[3] In putting out mainframe computer systems, General Electric, like other hardware vendors of the time, was providing software without cost to its customers.

[6] Initially, they intended to offer products for multiple vendors' platforms but soon found that economically it made sense to focus only on the dominant IBM mainframe.

[3] By 1976, Capex Corporation employed forty people, had sales offices in various cities in the United States and Canada, and had resellers overseas.

[3] Capex's products were focused on IBM's OS/MVS operating system and they benefited from having a sales force dedicated to selling on and for that platform.

[3] The COBOL (English-like programming language) Optimizer was first released in late 1970[2] and soon achieved visibility within the computing industry.

[11] These transformations also included avoiding loads from main memory into registers and improving how COBOL PERFORM statements were implemented.

[15] The Optimizer was a well-regarded and successful product that spent multiple years on Datapro Research Corporation's honor roll of software packages.

These included: Capex Corporation continued to grow and by 1982 employed 260 people,[27] while remaining privately held.

[3] It was announced in June 1982 that the company would be acquired by the Long Island firm, Computer Associates International, Inc.

[27] Capex continued to operate as a division of Computer Associates from their 14th Street Phoenix office until 1984 at the latest, when the remaining employees moved southward to an office near Interstate 10 and 24th Street, at which point the Computer Associates had fully subsumed the Capex brand.
