>>Bits 16 and 256 return the same info for OS(10). Why then we have two of them? OS(10) returns 256 for me, which means I have it installed. However, DIRECTORY("T:\Images") returns .f., so I'm not connected to the server. Is it OK to just use directory even for non-existing drive?

Thanks a lot for your explanation. BTW, what about my second question? Looks like directory works fine with non-existing drives, so I may just use DIRECTORY to check if I'm connected.
