Examples

   1./FIELD=(NAME=SALARY,POSITION:10,DIGITS:8,DECIMAL)
     /KEY=(SALARY,DESCENDING)

     This /KEY qualifier specifies that the key field is SALARY and
     that the sorting order is descending.

   2./FIELD=(NAME=ZIP,POSITION:20,SIZE:6)
     /CONDITION=(NAME=LOCATION,
                 TEST=(ZIP EQ "01863"))
     /KEY=(IF LOCATION THEN 1
           ELSE 2)

     In this example, all the records with the zip code 01863 are
     to appear at the beginning of the sorted output file. The
     conditional test LOCATION (defined in a /CONDITION qualifier)
     is on the ZIP field (named in a /FIELD clause). The values of
     1 and 2 in this /KEY clause signify a relative order for those
     records that satisfy the condition and those that do not.
