Identifier: scope
Identifier: scopeatable
The identifier table (atable) into which new identifiers without an atable prefix are stored. At the start of a command frame (procedure, macro, function etc.) scope has a value local.
The atable pointed to by scope is also added to the list of atables when looking for existing identifiers without an atable prefix.
When scope is changed within a command frame, its new value applies until the command frame is exited, and its value then reverts automatically to its value in the parent command frame.
