Hello mj.cava,
You are absolutely right but it is no mistake. Just look on formula, I
have wrote, carefully. Today's date will be stored as 1010518.
Here are first and last records extracted from a f*.dat file of the real
database.
F1.DAT
00000000: 00 00 44 04 00 00 00 00 ¦ 00 00 00 00 00 00 00 00

The first record's date was stored as 90 D7 6C 94 = 970105
The last record's date was stored as 40 B5 76 94 = 1010516
Here are the Downloader explanations:

...........
05/16/2001 0.11000 0.11140 0.10850 0.10990 29070000 1093
Also look into a master file especially on 4 starting bytes. There are
a total number of the f*.dat files and highest number of the f*.dat.
Both numbers occupies 16 bits.

mc> Sorry Sergej, methink you are wrong :
mc> 1) The old database format (Equis/Computrac) is NOT Y2K compatible.
mc> Century=19 was assumed. Dates were saved as YYMMDD floating point values.
mc> 2) The old emaster and master files do use 8 bits (unsigned character) to
mc> store the security 'nnn' number (of Fnnn.dat)
