Int 21 Fn 23 - DOS 1+ - Get File Size For Fcb [D]
AH = 23h
DS:DX -> unopened FCB (see AH=0Fh), wildcards not allowed
Return: AL = status
00h successful (matching file found)
FCB random record field filled with size in records, rounded up
to next full record
FFh failed (no matching file found)
Notes: not supported by MS Windows 3.0 DOSX.EXE DOS extender
MS-DOS returns nonsense if the FCB record number field is set to a very
large positive number, and status FFh if negative; DR-DOS returns the
correct file size in both cases
