5.0 PLOT Command                                                                
                                                                                
     The PLOT command controls B34S line printer graphing and plotting          
options. For high resolution graphics (available on PC) see HRGRAPHICS          
option.                                                                         
                                                                                
     The general form of the PLOT command is:

The VAR sentence is required.                                                   
                                                                                
PLOT options:                                                                   
                                                                                
     GRAPH  -  Will make a X - Y plot of two variables on one page.             
                    This option is the default.                                 
                                                                                
     LPPLOT -  Will 'plot' up to 9 variables where each line                    
                    represents one observation                                  
                                                                                
     CSCALE -  Used with LPPLOT option. Sets common scale for all               
                    variables plotted.  The default is an individual            
                    scale.                                                      
                                                                                
PLOT parameters:                                                                
                                                                                
     IBEGIN=n1      Sets the beginning observation. Defaults to 1.              
                                                                                
     IEND=n2        Sets end observation. Defaults to number of obs in          
                    current dataset.                                            
                                                                                
     CHARACTER =    Sets character for LPPLOT. If CHARACTER parameter           
                    not supplied, defaults to 1 2 3 4 . Assume 4                
                    variables. CHARACTER=(M,Y,Z,Q) sets plot characters         
                    to M Y Z Q for first four series on the VAR command.        
                                                                                
VAR sentence.                                                                   
                                                                                
     The VAR sentence specifies the variables to use. If LPPLOT is set          
as an option, the maximum number of variables in the VAR sentence is 9.         
If GRAPH is set as an option, two variable names must be supplied in the        
VAR sentence.                                                                   
                                                                                
TITLE sentence.                                                                 
                                                                                
     TITLE=('    ') $                                                           
                                                                                
     The TITLE sentence allows the user to specify a title. The length          
of the title can be up to 80 characters long.  It must not contain a            
delimiter character ($) or the B34SEXEC or B34SEEND key words.

Note: Most users prefer high resolution plots. The advantage of the             
      PLOT command is the plots are in the output stream.
