Struct name field [initializer], field [initializer], ... EndStruct
Define a structure. A structure is a blueprint for a series of objects with an identical set of properties.
Lines after the Struct keyword define the properties (fields) that are part of the structure. Each line defines one or more fields, separated by commas.
A structure is instantiated with Dim:
Struct Pair First, Second EndStruct Dim p As Pair p->First := 1 % Set a field With p Do Second := 2 % Alternative version
Each field can have an optional initializer. See Dim for allowed forms of initializers. The initializer defines the initial value of the structure field. If no initializer is given, the field starts out EMPTY.
Internally, a structure is implemented as a constructor function. Instead of using Dim...As, you could also call the constructor function directly: p := Pair().
