| I would like to run an old DOS app but also be able to access commands to copy/delete files without stopping the application. Is OS/2 for me? Thanks Software Monkey |

| Hi SMonkey, DOS apps actually behave better on OS/2 than most applications, including MS-DOS (PC-DOS, etc.). OS/2 was initially marketed as a "better DOS than DOS". Unforutnately most people were moving towards MS Windows and the rest is history. Your questions: 1. Is OS/2 for me? 2. Is it possible to run DOS applications in OS/2? 3. Do I need to recompile the software? 4. Are there any issues that may cause a DOS app not to work in OS/2? |

As it has been alerady stated, the DOS in OS/2 is better than DOS spread by that guy from Redmont Here is some (perhaps) useful info about the DOS box in OS/2:1. It's DOS 5. 2. What will NOT run in the DOS box: 3. Crash of DOS box (and also WIN-OS/2) under eCS with some video cards. |

Thanks for the info. This is the sort of stuff I need to know if it collapses in a heap although I am hoping it will all go smoothly ![]() I do have the source code for the application so I can mod it if any of the points you have raised prove troublesome. |

| Make sure you get the virtual device drivers by Martin Kiewitz. They improve the accuracy of the DOS box a lot. One can even correct apps that have been compiled with certain buggy compilers on the fly. Get the stuff here: |

| Another thing to mention (regarding the "beter DOS than DOS") is that DOS programs under OS/2 can sometime perform a lot better because OS/2 can "inject" some limited multithreading in the DOS app. How does this happens? It's simple: since any disk IO operation is in reality performed by OS/2, it executes the IO operation in another thread and returns control to the DOS app immediately. This is not always desireable, so it is toggled by a DOS VM configuration option: INT_DURING_IO. That is: the app can receive (and thus service) interrupts before an IO operation is finished. Hope this helps. Cris |
