History (up arrow/down arrow) while editing with Del editor.
I love the "up arrow" who recall last commands. but when I edit a Del function[quad] I also love the fact that I can edit/rewrite every lines in that function by doing up-arrow/down-arrow and typing over. but when I save the function with the final DEL, the history still remember the last 92 (in fact all) lines of the original function editing session, so, if I want to recall the line just before editing, I have to do 92+ up-arrow to get there .. I would love that in the Del editor, thoses (92) lines are not realy saved into the apl history. Completely useless. my whish, Xtian.
