As far as I know, Geoff, it's a sort-of crossy platformy databasey formaty thingy. Or is that too technical for you?

It's pretty good at accepting any sort of thing like lots of text and searching it quickly - so that's why DT used the old DOS version. There's a Windows version (askSam for Windows v2.0b) which I got off a free disc some time ago - if you're interested I'll pass it on, or you might get it on a download.
