 NAME=condition-name

    Specifies the name of the condition you are testing. This
    condition-name can be used in /KEY, /DATA, /OMIT, and /INCLUDE
    qualifiers after it has been defined using the /CONDITION
    qualifier.

 TEST=(field-name operator test-condition)

    Specifies the conditional test.

 field-name

    Specifies the name of the field you are testing. The field-name
    must be defined previously by a /FIELD qualifier.

 operator

    Specifies the logical or relational operator used in the
    conditional test. The logical operators that you can use are
    AND and OR. The relational operators that you can specify are as
    follows:

    EQ       Equal to
    NE       Not equal to
    GT       Greater than
    GE       Greater than or equal to
    LT       Less than
    LE       Less than or equal to

 test-condition

    Specifies the constant or field-name against which you are
    testing. A constant is specified with the following format:

       Decimal_digits (default)
       %Ddecimal_digits
       %Ooctal_digits
       %Xhexadecimal_digits
       "character"

                                   NOTE

       Normally, you do not need to specify the radix operator
       (%D); however, test-condition will assume the same data type
       as the field-name.

    The field-name must be defined by a /FIELD qualifier.
