1020:04a0	1020:049f	verified	borland_assign_text_short	bytes 1020:049f-04a1 decode as MOV DX,0xd233 at 049f and XOR DX,DX at 04a0; common body 04a2-04fb	Overlapping Borland runtime entry for Pascal ShortString names; containing ledger row accounts for the shared executable body.
1020:06b4	1020:06ab	verified	borland_create_generic_file	bytes 1020:06ab-06b9 select AH=3d/global access and empty-name handle 0 at 06ab or AH=3c/attributes 0 and empty-name handle 1 at 06b4; common body 06ba-070f	Overlapping Open/Create generic-file entry pair.
1020:0765	1020:0760	verified	borland_file_write_record	bytes 1020:0760-0769 select AH=3f/error 0x64 at 0760 or AH=40/error 0x65 at 0765; common body 076a-0795	Overlapping single-record Read/Write entry pair.
1020:079b	1020:0796	verified	borland_file_block_write	bytes 1020:0796-079f select BL=3f/error 0x64 at 0796 or BL=40/error 0x65 at 079b; common body 07a0-07fd	Overlapping BlockRead/BlockWrite entry pair.
1020:100f	1020:1017	verified	borland_real48_truncate_to_i32	bytes 1020:100f-1016 set CH=0, call conversion core 0f77, and RETF on success; bytes 101f-1024 are the Runtime Error 207 tail shared with Round entry 1017	disassembleOnly evidence was previously structural; readable Trunc semantics, overflow candidate, and shared error tail are now explicitly represented and DOSBox-differentially tested.
1020:1130	1020:111d	verified	borland_real48_sin	bytes 1020:111d-112f form the Cos-only pi/2-x prelude; 1130-1190 are a complete shared Sin body ending RETF; table 1191-11ba contains -1/15! through -1/3!	Exact modulo-2pi, quadrant folding, odd polynomial, small-argument bypass, half-cycle sign, and independent Sin entry are represented and differentially tested against original-offset bytes.
