Configure Defaults

This menu option allows a user to view and change Pablo System 
defaults.  These defaults control such things as locations for files 
and debugging status.  All these defaults may be changed, and the 
new defaults will take affect immediately.  

Execution Step Size refers to the number of records that Pablo will 
process before allowing itself to be interrupted by the X Windows 
system.   Other items are self-explanatory.

The defaults dealing with display update intervals, and the toggle 
button to animate graph execution are not used by the system at this 
time.
