INT 2F - DOS 4.0+ APPEND - SET RETURN FOUND NAME STATE AX = B711h Note: if the next INT 21h call (and ONLY the next) is function 3Dh, 43h, or 6Ch (also 4B03h and 4Eh if /X active), the fully qualified filename is written over top of the filename passed to the INT 21h call. The application must provide a sufficiently large buffer. This state is reset after the next INT 21h call processed by APPEND. APPEND uses the byte at offset 3Dh in the PSP (see #01378 at INT 21/AH=26h) to store the flag telling it to overwrite the filename BUG: DOS 4.0 APPEND reportedly overwrites DS:DX instead of DS:SI for INT 21/AH=6Ch SeeAlso: INT 21/AH=26h,INT 21/AH=4Eh
