I suppose that with change of settings that is connected with g-code You mean changing the coordinates of pick and place points. I think that this can be done by feeding those values directly in HAL. Custom HAL components are written in C language and then compiled with EMC2. You can include command in the component to open a specific file and read it's contents. So in that file You can specify coordinates and add comments, which number means what so that in the end operator does not have to mess with HAL and it's components, but just turn off machine, close EMC, change the coordinates in a file and turn the machine on. > and the other is so that somewhat more complex > operations like dispensing adhesive or screwing parts together can be easily > accommodated with the same programming as simple motions.

Just as You mentioned - those additional moves are just moves, treat them as a usual move and feed the necessary information - target coordinate etc - from a separate file. > What I am wanting is actually the same thing that would be needed for a > multispindle, multiturret lathe.

If they are fed with one g-code file, where both spindles/turrets are moved by the same X, Y and Z functions then I see 2 issues there: 1) there must be some logic, which defines, which command will be executed by which spindle, this might be handled by M codes; 2) AFAIK, EMC will start executing next line only when previous is finished, it won't allow executing 2 lines at a time even if commands for spindle were written with X, Y and Z commands, but other - with U,V and W commands.
