VAR11.F Basic Object Variables Class

The VAR11 module provides an object variable superclass and several
specialized object variable classes including the Ptr class. Ptr class
variables are pointers into dynamically allocated memory. The Usefile
module creates a File Pointer Array in dynamically allocated memory
that is derived from the Ptr variable class. The File Pointer Array is a
key element in performing APM scans of data located in a text file.
