> Is that waht you are trying to do?

Thanks Paolo and David. That's not what I wanted to do but it did
help me out to produce the plot I want. I want to create a smallarray
vs. largearray plot but If I just tried to plot it, IDL will do what
it does best and plot only the first N_ELEMENTS(smallarray) points.
The code that I did come up with is as follows (It is very close to
what Paolo had):

l = FINDGEN(100)*0.5
s = [10.3, 9.6, 9.2, 8.5, 7.7, 6.9, 5.8, 5.4, 4.7, 4.1]
ns = N_ELEMENTS(s)
nl = N_ELEMENTS(l)

x = FINDGEN(ns)/(ns-1)
x2 = FINDGEN(nl)/nl

z = INTERPOL(s, x, x2)

PLOT, z, l, PSYM=-6

Thanks for your help,
Ryan.
