F_C0_THREAD vs. THREAD_T0

Victor

Hello!

What is the difference between the UDF macros F_C0_THREAD(f,t) and THREAD_T0(t)? They seem to give the same information but the former seem to be much more common to use than the latter (The UDF manual does not give one example with THREAD_TO but plenty with F_C0_THREAD).

Another thing: When I try to use F_C0_THREAD I get the following error message: t0=F_C0_THREAD(f,t); error message: THREAD_STORE:undeclared variable.

Does anybody know why this is happening? I'm using an interpreted UDF if that is of any help.
