Relocatable Object Module Format CAH LLNAMES—Local Logical Names Definition Record Description The LLNAMES record is a list of local names that can be referenced by subsequent SEGDEF and GRPDEF records in the object module. The names are ordered by their occurrence, with the names in LNAMES records and referenced by index from subsequent records. More than one LNAMES and LLNAMES record may appear. The names themselves are used as segment, class, group, overlay, COMDAT, and selector names. History This record is an extension to the original set of 8086 object record types. It was added for Microsoft C 7.0. Record Format 1 2 1 1 CA Record String Name Checksum Length Length String Each name appears in count, char format, and a null name is valid. The character set is ASCII. Names can be up to 255 characters long. Notes Any LLNAMES records in an object module must appear before the records that refer to them. Previous versions limited the name string length to 254 characters. 68 OMF Specification, Version 1.1 Tool Interface Standards (TIS)
Relocatable Object Module Format CCH VERNUM - OMF Version Number Record Description The VERNUM record contains the version number of the object format generated. The version number is used to identify what version of the TIS-sponsored OMF was generated. History This is a new record that was approved by the Tool Interface Standards (TIS) Committee, an open industry standards body. Record Format 1 2 1 1 CC Record Version Version Checksum Length Length String The version string consists of 3 numbers separated by periods (.) as follows: .. The TIS Version Base is the base version of the OMF being used. This number is provided by the TIS Committee. The Vendor Number is assigned by TIS to allow extensions specific to a vendor. Finally, the Version is the Vendor-specific version. A Vendor Number or Version of zero (0) is reserved for TIS. For example, a version string of 1.0.0 indicates a TIS compliant version of the OMF without vendor additions. Tool Interface Standards (TIS) OMF Specification, Version 1.1 69
