TICKS incorrect on my 48SX?

[jbhp55]

In my case the elapsed time calculations went wrong, as soon as the elapsed time was more than 0.5 s. It seems the conversion B->R uses only the number in the stack, so if wordsize is 12, the resulting real is also never bigger than 4096. The stopwatch from the One Minute Marvels, for instance, does not work in that case.
I wonder why the previous owner had set the wordsize to 12.
