You can poke in any memory that is owned by your program.
When you used GlobalAlloc() you requested that the OS
assign some memory to your program therefore you can
poke in that allocated memory. The only thing I think
that you will need to be careful of is to release that
memory with the proper OS function because I don't think
Euphoria will do that for you. Euphoria manages it own memory
off the heap memory and releases it when Euphoria ends.
