Grr, I wonder what I'm doing wrong.

I do have readline. I was running gp under emacs because that's what I
used to do; because I couldn't get it to work I thought I'd try
running it under readline (I've only just installed Linux and didn't
even know readline existed, let alone that I had it installed, until I
read the gp manual :) ). Actually, readline is very nice indeed and
did me just fine last night. The only time I missed emacs was when I
was looking at a huge output and was wondering whether it was a
polynomial in several variables or whether there were some furtive
denominators (e.g. (...+x^3+x/y+t^4+..)*z^6+..); I could have searched
for a / in emacs. Readline actually makes a huge difference, especially
when e.g. last night I wanted to execute the commands

f=subst(subst(subst(subst(f,x1,0),x2,0),y1,0),y2,0)
g=subst(subst(subst(subst(g,x1,0),x2,0),y1,0),y2,0)
h=subst(subst(subst(subst(h,x1,0),x2,0),y1,0),y2,0)
