in reply to dynamic loading modules

The symbol GetOSName is not defined at compile time, so move the conditional module loading into a BEGIN block.

    thx.. I added this to my begin block
    if ($^O eq "MSWin32") { print ("begin\n"); my $win32 ="Win32.pm"; require $win32; import $win32 qw(GetOSName); }
    I get the print message fom my begin block code. and still call it
    my $os = GetOSName();
    and it still fails
    Undefined subroutine &main::GetOSName

      This is never going to work:

      my $win32 ="Win32.pm"; import $win32 qw(GetOSName);

      If there isn't already an import() in your current package, this will effectively become:

      'Win32.pm'->import( 'GetOSName' );

      Because there's no package called Win32.pm, nothing will get imported. You're better off writing:

      Win32->import( 'GetOSName' );

      ... or even:

      'Win32'->import( 'GetOSName' );
      The line calling GetOSName() should never be called on any system other than Windows. Fix the logic of your program.
