DOS/4G and DOS/4GW FAQ:
Year 2000 compliance


[Previous Section] * [Index of FAQ] * [Next Section]
  1. Is DOS/4GW Year 2000 compliant?
  2. Is DOS/4G Year 2000 compliant?
  3. Will my DOS/4G(W) program be Year 2000 compliant?

1. Is DOS/4GW Year 2000 compliant?

Yes. DOS/4GW (and DOS/4GW Professional) do not use dates for any of their processing. Therefore, they are Year 2000 compliant.

They do pass the DOS interrupts relating to getting and setting the system dates through without processing. Since these interrupts should support dates through 2099, there is no Year 2000 problem -- unless DOS (or the DOS emulation you are using) is not Year 2000 compliant.


2. Is DOS/4G Year 2000 compliant?

Yes. DOS/4G, DOS/4G for Watcom and DOS/4G for Btrieve do not use dates for any of their processing. Therefore, they are Year 2000 compliant.

They do pass the DOS interrupts relating to getting and setting the system dates through without processing. Since these interrupts should support dates through 2099, there is no Year 2000 problem -- unless DOS (or the DOS emulation you are using) is not Year 2000 compliant.


3. Will my DOS/4G(W) program be Year 2000 compliant?

No, not automatically. Your DOS/4G(W) program depends upon a number of different systems: DOS and the BIOS (or the simulation you are using), DOS/4G(W), and your program's code. It will only be Year 2000 compliant if all three are.

Yes, as far as DOS/4G(W) is concerned.
