Configuring the VRL mask subsubfield properties

Each VRL subfield can contain subsubfields. If a subfield contains subsubfields, then a subsubfield-separator character is required. This is defined in Subfield Properties definition. Do not use the same subsubfield-separator character as the field separator or the subfield separator.

  1. To creat a new mask subsubfield,s elect the subfield in which to place the subsubfield and click New Subsubfield.
    To reconfigure an existing mask subsubfield, select the subsubfield to be reconfigured and edit as necessary.
  2. For Data Type, click the arrow to select from a menu of data types.
  3. For Prefix, specify the characters that precede this subsubfield. This separates it from the previous subsubfield in the record layout. This value is optional.
  4. For Postfix, specify the characters that follow this subsubfield. This separates it from the next subsubfield in the record layout. This value is optional.
  5. For Min Width, specify the minimum width of the subsubfield, not including any prefix.
  6. For Max Width, specify the maximum width of the subsubfield, not including any prefix. To disable, specify a value of -1. This is the default. For a specific width, specify the value. Incoming data larger than that value is truncated.
  7. For validation, select how to validate the subfield data whenever this record layout is used as an input or output record:
    Existence validates the existence of the data, but not its content.
    Contents validates the type of data, but not its existence.
    Existence and Contents validate both the existence and the content of the data.
