Fields

A Field behaves just like an APL variable.

To get the value of a Field, you reference its name; to set the value of a Field, you assign to its name. Conceptually, the Field value is stored in the Field. However, Fields differ from variables in that they possess characteristics that control their accessibility.

A Field may be declared anywhere in a Class script by a :Field statement. This specifies:

• the name of the Field
• whether the Field is Public or Private
• whether the Field is Instance or Shared
• whether or not the Field is ReadOnly
• the .NET type for the Field when the Class is exported as a .NET Assembly.
• optionally, an initial value for the Field.

Note that Triggers may be associated with Fields. See Trigger Fields for details.
