When I test the value of qq on return, with the debugger, qq appears to be empty.  If I put add msgbox "the value of qq is \r"<qq<"\r", the message box shows qq as 9.  Even though qq is set to 3 digits, <F> qq shows as |                                                                           |. I have a dummy field q(1,.0)=""{qq and that field will show a 9 and test as 9.

Everything above points to qq not being (3,.0).

In the debugger, what do these (E)xpressions say?

     fieldlen(-,"qq")
     fieldedit(-,"qq")
