IBM C/2

C compiler, debugger and IDE for development of 16 bit OS/2 and DOS code, based on an older Microsoft C compiler.

IBM's C/2 contains many additional features while maintaining a compatibility with former IBM PC C Compiler Version 1.0.

The product was withdrawn from marketing at 31 December 1997 and replaced by IBM VisualAge C++ that was already available from 1995.

Features

• Runs on and generates code for IBM OS/2 and IBM DOS (on 8086/88 machines only IBM DOS is supported)
• C/2 and generated code can run concurrently within OS/2's multi-tasking environment
• Support for multiple selectable memory models
• Library routines that provide greater program function
• Additional compiler switches
• enhanced MAKE utility (macros and inference rules)
• Interactive symbolic debug utility that allows isolation of program errors at the source code level (CodeView)
• EXEMOD utility for modification of DOS *.EXE file header
• Math Co-Processor support / Provides Math Co-Processor emulation

For creating Presentation Manager applications IBM C/2 Version 1.10 and IBM OS/2 Programmer Toolkit Version 1.1 are required.
