On RISC machines:

                  Current Unprotected                 
                                                              
  The current amount (in millions of bytes) of storage in     
  use for temporary objects and machine data on the system.   
 
                  Maximum Unprotected               
                                                          
  The largest amount (in millions of bytes) of storage used 
  for temporary objects at any one time since the last IPL. 

On CISC machines:

                  Current Unprotected               
                                                          
  The current amount of storage (in millions of bytes) in   
  use for temporary objects and machine data that are stored
  in unprotected storage when system checksum protection is 
  in effect.  This is used in conjunction with maximum      
  unprotected storage to determine how much unprotected     
  storage should be reserved when the checksum protection   
  provided by the system software is started.               

                  Maximum Unprotected                
                                                          
  The largest amount of storage (in millions of bytes - for 
  temporary objects and machine data that are stored in     
  unprotected storage when the checksum protection provided 
  by the system software is in effect) used at any one time 
  since the last IPL.                                                    

I believe on CISC machines that DIDN'T have checksum protection, that
this size was actually the size of your load source disk drive (first
drive) PLUS the temporary/machine data
space.
