Настоящее наследие
Шикарный пример legacy-системы, существующей с конца 1950-х годов -- система управления контрактами и соответствующего фин.учета в миноброны США. Вот цитата из предложения подряда на её модернизацию в 2016 году (т.е. спустя 60 лет).
The Mechanization of Contract Administration Services (MOCAS) system is an automated, integrated contract administration and
entitlement system, jointly owned by Defense Contract Management Agency (DCMA) and Defense Finance and Accounting Services
(DFAS). First launched in the late 1950s, the system is used for the administration, management, entitlement and disbursement of
complex contracts. The system consists of both online and batch system processing and is programmed primarily in COBOL, MANTIS,
JCL and Assembler mainframe languages.
