Hi Rob
I hooked the udf without any error message except the one.
But it is not working.Because , when Thread*tf=DT_THREAD(dt); is not implemented.
begin_f_loop(f,tf) command is not working. I guess ,the cause is that "tf" not defined.
I have put a Message line in UDF and it shows that time stepping is ok .But when I put it into begin_f_loop no message apperars on the screen.
I am desperately needing your help.
Regards
Teoman
