                  		FLUSHSYSOUT option controls the ability to view the progress of an active spool job. 
                  	 
 
            	 
            
               Syntax:
 
               		 
               		
                
                  		    
                  			 FLUSHSYSOUT 
                  			 = 
                  			  {  
                  				ON 
                        				 
                  			  }  
                  			  {  
                  				OFF 
                        				 
                  			  }  
                  		    
                  		
               
 
               	 
              
            	 
            
               Parameters:
 
               		 
               		
                
                  		   
                  			 
                  - ON 
                     			 
                  
- For active spool jobs, the buffer is flushed after each record is written, allowing you to view the contents of the spool
                     file as the job is in progress. 
                     			 
                  
- OFF 
                     			 
                  
- The buffer is flushed only when it is full, before which the contents of the spool file cannot be viewed. This option is more
                     performant. 
                     				
                     Note: The buffer size is determined by SEQDATBUF, and if that is not specify, a buffer size of 4096 bytes is used.
