This document describes the IBM 16/32-bit Object Module Format and Linear eXecutable Module Format (LX).

The IBM 16/32-bit Object Module Format, also known as the IBM-OMF format. Also see Tool Interface Standards Portable Formats Specification, Tool Interface Standards Committee (Version 1.0), Section III for detail of the TIS-OMF format. Both OMF specifications are virtually identical but the TIS specification is the most current and is the specification used by most modern compilers for OS/2 such as IBM VisualAge C++ for OS/2.
