Structure Statement Summary

Structure is a terminal or nonterminal, declaration statement that occurs within Library statements and Class statements. Note that in description files authored from IDL-- i.e., external COM components -- there is also a Union statement (all members occupy the same location). In so far is gmBasic is concerned unions are treated in the same manner as structures. This statement has no refactoring or declaration flags associated with it.

The terminal form of the Structure statement is used to deal with the forward reference problems in library declarations. It is often the case that a member component of a type-defining component can have references to other types that have not yet been defined. Rather than trying to sort the type-defining declarations into a "reference" order, gmBasic, when it authors the declarations, places a set of terminal statements for all global type-defining components in the front of the library declaration with only the Id attribute specified. The later statements with the same Id then specify the remaining attributes and substatements.

The attributes of the Structure statement are as follows:
