Referencetoan

uninitialized

MWStruct

object to receive the

copy

Return Value. None

Remarks.

Clone allocates a new MWStruct object and creates a deep copy

of the o bject’s contents. Call this function when a separate object is required

instead of a shared copy of an existing o bject refere nce.

Example. The following Visual Basic example illu strates the difference

between assignment and

Clone for MWStruct objects:

Sub foo ()

Dim x1 As MWStruct

Dim x2 As MWStruct

Dim x3 As MWStruct

On Error Goto Handle_Error

Set x1 = new MWStruct

x1("name") = "John Smith"

x1("age") = 35

'Set reference of x1 to x2

Setx2=x1

'Create new object for x3 and copy contents of x1 into it

Call x1.Clone(x3)

'x2's "age" field is also modified 'x3's "age" field unchanged

x1("age") = 50

Exit Sub
