I have attached a file that I just created that has 2 functions with  it and the Main calls both and then calls one that does not exist.  If  you add an error pin on the call a message will generate with the status of  the a problem in the function if there is a problem like the function does not  exist in the first place.  Something like this might be able to be used  in a setup routine to check status with some IF statememts comparing to the  flag 517 (I think). The Only problem with my ides is that I don't know if  this can be used with functions that have some guts to them.  If the  function does exist, it might try make something happen that you do  not want.</P></DIV>  <P>anyway, the error pin is my attempt to a solution</P>  <DIV></DIV>  <P>good luck</P>  <DIV></DIV><BR><BR><BR>------------------------------------------------  <DIV></DIV>  <DIV></DIV>Michael Ruff  <DIV></DIV>  <DIV></DIV>Project Engineer Mgr.  <DIV></DIV>  <DIV></DIV>  <DIV></DIV>  <DIV></DIV>Challenge Environmental Systems  <DIV></DIV>  <DIV></DIV>700 Research Ctr.
