DBSRV50.exe -" windows 95 compatible" checkbox

I'm running an older version of software that accesses a Sybase DB using the DBSRV50.exe revision  I notice in the file properties there is a check box that is called "windows 95 compatible".  Since the client application appears to use 16 bit files like wod50w.dll to access the db, I was wondering if this engine is a 16 bit or 32 bit or both and what the check box is for?

Well, the Win 3.X executable versions had slightly different names the 32-bit  was DBENG50W.EXE and 16-bit DBENG50S.EXE

The non 3.X windows executable was simply DBENG50.EXE

So, while I wouldn't be surprised if it was really 16-bit under the hood, I would be inclined to say the version you have is 32 bit.

What is a little odd is the naming convention for wod50w.dll... For Windows 3.x, this driver is WOD50W.DLL in the WIN subdirectory BUT for Windows 95 and NT, the driver is WOD50T.DLL in the WIN32 subdirectory. Now, as an ODBC driver it probably lagged a little behind the 32 bit revolution and probably needed multiple versions...

Back to the DB engine... Most references I can find now say the path is typically : C:\SQLAny50\Win32\dbeng50.exe further encouraging the 32 bit resolve.

As for the "Windows 95 compatible" switch, cannot find anything concrete to go by...

That's a pretty old version! :) I think that's from 1996...?

If I remember correctly (I worked for Sybase then), the checkbox was in case you were an early adopter and using the bleeding-edge technology called Windows 95. I doubt it makes any difference to any modern OS.

I wouldn't at all be surprised if it was 16-bit, but I think given the maximum amount of memory it could use, it has to be 32-bit.

One thought... SQL anywhere 5.0 was one of the first to support mixed mode operating systems... So, might have been used to determine how (or what) it should be emulating with regard code pages and versions (like the 3.x variants) and such like...
