Transaction field window options

Identifier
The name of the field parameter. When adding a field, this field contains the next available field parameter name, beginning with Field1.
Order
Determines where the indexing program extracts the beginning and ending index values. Choose By Row to extract the first value in the first row and the last value in the last row. Choose By Column to extract the first value in the first column and the last value in the last column.
Mask
Determines the pattern of symbols that the indexing program matches with data located in the field columns. If the transaction field contains variable length data (for example, a name field), the offset length can be adjusted by modifying the mask value. For example, you selected WAGNER in the report; the mask appears as @@@@@@. If a name can contain up to 15 bytes, then add nine @ (at symbols) to the mask field. The column offset end value is automatically adjusted. See Mask for more information.
Field Length
The number of bytes that the field occupies.
Column Offsets
Determines the location of the field from the beginning of the record. The Start value is the column at which point the field value begins. The End value is the last column of field data. You can define a maximum of eight pairs of beginning and ending offset values.
Add an Index on Exit
When this checkbox is selected and you click OK, the Add an Index window is displayed so that indexing parameters can be defined for the new field.

The checkbox is only applicable when adding a field.
