in thread [OT] Swapping buffers in place.

Your latter example a b c d e f 1 2 3 works for me calling swapbuffers 6, \@buffer. Your example looks as if you called swapbuffers 8, \@buffer. It also seems to be very similar to graff's proposal 1118234 that I do not quite understand still.

    You're exactly right! I changed the array, but not the number. I apologise. And thank you.

    I "understand" his logic; but coding it defeated me before I needed sleep.

    And I now appear to have two working solutions, so I may never go back to it...
