1. A question to Robert Craig
Hello Robert,
it seems that the loading order of the include files is essential ??
Is that right ?? How to avoid this ??
Thanks Karlheinz =

I think you can include any of the standard .e files
in euphoria\include in any order. Other people
may have written include files that assume that another
include file will already be present.
The global symbols of the include file will be defined at the
point where you place the include statement, so you should
include the file before you try to access the global symbols.
(Non-global symbols are not "visible", except in the include
file itself.)
One handy thing about Euphoria includes, that
is not true for C/C++ and some other languages,
is that Euphoria will ignore subsequent attempts
to re-include a file that has already been included. (In
C/C++ you will be flooded with messages about
multiply-declared symbols etc., so you have to set up
an awkward "ifdef" mechanism to avoid this situation.)
In Euphoria, if your include file needs another
one, feel free to add an include statement for it, e.g.
first.e:
include second.e
....
....
main.ex:
include second.e
include first.e
Although main.ex already includes second.e, the
"include second.e" inside first.e won't hurt, and will allow
first.e to work, even if main.ex doesn't include second.e.
