Hi,

i have following example data:
x = [0,5,2,6,5,3,9]
y = [1,5,7,4,3,4,8]

to get the (x,y)-pairs in a special range i used the following:
points = WHERE((x LE (5))AND(x GE (2))AND(y LE (7))AND(y GE (3)),count)

Because i accept now the fact, that IDL works faster with array
operations instead of for-loops ;)
i want to do the following:
xy=[[0,5,2,6,5,3,9],[1,5,7,4,3,4,8]]

points=???

i tried
points= WHERE ((xy LE[5,7])AND(xy GE[2,3]),count)
but this dont works for me.

I know the solution is for sure simple one, but i cant find it.
THX for every idea.
