GlobalAlloc(Integer Flags dWord Bytes)
The GlobalAlloc function allocates the specified number of bytes from the
heap. The 'Flags' parameter specifies how to allocate memory. If zero is
specified, the default is GMEM_FIXED. Except for the incompatible
combinations that are specifically noted, any combination of the following
flags can be used. To indicate whether the function allocates fixed or
movable memory, specify one of the first four flags.
