really stuck on last one (possibly two) .......... 24a In computer science, a programming tool used to turn higher level instructions into a form more suitable for the hardware (9)
26d A central European mountain range drained by the Rhone, Rhine and Reuss rivers (9,4)
I have "assembler" for 24a which leaves L?p?n?i?e ?l?s for 26d. I can't find solution, unless possibly "Appennine Alps" but then I am left with A?s?m?a?r for 24a.
