| Type | | Description |
| THEADR | 1 | Marks the start of an object module, contains the name of the source file. |
| COMENT, class A1h | 1 | MS extension; tells linker the CodeView version number. Emitted if -Zi option is active. |
| COMENT, class E9h | n | Borland-style auto-dependency record(s). Emitted if -Zd or -Zi options are active. |
| COMENT, class 9Eh | 1 | MS extension; directs the linker to use a "standardized" segment ordering. Emitted if the .DOSSEG directive is found in the source. |
| COMENT, class 9Fh | n | Default library search name(s). Emitted if INCLUDELIB directives are used. |
| LNAMES | n | Defines names for segments and groups ( optionally also for externals, communals and publics ). |
| SEGDEF | n | Defines segment(s). |
| COMENT, class FEh | n | Tells WLink to do FARCALL optimization for a specific segment. Suppressed with -zld. |
| GRPDEF | n | Defines group(s). |
| EXTDEF | n | Defines external(s). |
| COMENT, class A8h | n | Defines weak external(s). Emitted if EXTERN directive is used with "altname". |
| COMDEF | n | Defines communal(s). |
| ALIAS | n | Defines alias(es). |
| PUBDEF | n | Defines public(s). |
| COMENT, class A0h | n | Defines export(s). Emitted if the EXPORT attribute is used in a PROC directive. |
| COMENT, class A2h | 1 | Link Pass Separator. Emitted if no entry point is defined in this object module. |
| LEDATA | n | Data record; defines segment content(s). |
| FIXUPP | n | Contains information to make the linker resolve references between object modules. |
| LINNUM | n | Line number information. Emitted if -Zd or -Zi option is active. |
| COMENT, class FDh | n | Tells disassembler that a code segment contains data. Suppressed with -zlc. |
| MODEND | 1 | Marks the end of the object module; optionally defines the entry point. |
LEDATA, FIXUPP and LINNUM records usually are intermixed; a FIXUPP and/or a LINNUM record appears immediately after
the LEDATA record to which it refers.
