Structure-Pointing Atoms Graphs and Terminology of SPL Trees Staying in Context Isolated Cells

A compiler source language and internal organization are described, which utilize program block structure to provide a virtual memory capability for linked-list hie.rarchically structured data. A nonprocedural source language notation is introduced, resembling conventional mathematical set notation, for describing the search and selection of the members of subsets of ordered sets. An algorithm is presented for the translation of these statements into conventional compiler loop statements. Some convenience features in compiler source language notation are introduced, including the ability for the compiler to %tay in contexttl with the programmer. One partial implementation of the compiler is outlined.
