Hi, Some examples in CsoundQt broke because of the new limitation in function syntax, where spaces are not allowed between the function name and the parenthesis. It would be great if spaces were allowed, as it seems to me this is actually a change that breaks backward compatibility with older orcs. It's not a big problem now when we are all aware of the change but it might be a time waster some years from today when someone tries to recycle old code...Cheers, Andrés |

The problem is ambiguity aaa bbb (ccc) is that opcode aaa with argument bbbb(ccc), or is it opcode bbb delivering aaa from ccc It is Rory's reported problem. The space after a function was OK as there were a liited number of functions, but now everything is/could be a function. The only way I know to fix it like to suggest will also remove the "functional" syntac form. We coud have two parsers..... > Hi, > > Some examples in CsoundQt broke because of the new limitation in function > syntax, where spaces are not allowed between the function name and the > parenthesis.

Thanks for the explanation. I also see no way around it. Maybe the error message can give some information. How about if the unexpected character is '(' mention that there can be no space for functions? Cheers, Andrés On Sat, Aug 3, 2013 at 12:40 PM, <jpff@cs.bath.ac.uk> wrote: The problem is ambiguity |

| Could we just not allow (var) as an opcode argument? If not allowing that fixes the function space parenthesis issue, then it's a toss up between the two. Victor On 3 Aug 2013, at 20:53, Andres Cabrera wrote:
