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())
