I have a file with 65 sets of 35 coordinates, and would like to isolate these coordinates so that I can easily copy the coordinates to another file.

resource
Resource(3I)Resource(3I)NAME
Resource - shared object
SYNOPSIS
#include <InterViews/resource.h>
DESCRIPTION
Resource is a class that provides a simple form of reference counting for shared objects. Every resource has a reference count that is
initially set to zero and must be explicitly incremented through a call to Reference. A resource should not be deleted like other objects;
instead, the static member function unref should be used to unreference the object.
When a resource is unreferenced, the reference count is decremented unless it is already zero. If the count is zero, the object is
destroyed.
PUBLIC OPERATIONS
Resource()
Create a new resource object with its reference count set to zero.
void ref()
Increment the resource's reference count.
void unref()
Decrement the resource's reference count, if it is positive, and delete this if the count is zero.
static void ref(Resource*)
If the resource is not nil, call ref on it. Otherwise do nothing.
static void unref(Resource*)
If the resource is not nil, call unref on it. Otherwise do nothing.
void Reference()
This function is equivalent to ref and is provided solely for backward compatibility. It will be removed in a future version.
void Unreference()
This function is equivalent to unref and is provided solely for backward compatibility. It will be removed in a future version.
FRIEND OPERATIONS
void Unref(Resource*)
This function is equivalent to static unref and is provided solely for backward compatibility. It will be removed in a future ver-
sion.
BUGS
This scheme relies on manual referencing, which is more efficient, but also more dangerous.
When garbage collection is supported by the runtime system, resources will be unnecessary.
