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