QUESTION
 How can I stop VisualAge code from running if I get into an infinite
 loop?  Does VisualAge have something like CTRL-C?         
            
ANSWER                                                      
 VisualAge allows you to hit Alt+SysReq. 

 Hold this until you hear a low beep.  A debugger will appear 
 signalling that the process has been terminated/interrupted.
