About this document

Nested Subprograms and Static Scoping by None None is a document available to read on EtoBox.

The document discusses nested subprograms and how they access non-local variables. It explains that activation record instances on the stack contain variables that can be accessed non-locally. For static scoping languages, a static chain of links between activation records allows finding the correct record containing a non-local variable, while dynamic scoping searches activation records on the dynamic chain.
