Hello all, I have problems with the function wtworkproc. This is the situation: I want to do time consuming operations like reading large signal channels via the HDF-Interface in the background. So I use wtworkproc to initiate these operations, but it results in an error message: % Procedure/function called with too many parameters: READ_SIGNAL_BG. % WTMAINLOOP: Unable to manage a WorkProc. I did exactly as it's descriped in the manual. Does anybody have a working example with this function My program fragment: ----------------------------------- ... param = 0 wtid = wtworkproc("add",'read_signal_bg',param) .... PRO read_signal_bg, wid, bind , wtid ... status = wtworkproc("remove",wtid) END ------------------------------------ Thanks for help in advance Wilhelm +=========================================================== ================+ : : : : : Wilhelm Gr"uber : : : : +=========================================================== ================+ : : E-mail: grueber@informatik.uni-bonn.de : : : : : \\\!/// : Rheinische Friedrich-Wilhelms- : : / \ : Universit"at Bonn : : ( o o ) : Informatikinstitut Abt.
