I know. Also loading a program in PRGM mode shows the new step first after pressing SST. I have no solution for this. I can simulate a key press after loading, but there is no neutral key available.

That's simple – one of the prefix keys will do. You could simulate an [f] followed by [CL PRGM] which in RUN mode (!) is the official way of neutralizing a prefix key. Since there now is an elegant way of saving/loading programs by clicking the card slot, the two separate buttons could be removed. This way programs can only be loaded in RUN mode and the proposed method will work. You could also use another function that has no effect in RUN mode, e.g. one of the test commands.

If you want to load programs also in W/PRGM mode there is no need for a simulated key press since display, flags and trig mode it do not matter until the user switches back to RUN – which in turn makes the mode settings take effect. This means: if in RUN press [f] [CL PRGM] (or [f] [x=0?] or...), else do nothing.

I did not quite understand the other problem re. the next step after a SST.
