// THE_OMOCA_ENTRY_POINT(CDataSetDemo)
//
// This is the main object. A Moca project can have one and only one main
// object declared by the above command which communicates with Origin.
//---------------------------------------------------------------------------
MOCA_ENTRY_POINT(CFortran)


//---------------------------------------------------------------------------
// MOCA projects works with the aid of three types of tables
//		1) Property Tables
//		2) Methods Tables
//		3) Subobject Tables
//
// These tables are used for mapping LabTalk properties and methods to C++
// functions.
//
// 1) Properties(int, double or CString type as simple properties and functions with
//   arguments of above types as properties)
// 2) Methods(functions which accepts arguments from LabTalk)
// 3) Subobjects(Member Objects of the main Object and there member Objects....)
//   which can have there own properties, methods and subobjects.
// respectively. These Mappings are performed via. the Macros
// OMOCA_BEGIN_PROPERTY_MAP(CLASSNAME, BASECLASSNAME)
// ..........ENTRIES..................................
// OMOCA_END_PROPERTY_MAP(CLASSNAME, BASECLASSNAME)
// for property table, there are similar declaration for Methods and Subobjects
// Tables. The Entries can be of different types (See below) depending on the
// type of the arguments and access levels(Readonly or Writable)
// 
//  IMPORTANT!  IMPORTANT!  IMPORTANT!  IMPORTANT!  
// 
// Any class with subobject or methods table MUST have a property
// table, even if it has no entries!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//---------------------------------------------------------------------------


//---------------------------------------------------------------------------
// Property Map:
//
// The Property Map is for declaring the properties of your LabTalk object.
//
// A property is mapped to Get and Set function.  These functions allow
// you to do error checking or any necessary conversions.  A read-only
// property can be declared by using the _GET macro.
//
// MOCA_PROP_INT( <GetFunction>,<SetFunction>,<PropertyNameStr> )
// MOCA_PROP_REAL( <GetFunction>,<SetFunction>,<PropertyNameStr> )
// MOCA_PROP_STR( <GetFunction>,<SetFunction>,<PropertyNameStr> )
// MOCA_PROP_INT_GET( <GetFunction>,<PropertyNameStr> )
// MOCA_PROP_REAL_GET( <GetFunction>,<PropertyNameStr> )
// MOCA_PROP_STR_GET( <GetFunction>,<PropertyNameStr> )
//
// A Simple Property is mapped to a data member.  There are no Get/Set
// functions for a Simple Property.  MOCA will take care of the assignment.
// A simple read-only property can be declared by using the _GET macro.
//
// MOCA_SIMPLE_PROP_INT( <DataMember>,<PropertyNameStr> )
// MOCA_SIMPLE_PROP_REAL( <DataMember>,<PropertyNameStr> )
// MOCA_SIMPLE_PROP_STR( <DataMember>,<PropertyNameStr> )

// Method Map:
//
// INPORTANT: To have a Method Map or a SubObject Map, you must
// have a property map.
//
// MOCA_METHOD( <MemberFunction>,<MethodNameStr> )
//
// <MemberFunction> must be declared as "BOOL foo(double &, CStringArray &);"
// The double is used for storing LabTalk's return value.
// The CStringArray contains the arguments passed from LabTalk.
