Turbo Pascal can import and link object files created with any other compiler that can create Relocatable Object Module Format file. OMF file is a collection of object records with the following format:

If local debug information is in enabled and comment class equals to ccSourceFile ($E8) this procedure processes object file COMENT record ($88). If source file number is 1, file name is copied to FileBuffer.

This procedure processes MODEND object file record ($8A) and updates statement code size symbol table.

This procedure processes EXTDEF object file record ($8C) and adds record to ExtrnDefinitions array for each EXTRN definition.

This procedure processes PUBDEF object file record ($90) and sets data in ProceduresRecord to the procedure defined in the object file.

This procedure processes LINNUM object file record ($94) and stores statement code sizes to the symbol table.

This procedure processes SEGDEF record ($98), finds appropriate Turbo Pascal segment and creates space in the symbol table for that segment.

This procedure processes FIXUPP record ($9C) and creates reference record in the symbol table.

This procedure processes LEDATA object file record ($A0) and copies data from object file to symbol table.
