OMF 86 files contain a number of records, with each record having the following general format: ****************************************************** * record * record * record * checksum * * type * length * data * * * (1 byte) * (2 bytes) * (variable len) * (1 byte) * ****************************************************** The Intel specification for 8086 OMF is contained in: "8086 Relocatable Object Module Formats" Order Number 121748-001. This is the format used by the Intel development tools for the 8086/88/186/188's. Microsoft made some minor changes to OMF 86 for debugging support, and for libraries. There was an excellent article on OMF 86 and Microsoft's extensions in PC Tech Journal a number of years ago. Perhaps someone out there could post the issue number... Years ago, I wrote a utility that "dis-assembled" OMF 86 files. Unfortunately, I re-wrote it and the "new-and-improved" utility only dis-assembles OMF386. If someone is interested in finishing the code for OMF 86 files, e-mail me. Maybe the finished code would be a candidate for comp.sources.misc... --------------------------------------------------------------------------- Ed Braaten | "...
