    It runs fine for me. What system are you running? I wonder if running strip.exe (a program to remove unnecessary information from the executable) had anything to do with it? I've included a the pre-stripped version here, just in case you want to try it out. Another option (though I'm not sure you're familiar with) is to build the program from the source with a C++ compiler.
    Code:
    #include <cmath>
#include <complex>
bool euler_flip(bool value)
{
    return std::pow
    (
        std::complex<float>(std::exp(1.0)), 
        std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1.0)
        *(1 << (value + 2)))
    ).real() < 0;
}

    When you load minibasic, or when you load a basic program into minibasic?

    If the latter, what program are you loading?

    I downloaded the zip-file onto my work-machine, and although I haven't got any basic file to load into it, it certainly works as far as getting a "Ready" prompt, and a 10 Print "Hello, World" works fine too.

    OK, good. Let us know if you find any bugs or have any problems with it.
    Code:
    #include <cmath>
#include <complex>
bool euler_flip(bool value)
{
    return std::pow
    (
        std::complex<float>(std::exp(1.0)), 
        std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1.0)
        *(1 << (value + 2)))
    ).real() < 0;
}

    I've just updated the code quite dramatically. I'm not sure at this point if I've broken something - running pitman in game-mode seems to work correctly.

    Alright. I'm tied up in a project at the moment, but as soon as I have a chance I'll check it out.
    Code:
    #include <cmath>
#include <complex>
bool euler_flip(bool value)
{
    return std::pow
    (
        std::complex<float>(std::exp(1.0)), 
        std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1.0)
        *(1 << (value + 2)))
    ).real() < 0;
}

    Good point.
    How's the port coming along?

    How exactly does a C/C++ programmer benefit?

    Debatable. I once had the task of translating a legacy program written in BASIC to C. The problem was that over the years, with each modification, the program had developed more and more bugs, and ran ever slower. The program consisted of at least 10,000 - 15,000 lines of code, and the maintainers openly admitted that they had problems understanding the code themselves (which they had written!), and were not at all sure what was causing all of the errors. After reading the code for a few hours it became clear to me that a complete rewrite would be necessary. Tracing the flow of the code was nearly impossible, and global variables were strewn all over the place. A real mess. Incidentally, the C version took only a few days to complete, was orders of magnitude smaller, and ran much faster. The bottom line is that BASIC just isn't very scaleable. It may be 'useful' for certain toy projects, but falls way short of being a 'real' programming language.
    True, but C++ is a good starting point.

    I was actually waiting to see if you had found any bugs or missing features. If not, I suppose we can make a final release out of it, but I just wanted to make sure that everything was working properly before doing that.
    Code:
    #include <cmath>
#include <complex>
bool euler_flip(bool value)
{
    return std::pow
    (
        std::complex<float>(std::exp(1.0)), 
        std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1.0)
        *(1 << (value + 2)))
    ).real() < 0;
}

    Is this the latest release?

    No, there have been some changes since the last release, so I'll try to post the newest one sometime near the end of the week (assigned with a 2.0 version number).
    Code:
    #include <cmath>
#include <complex>
bool euler_flip(bool value)
{
    return std::pow
    (
        std::complex<float>(std::exp(1.0)), 
        std::complex<float>(0, 1) 
        * std::complex<float>(std::atan(1.0)
        *(1 << (value + 2)))
    ).real() < 0;
}
