The following software is used:

  - Windows XP (with SP2)
  - Digital Mars D Compiler version v1.010

After running "dmd.exe" with "test.d" as the parameter the following errors are displayed:

    test.d(1): module sdio cannot read file 'std\sdio.d

Upon doing some searching I stumbled on "sdio.d" file in "C:\dmd\src\phobos\std". Any ideas on how to get dmd to find sdio.d? Do note that I have successfully compiled a test program without the following lines of code which cause this problem:

    import std.sdio;
    writef("Hello World!");

Thanks, it is fully working now. I must have been very sleepy :).
