问题
I am a little confused, with the PUBDEF record in the OMF object format. My assembler has generated a result which states the record is 4000 bytes, when it clearly is not so why would it do this?

The 0xa0 and 0x0f is the record length in little endian format,
please view the specificaiton: http://pierrelib.pagesperso-orange.fr/exec_formats/OMF_v1.1.pdf
It also appears to state that the strings are zero bytes in length and at one point even has just a zero string length with no string provided. Maybe I am reading the file wrong? I have spent hours now and am struggling.
If anyone can help me with my issue as I am writing a linker and cannot continue without understanding this.
Thanks

There is no PUBDEF record in the file. You seem to have miscalculated the previous record size:
0000:80 THEADR
000e:88 CoMENT
0032:96 LNAMES
0041:98 SEGDEF
004B:98 SEGDEF
0055:88 COMENT
005C:a0 LEDATA
006E:a0 LEDATA
007b:8a MODEND
Learn to use more sofisticated tools for OMF inspection, such as Tdump.exe or ODU.exe.
