Remarks
This class provides methods for handling certain array operations that are not performed by Visual FoxPro array functions, including inserting and deleting specific array elements, and scanning an array by column.
To use, drop the class on a project or form or, from the Component Gallery Item Shortcut Menu, select Add to Project or Add to Form. When you add the class to a form, Visual FoxPro places the class icon on the form. You can specify the appropriate property values and provide any necessary input and output objects. When you drop the class on a project, you can choose between adding the class or creating a subclass.
