in hierarchically structured memory systems, e.g. virtual memory systems

Introduced: January 1985

Full Title

Full titles differ between systems:

IPC:

Accessing, addressing or allocating within memory systems or architectures > Addressing or allocation; Relocation > in hierarchically structured memory systems, e.g. virtual memory systems

CPC:

Accessing, addressing or allocating within memory systems or architectures (digital input from, or digital output to record carriers, e.g. to disk storage units, G06F3/06) > Addressing or allocation; Relocation (program address sequencing G06F9/00; arrangements for selecting an address in a digital store G11C8/00) > in hierarchically structured memory systems, e.g. virtual memory systems

IPC and CPC are identically structured here. All 3 subcodes exist in both systems.

IPC defines codes here since 1985.
