Distinguishing ERROR and ENDKEY

Progress treats the same ENDERROR key differently under different circumstances. This is why:

In determining whether the user pressed END–ERROR during the first or subsequent interaction in a block iteration, Progress does not count any keyboard entries to continue after a pause.
