  • What kind of Dos is the best ?

    Hello,

    I´m using MS-Dos 6.22. It works not with PII PIII computers very
    well. My Progs are big over 300kb to execute.

    Is Dr.Dos 7.01 or FreeDos much better ?

    Thanks for ideas and responses ?

    Regards

    Matthias Kuhn

    You could try to use Dos 7/Win98:

      DOS 7 is excellent, it is possible to get 620+ KB of free RAM with
      careful attention to HIMEM.SYS and EMM386.EXE, plus getting the drivers
      and stuff loaded high.

          Hello,

          thanks Georg and David.

          Michael I agree with You and I´m programming in PB8.01 Win too.

          But it needs so many time to translate the old Pb3.5dos Programms
          to working PB 8.01 code. Plenty changes in commands e.g. INCR a%,10
          open had an new syntax - the old is not supported
          - don´t work any more.

          And to use a bit of the new opportiunities takes much time more.

          The next is that is difficult to get working old computers like
          an 486DX. And MS-Dos 6.22 is not realy made for an PIII or higher
          processor.

          Any suggestions to make the job quicker :< ???

          Best Regards

          Matthias Kuhn

            VMWare? I know one or two who reckon it's magic.

            As for old computers, P800s and above are now to easy to find in skips,
            I get problems with them building up in heaps, and I find it really hard
            to chuck them out!

            I've got a beautiful dual 486/33 Compaq server with 8x500MB RAID drives
            giving a humongous 3GB. Beautiful thing, cost a fortune. Doesent even
            make a decent coffee table.......

                yesterday I found out about WDOSX DOS extender, quite impressive.

                  I used DR-DOS (7.03) a lot with PB/DOS programs and it always worked perfectly.

                      PC DOS 6.3 may be a good find too. They were MS-DOS's major competitor
                      and had many improvements over them except two...long file names
                      and Windows, so they faded away.

                        I don't know why does this make you sad. However, believe it. Not only there are still applications where DOS is the best choice, there still will be for long.

                          Still?

                          Hummmm. Even though I programmed in DOS for over a decade, I can't say that I ever found it to be the best choice.

                                I've got DR Dos running on a fat32 drive. I think it is the only
                                one that will. I only use it to run old pb code though.

                                  FreeDOS (http://www.freedos.org) can also handle fat32 drives.

                                    Then you never wrote programs for industrial automation, or number crunching, or apps that have to run unattended, and these are only examples i directly know of .
                                    BTW, why were you using it in fields where it wasn't the best choice ?
                                    For a long time MS-DOS was the best choice because it was the only choice.
                                    But i obviously wasn't referring to that, otherwise i wouldn't have called it a "choice".

                                      I think that, if you compare "Number Cruching" applications carefully, you'll find that PowerBASIC Windows Compilers easily outperform DOS applications. Check it out...

                                        No Bob, i'll just trust you. While my personal experience would suggest otherwise, i realize that i made a wrong statement (about number crunching).

                                        The mentioned situation was this: a financial advisor company which had number-crunching Windows apps (Windows 98); i don't know the language these apps were written in, however they were compiled, not TradeStation scripts or such. The apps were trading systems and were crunching some tenths of MB of numeric data in one time. They were taking forever in doing the job.

                                        I set them up one of those boxes with just DR-DOS and a PB/DOS 3.5 program implementing the very same trading systems and reading the same data. This app used EMS (PB/DOS VIRTUAL arrays).

                                        The PB/DOS app took at least 5 times less to do the same job. It's possible that those Windows apps were compiled with a slow compiler (it certainly wasn't PB) and it's possible that they weren't as well written as mine (of course ) was , however i just do know that one of the reasons was that my implementation allowed the app to use all the 32 MB of EMS for the job, while the other apps were swapping memory to disk for sure because much memory was used by Windows for its own things.

                                        However i realize that i gave too much importance to that observation and this led me to a wrong conclusion.

                                        ------------------
