System()

Program systems out form one file to add a record in another file.  I need to know if the user breaks out of the record before completing it.
Sy=is the command line to run

Qq(3,.0)=system(sy) 

When the record being added is cancelled by pressing the <Home> key, exit "9" is executed.  On return qq should equal 9.  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.

My questions:
	1. Why does qq appear to be empty when dis-played in the debugger using <F> qq?
	2. Why does the actual value appear when displayed with a msgbox?
	3. If qq has a value of 9 (see 2 above), why does the if: qq = "9" test fail?

Am I missing something when trying to get this return value from exit "9"?
