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.
