Well, that solves that. Thank you ! :) Perhaps youd care to update the manual: QPC2v2 supplement p13, states just that "..DISP_TYPE always returns 0." so naturally I didnt check. Per

Its probably the surest way, though somewhat gawky, dont you find? The Thing list is probably the one to use in these situations, but then there doesnt appear to be a GD2 Thing or anything related. An alternative might be to read the mode, though that is a rather indirect way of doing things, and not necessarily unambiguous with regard to the presence of the keyword in question. The keyword is directly related to certain capabilities of the OS, and it is those capabilities that I really want to test for. Are there no new keys in the sys vars to indicate the presence of GD2, like in the display mask (sys_mdsp) ? (Apparently not.) Just tested: Called iow.papp on a pre-colour SMSQ/E (this is the key for the first of the new traps). It didnt return NI, as might be expected, but BP (or is this a genuine BP error from some undocumented trrap?). Still, a utility or keyword to test for this might be a possible solution. Anyone know anything to the contrary? Later: Yes, I do! I wrote a SB keyword as described above. It worked as expected in various pre-colour versions of SMSQ/E, and on 2.98 in hi-colour mode - but not in 2.98 QL-colour mode - there the trap seems to work - ie no errors - although it isnt implemented! :(( Do we call this a "feature" or what? Other suggestions? Per

Re: [ql-users]GD2 again
Isn't there a way to check to see if a Keyword is available? In DJTK there is the CHECK command, that looks to see if a PROC/FN is available. I'm guessing this will work for the GD2 commands, like PALETTE_QL. Have not tried it myself, but it's worth a look. Get DJTK from Dilwyn's page on the Other Sofware page. Tim Swenson
Re: [ql-users]GD2 again
Whats the best way for programs to test for GD2? Suggestions for both SBasic and assembler welcome!
