Incorrect Error Message “DUP Record Too Large” on Structure ID Number: Q23613

4.00 MS-DOS buglist4.00 fixlist5.00

Question: A MASM program generates the error message “DUP record too large” on a structure filled with DBs and DWs. If each DB takes 1 byte and each DW takes 2 bytes, why should the structure not should take 119 bytes (which is well within the 512-byte limit)?

Response: The problem originates with the DBs and DWs taking up more memory than 1 and 2 bytes. Each DB uses between 60 and 90 bytes of memory. The problem is corrected in Version 5.00 of the Macro Assembler.
