Compiled object code is maintained in a format called OMF (Object Module Format), which is both the compiler output and the format used by the loader.  Various compilers are available, as well as utilities, notably the Collector, which links the code in several OMF modules into a single module, for more efficient loading at run-time, and the Module Amender, which allows patching of the instructions in an OMF module to fix bugs, using assembly language syntax.
