Continuing its concerted strategy to persuade mainframe users that object-oriented Cobol is the way forward, IBM Corp has added IBM Cobol set for AIX, VisualAge for OS/2 for Cobol and IBM Cobol for MVS implementations. The company said around 75% of the work that will eventually end up in the ANSI object Cobol standard is captured in the new releases – prices on AIX and OS/2 go from $900 per user, $540 for an introductory period.
