Syntax Item Subclass Properties
Syntax objects are characters that precede, separate, or follow a particular data
object. Item types with an Item Subclass of Syntax are defined and used to
specify delimiters, initiators, terminators, and release characters. Syntax objects
with variable values are defined as the syntax object’s Variable property. Syntax
objects appearing as actual data to be mapped as output data are defined as
components of a type.
Syntax Objects with Variable Values
Using a syntax item to specify delimiters, initiators, terminators, and release
characters is required when the value of syntax objects (delimiters, initiators,
terminators, and release characters) may vary.
The restrictions of syntax items define the variable literal values. For information
on defining restrictions, see Defining Item Restrictions.
Note The root type of a type tree may not have an Item Subclass of Syntax.
To define a variable syntax object
1 Create an item type with an Item Subclass of Syntax to represent the syntax
object.
2 Define the restrictions for the syntax item type.
3 For the item or group type with the variable syntax object, for the Variable
delimiter, initiator, terminator, and release character, select the item from the
Item drop-down list in the Properties window.
4 For the Find property, select Yes.
Note Only item types defined with an Item Subclass of Syntax appear in the
drop-down list.
