UDO without arguments

Hi everyone,
I have a question about UDO’s. I’m working on a project with a lot of global variables.
These global array’s act as a database and are crucial in deciding in what the next sequence will be to be played. In order to make the necessary calculations I work with dedicated UDO’s. My problem is that the whole data system is built around global array’s and so my UDO’s don’t need extra arguments. Running those UDO’s result in error massages that CSound expected arguments. I can rewrite them, give them fake arguments and run them without using the arguments, but that’s quite unelegant.
Is there a way to use ‘void’ functions, or do I have to work around that.

Thank You, Leo

Sorry for the annoyance, but I can answer my own question. It is all in Floss Manual, but I missed it several times… Just add 0, 0 as arguments and you have a ‘void’ opcode.

yes, and perhaps to add that you can define a UDO at any position of
your code.
so if you use a global variable in the UDO you can initialize it first,
and then put the UDO definition afterwards.
