Field References Made on Type 6 and Type 8 Parameters

The value of fields referenced during output phase processing on type 6 edit and type 8 process parameters depends on the following conditions:

• Whether the field is defined as a numeric or alphanumeric type 0 work field, type 1 work field, or input field
• Whether the field appears on a type 5 edit parameter
• Whether the field appears on a SORT parameter

The value of a field referenced during the output phase under the above conditions will be one of the following types of values:

• A column total
• A sort-key value
• A current value of a type 1 work field
• A current value of a type 0 work field

The following table summarizes values assigned to input and work fields during the output phase.

Notes:

N = Numeric field
A = Alphanumeric field
Sort-key value = Value of sort key at the control break
Column total = Total of items extracted on a type 5 edit parameter
Current value = Value of the named work field

Each type of output phase field value is described as follows:

Column Total

A field is assigned a column total if the field is a numeric input or work field that is specified on a type 5 edit parameter. A reference to the field on a type 6 edit parameter or type 8 process parameter obtains the sum of all detail occurrences of the field for the current control break. This is true even for numeric fields that specify format codes FD (date), FS (social security number), and FM (edit mask).

Fields in this category cannot be specified as result fields on a type 8 process parameter. Fields in this category that appear on a SORT parameter are sorted by the extracted value of the field. The value of the field as a sort key, however, cannot be obtained by a reference on a type 6 edit parameter or type 8 process parameter.

Sort-key Value

A field is assigned a sort-key value if it is one of the following:

• A numeric input or work field that appears on a SORT parameter but does not appear on a type 5 edit parameter
• An alphanumeric input or work field that appears on a SORT parameter

A field in this category that is referenced on a type 6 edit parameter or type 8 process parameter is assigned the value of the sort key associated with the last detail line processed before the current control break. Fields in this category cannot be result fields on a type 8 process parameter.

Work Field

A field is assigned the current value of a type 0 or type 1 work field if it is one of the following:

• A numeric work field that does not appear on a SORT parameter or on a type 5 edit parameter
• An alphanumeric work field that does not appear on a SORT parameter

A field in this category that is referenced on a type 6 edit parameter or type 8 process parameter is assigned the current value of the work field. The current value depends on the type of work field, as follows:

• If the work field is a type 0 parameter, the field value at the start of the output phase is the value at the end of the extract phase.
• If the work field is a type 1 parameter, the field value at the start of the output phase is the value at the beginning of the extract phase.

The subscript of a subscripted work field is interpreted as a pointer to an occurrence in an array that holds the current values of the work field. The subscript must be a numeric literal or a numeric work field that does not appear on a type 5 edit parameter or on a SORT parameter and that does not specify a decimal point.

A reference to a field is invalid on a type 6 or type 8 parameter if the field is one of the following:

• A numeric input field that does not appear on a SORT parameter or on a type 5 edit parameter
• An alphanumeric input field that does not appear on a SORT parameter
