TOTAL
Syntax:
  TOTAL field-name[,P][;field-name{,P}][;field-name{,P}] 
Where: 
 P = print a message (string) on the total line 
Placement: 
 Place the TOTAL command after the REPORT command and immediately after the PRINT command containing the fields you wish to total. 
Discussion: 
 The TOTAL command produces grand total, subtotals, and column totals.
 Follow the TOTAL command with the field-name or expression you wish to total.
 You can also use the optional "P" parameter to print a message or string value along with the total in the report.
You can use the BREAK and TOTAL commands together without a PRINT command to produce summary reports.
 A summary report provides one total line each time the data in the break field changes. 
Line continuation
To continue the TOTAL command to the next line, end the line with a ";" and continue on the next line.
