Hi Jürgen:
Is there a way I can help with this? Which are the source files that implement the line editor?
On the assumption that the internal line editor should behave the way that the APL2 Editor 1 does -
for SVN 235 build 6472 on my Mac the internal line editor does not match the IBM APL2 Language Reference description of how their Editor 1 works. See page 391
