1. Command Line Continuation
I haven't noticed if EU has command line continuation or if you can wrap
a line onto another line. What are the rules to this?

I assume you are not talking about DOS command lines, but about Euphoria
program statements.
The only things that can't continue over multiple lines are text string
literals and commments. For example, below is a valid Euphoria statement...
if thisfld > 0 and
thatfld = 1
then
abc
=
"a very long string that is longer than " &
"a single line of text in the editor"
end
if

Erm, does this answer your question?
a="a very "&
"long "&
"string"
is the same as
a="a very long string"
or
myProcedure(lots,
and,
lots,
of,
parameters)
is the same as
myProcedure(lots,and,lots,of,parameters)
Eu does not care much about line breaks, except for long strings,
which as shown in the first example, & is required to join them.
In fact, I've indented it for show, you don't have to, but it is
easier to read like that.
One of the most stupid things I ever wasted my time on is the
following program, which should scare you somewhat, but I think it
proves a point 
-- goto.exw: usage exw goto.exw <file>
constant togo="goto" type
goto(integer
goto) return
goto=
goto end type type
goto_s(sequence
goto) return equal(
goto,
goto) end type
goto
goto_t,
goto_u procedure
goto_a(
goto
goto)
goto_t+=
goto if
goto then
goto_u=
goto end if end procedure procedure
goto_b(
goto
goto)
goto_u=
goto_u*
goto+1
goto_a(
goto_u=
goto*5) end procedure function
goto_c(
goto
goto)
goto_b(
goto=togo[
goto_u]) return
goto!=-1 end function procedure
goto_d(
goto
goto)
goto_u=
goto!=1
goto_t=
goto=0 while
goto_c(getc(
goto)) do end while close(
goto) printf(1,"%d goto \'s\n",
goto_t) end procedure procedure
goto_x(
goto_s
goto)
goto_d(open(
goto[length(
goto)],"r")) end procedure
goto_x(command_line())

Correct assumption, sorry I wasn't clear. Thanks much for the answer
it will be a big help since some of the code I am porting is already
resulting in longer lines than the editor I'm using.

I think, Rob needs a separate section in his Archive
to keep such the jokes.
Submit it to Rob!
Good Luck!
