Hi everybody,

I have a UDF that includes two define a macro, for example, two define source. I want to use the output of the first macro in the second.
What should I do?
I know that you can call one function in the C programming language, but in that case, you should define the function prototype first and other things.

So I want to use the output of first in second; what should I do?
Thanks

The output of the macro is... well, not something you can use directly. You have (for example) defined source A in a complicated way, and want to say that source B should be twice source A. There is no direct way to do that, or at least no simple way. Options are:

1. Just define two sources, put the code in twice.
2. Make a (classic) c-function, and let both macro's go that function.
3. Use a UDM to store the source from A, and read that UDM in B.

All can work. What is best, depends on the specific problem, and on your programming skills.

Well, thanks for your attention.
I think the first option is the best for me.
