Executive Systems Problem Oriented Language

From Wikipedia, the free encyclopedia
This is an old revision of this page, as edited by 91.36.229.212 (talk) at 15:00, 30 September 2011 (Abreviation for ESPOL was wong: Changed Programming -> Problem). The present address (URL) is a permanent link to this revision, which may differ significantly from the current revision.

ESPOL (short for Executive Systems Problem Oriented Language) was a superset of ALGOL 60 that provided capabilities of what would later be known as Mohols, machine oriented high order languages, such as interrupting a processor on a multiprocessor system (the Burroughs large systems were multiprocessor processor systems). It was used to write the MCP (Master Control Program) on the Burroughs B6700.

The single-pass compiler for ESPOL could compile over 250 lines per second.

ESPOL was superseded by NEWP.
