Could ABLE (lisp editor) be a good start point?

Oops, should have mentioned you have to use MzScheme v372.

Arc has mutable conses, so it would have been hard to make it work with versions of MzScheme after they switched to making lists immutable.

Install doc at top of arclanguage.org says to use 352, turns out to be issue with 64 bit systems.

-----

Use 352 with arc2.tar (the old, stable release), 372 with arc3.tar (the latest release, still being fixed).

Trying arc for the first time. Unable to get version 372 on my 64 bit systems.

Any way to get this to work with a later version of mzscheme?

How about http://download.plt-scheme.org/drscheme/plt-372-bin-x86_64-l... ?

Sadly Arc hasn't been ported to mzscheme version 4 yet.

Yes, but IMHO they are omogeneous with the other abbrevs in Arc sintax and are also conceptually clearer than car/cdr (that refer to old registers of an old pc): for example, hp (head of pair), tp (tail of pair) and hthtp (head tail head tail of pair) may help conceptual visualization...

Can anybody tell me where I could find discussion about this topic?

BTW, just to complete my previous example:

!hp for set-car !tp for set-cdr ?hp and similar for predicates...

Nice idea rewriting all book in Arc: OnArc!

Great! TIA
