yes, there is a ticket open on that exact issue,
#1886

As I said there are a few minor parser issues, and it's good time to figure out if there are others.

OK, cool. This is the only parser issue I've seen. When I add the continuation char (three places in my code), it runs.

Some thoughts.....

Looking at Engine/csound_orc.lex in cs6 the lexing of '+' is

"+"{OPTWHITE}"\n"? {
                      if (UNLIKELY(strchr(yytext, '\n')))

csound_orcset_lineno(1+csound_orcget_lineno(yyscanner),
                                             yyscanner);
                      return '+';
                    }

So the whte space after the plus is removed. So Dave's Code becomes 
  aout = (adiff  * $CTL_COMBOS_DIFF1) + (adiff2 * $CTL_COMBOS_DIFF2) +



And so e dse what we get in cs6

.  Compare this with the Engine.csound_orc.lex in cs7

I cannot find the selfsame ode nor a version.  cs6 uses more Flex formats 
but I think it is lost.

Who wrote the cs7 lexer?  Was not me and  do not follow it.

On the other hand mu Head is hurting so thinking is hard

Steven wrote it. Can we add that whitespace removal to it and see if it does the trick?
