 4DOS executable, e.g.
       C:\4DOS\SOURCE\>  DOS\4DOS.COM


Notes:
  Currently build still requires SASJP.LIB from initial source library.
  The registration functions (shareware/registered/serial#) are not
  included and the calls to them are #ifdef'd out so never called.
  Although it builds now, there are still plenty of warnings (at least
  with my MSC compiler & MASM versions) and no help text.
  It is only minimally tested, so there may be other serious errors still.
