How to plot in a dumb terminal ?

Hi,

I'm always working in text/mode; what I like with gnuplot
is that you can type 'set terminal dumb' and have your
graphics in text/mode. Pari-GP seems to do the same:
if I type 'plot(x=0,1,x^2)' I have what I want.
BUT:

how can I have the following specifications:

plot a function, say f(x) with
  x ONLY AN INTEGER from 0 to 100
    (because f(x) returns incoherent values if x isn't an integer;
    please, don't answer something like plot(x=0,100,f(round(x)))
    because f is quite long to compute, and I really don't want
    f(6) to be computed twice)
  the graphic should be in text/mode

Is there some README on internet that could help me to use the
plotting functions (text or html wanted; I know that almost
eveything concerning GP is in PDF, but I can't see it, just
print it :-(
