 /FIELD=(NAME=RECORD_TYPE,POS:1,SIZ:1)   ! Records type, one-byte field
 /FIELD=(NAME=PRICE,POS:2,SIZ:8)         ! Price field, both files
 /FIELD=(NAME=TAXES,POS:10,SIZ:5)        ! Taxes field, both files
 /FIELD=(NAME=STYLE_A,POS:15,SIZ:10)     ! Style field, format A file
 /FIELD=(NAME=STYLE_B,POS:20,SIZ:10)     ! Style field, format B file
 /FIELD=(NAME=ZIP_A,POS:25,SIZ:5)        ! Zip code field, format A file
 /FIELD=(NAME=ZIP_B,POS:15,SIZ:5)        ! Zip code field, format B file

 /CONDITION=(NAME=FORMAT_A,              ! Condition test, format A file
             TEST=(RECORD_TYPE EQ "A"))
 /CONDITION=(NAME=FORMAT_B,              ! Condition test, format B file
             TEST=(RECORD_TYPE EQ "B"))

           KEY=ZIP_A,
           DATA=PRICE,
           DATA=TAXES,
           DATA=STYLE_A,
           DATA=ZIP_A)

 /INCLUDE=(CONDITION=FORMAT_B,           ! Output format, type B records
           KEY=ZIP_B,
           DATA=PRICE,
           DATA=TAXES,
           DATA=STYLE_B,
           DATA=ZIP_B)

     In this example, two input files from two different branches of
     a real estate agency are sorted according to the instructions
     specified in a specification file. The records in the first
     file that begin with an A in the first position have this
     format:

       |A|PRICE|TAXES|STYLE|ZIP|
        1 2     10    15    25

     The records in the second file that begin with a B in the first
     position and have the style and zip code fields reversed, as
     follows:

       |B|PRICE|TAXES|ZIP|STYLE|
        1 2     10    15  20

     To sort these two files on the zip code field in the format
     of record A, first define the fields in both records with the
     /FIELD qualifiers. Then, specify a test to distinguish between
     the two types of records with the /CONDITION qualifiers.
     Finally, the /INCLUDE qualifiers change the record format of
     type B to record format of type A on output.

     Note that, if you specify either key or data fields in an
     /INCLUDE qualifier, you must explicitly specify all the key and
     data fields for the sort operation in the /INCLUDE qualifier.

     Also note that records that are not type A or type B are
     omitted from the sort.
