Ah, my fault. I forgot that we did not include the new traps into PTR_GEN for QDOS systems, it only provides a "GD2 light" with only enough functionality to make the new WMAN work. > Don't intend to - though it is nice to see QWord running on an Aurora > under Minerva or QDOS !! Actually I personally don't really like that. People should have incentives to do the switch to SMSQ/E. > I think my solution of (a) seeing if GD2 is supported and then (b) > try to use one of the new traps and see if there is an error return > will let me know whether I am running on a system without colour > drivers... Is this the right approach though? Of all the options you currently have this is actually a pretty good one. > Sorry - you are right - it is PTR_GEN I am interrogating - guess you > didn't look at the code snippets.

Guess it should be error -19 that > is returned...? It means "not implemented", yes. So you're right, you could do that.
