Abstract
An address environment storage unit for a stack-oriented data processor for operating in data sets arranged as structured blocks, or nested pushdown stacks. The address environment storage employs a plurality of sets of display registers such that the current set of display registers does not have to be updated each time the processor moves to a different area of data in memory. The programmer only needs to provide a designation of a lexical level in a particular stack and the offset value from the base of the particular activation record in that stack for addition to obtain actual memory address. When the processor executes a procedure enter operator that calls for a new section of memory in which to operate, a display pointer is changed to point to the set of display registers provided for accessing that new area of memory.
