Configuring the VRL mask subfield properties

VRL mask definitions can contain optional subfields. If a field contains subfields, then a unique subfield-separator character is required. This is defined in Mask Properties definition.

  1. To create a new mask subfield, select the mask folder in which to place the subfield and click New Subfield.
    To reconfiguring an existing mask subfield, select the subfield to reconfigure 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 subfield. This separates it from the previous subfield in the record layout. This value is optional.
  4. For Postfix, specify the characters that follow this subfield. This separates it from the next subfield in the record layout. This value is optional.
  5. For Min Width, specify the minimum width of the subfield, not including any prefix.
  6. For Max Width, specify the maximum width of the subfield, 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 SSF Sep, specify a subsubfield-separator character
    This must be different from the global Default Subfield Separator, which is listed on the Global Properties dialog box. This is located at Options > Global Properties.
    This must also be different from the field SF Sep character.
  8. 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.
