pclose

 PCLOSE STATUS -- Sets PCLOSE flag which determines whether plots are
                  closed on exiting commands or not.

 If you want to add labels to a plot or draw another plot on top of
 one you need to set pclose BEFORE making a plot (slight change from
 before where you could do it afterwards). If you do this then you must 
 explicitly 'close' the plot if you want a hardcopy.

 Parameters:  

 STATUS -- If not supplied by user, the status of PCLOSE is just switched
           Otherwise put STATUS = 'ON' or 'OFF' to force the required state.
