The COMPUTE statement begins a compute block that produces a customized summary after each value of Manager. The LINE statement places the quoted text and the values of Manager and Sales.sum (with the formats $MGRFMT. and DOLLAR7.2) in the summary. An ENDCOMP statement must end the compute block. 
   compute after manager;
      line 'Subtotal for ' manager $mgrfmt. 'is ' 
            sales.sum dollar7.2 '.';
   endcomp;
