Wherever Restricted Plurals

The wherever statement restricts the application of plurals to the rows that respond true. Wherever restrictions can be used on any column except the row labels of labeded tables. The page on For restricted plurals explains why restriction is necessary. Like For, Wherever is a "conditional execution" statement which restricts the plural computation to only specified rows. The format of the statement is :

     Wherever logical expression Do:
          statement1;
              :
          statementn.
     elsewhere do:
          statementn+1;
              :
          statementm.
This statement tells the computer to execute the following
statements only for the responding rows.  For example:
     Wherever letter grade .ge. a Do:
          numeric grade = 4.0.
