Description

A COBOL-85 compiler for 16 bit OS/2 and DOS introduced in 1988 as version 4 and with some limited Windows 3 support in version 4.5 introduced in 1990. In addition to adhering to the COBOL-85 standard the compiler comes with some support for IBM's DB/2 in version 4 and ANSI 85 definition, X/Open XPG3 COBOL definition, COMP-1 32 and 64 bit floating point extensions as in IBM OSVS COBOL and IBM VS COBOL II in version 4.5.

The actual compiler for versions 3 and higher was licensed from Microfocus, the rest of the tools like the debugger and editor were in-house developments from Microsoft, and earlier versions were ports of the old Microsoft Cobol-80 compiler.
