Not easily *within* gp (I may be missing something (*)) but certainly
*from* within gp, if you allow yourself to invoke awk or perl through
gp's extern() -- where it'll be a (long) one-liner.


(* for laughs: in fact if I take your question more literally than
you probably intended it, there is a trivial way to do it in gp --

parisize = 4000000, primelimit = 500000
(18:05) gp > pari()=["p","a","r","i"];
(18:06) gp > eval("pari")
%1 = ["p", "a", "r", "i"]

-- but I don't _quite_ think this is general enough for your purposes. ;)

Enjoy, Gerhard
