Euphoria does not have structures like C.
Euphoria has atoms and sequences (only).
The size of data in Euphoria is largely irrelevant since
Euphoria is a high level language and does not define
the way that atoms and sequences are laid out in memory.
You can't get the address of a Euphoria variable.
Euphoria programs can call C functions via
the Euphoria routines c_func() and c_proc().
Euphoria can access memory using peek() and poke()
and can allocate memory using allocate(). To access
fields in a C structure you must get a pointer (address)
to the structure, and then use peek() and poke(), or peek4u(),
peek4s(), or poke4() to read/write the fields. You need to
calculate the offsets of the fields you are interested in.
Most fields are 4 bytes in size. Sometimes a structure
will contain a gap so the next field will be better aligned.
See one of the WIN32 example programs on the RDS Web site.
Also read DOC\PLATFORM.DOC in the Euphoria .ZIP file.

When you hit the Reply button to reply to a message
from the list server, you need to check whether your
reply is going to "Euphoria Programming for MS-DOS"
or only to the person who posted. It seems to vary
depending on who posted the message. I guess it
has something to do with the "Reply-To" information
they specified. You should add the EUPHORIA mailing
list address to your address book.
