I am not sure that I understand your problem correctly. However, I try

a=findgen(4,1000)

b=fltarr(2,*)

on the PV-WAVE and get

WAVE> a=findgen(4,1000)
WAVE> b=fltarr(2,*)

b=fltarr(2,*)
^
% Syntax error.

Obviously, 'b=fltarr(2,*)' is wrong. If we use size() to check the
dimensionality of a, we can find that a is a two dimensional array.

WAVE> print,size(a)
2 4 1000 4 4000

OK. If you want an one dimensional array, just use

WAVE> a=findgen(1000)
WAVE> print,size(a)
1 1000 4 1000

You now have an [1000] array.

Hans.
