The following code first creates some table data and then displays all row numbers containing at least one column whose value is void :

service instruction_examples

   command next_repeat_example_1
      script
      
         // create table data provider with 2 rows and 4 columns, and containing some simple test data
         const positive32 row_count = 2
         const positive32 column_count = 4
         const table_data_provider table_data_provider = fa_table_data_provider_for_tests.co_create ( &
            i_row_count = c_row_count &
            i_column_count = c_column_count )

         // display all row numbers containing at least one void column

         repeat from row_index = 1 to c_row_count id: row_loop     // loop through all rows
            repeat from column_index = 1 to c_column_count         // loop through all columns
            
               const any_type cell_value = c_table_data_provider.co_cell_value ( &
                  i_row_index = c_row_index &
                  i_column_index = c_column_index )

               if c_cell_value =r void then
                  se_system.console.write_line ( "Row " & c_row_index.co_to_string & " contains at least one void column" )
                  next repeat row_loop
               end if

            end repeat
         end repeat
         
      end script
   end command
