COMMAND NAME:

        SAVE

USAGE:
        SAVE "savefile"

        The command records the state of the simulator in
        a file "savefile" during an interactive session. 
        This file can later be used to RESTORE the state of
        the simulator.  All simulator status is output to the
        file.
     
        This command may be used to store the status at any
        point during simulation. Hence simulation up to that
        point can subsequently be bypassed, dramatically
        reducing the amount of time required to reach a
        previously attained simulation state.
    
        If "savefile" already exists, it is overwritten.
    
        The contents of any output files which are open when 
        the SAVE command is invoked (e.g. simlst.dat) will not
        be stored in the status file and thus can not be
        RESTORED. When the status is RESTOREd, these files 
        will be reset, so any information in them will be
        lost.
