Object in AWK

here is the small  illustration of what is object in awk:

 https://github.com/digics/UID10/POINTER.jpg

the ptr - is the any string that is used to address data in global arrays-fields
so the all object's data is always located in global arrays using ptr as the index:

FIELD[ ptr ]

passing ptr - meaning passing unlimited number of possible arrays or strings - that's is the object is

however to make an abstract unique string ptr "true"  pointer we need associate it with it's class udentifier - and that is differ true pointer from an unique string - it's mandatory association with the class

if ( ptr in CLASSPTR )

  # ptr is a pointer
 

This association with the class is what turns a simple string into a "true" pointer.
