Sharing of workspaces in interactive processing using workspace name tables for linking of workspaces

摘要

An APL environment includes the usual workspaces plus so- called packaged workspaces. The disclosed packaged workspaces are load modules created from saved workspaces. An active APL workspace can access a loaded copy of the packaged workspaces using external names of named objects in a packaged workspace rather than internal names of its own named objects. Program execution associated with the packaged workspaces is controlled through a copy of the packaged workspace name table stored in the active workspace accessing the read only packaged workspace. Access to packaged workspaces not only can be concatenated from other packaged workspaces, but also can be shared among a plurality of active workspaces.
