read binary data for integer and float types

Hi,

I have following script to read binary data in integer/float type.

two = new(2,"integer")
;two = fbindirread("data.bin",0,2,"integer")
jj = 67
ii = 43
rf = new((/jj,ii/),"float")
rf = fbindirread("data.bin",0,(/jj,ii/),"float")

Question (1),

Can fbindirread work without "(/jj,ii/)"? I tried and failed without it.

Question (2),

How can jj and ii be read from data.bin and then used to define jj and ii for rf = new(xxx) ?

Either
two = fbindirread("data.bin",0,2,"integer")
or
rf = fbindirread("data.bin",0,(/jj,ii/),"float")
works well separately.

But they do not work together (change 0 to 1 in rf line when both applied).

Thanks

Yongzuo
