%R 
                         |  
                              
                     
This command causes INPUT statement repetition and
                      the output screen to be rebuilt. All output data generated from the beginning
                      of the INPUT statement will be reproduced.
               
By recording the terminal command %R, you can
                       manipulate a single step in a recording when it is played back.
               
You may also use %R to overwrite input data
                       in a recording that is being played back.
               
Further information on recording is provided in the section Natural Recording Utility in the Utilities documentation.
