Hi-

If you try to assign any other value to x, it will give the same
error. e.g.
IDL>x = 2.2
IDL> read,format='(f10.3)',b
: x
% Unable to apply format code F to input: "x".
% Execution halted at: $MAIN$

The thing is, it doesn't accept any "variable" as input to READ or
READF. Why that ?

On my Linux, it runs fine. Also, I am generating NaN's in my code and
NaN is Not a Number, but indeed a value. It is not character or string
surely. I have whole data set as float and NaN is generated when there
is no data. So it is right alligned only, since it is treated as a
value. Now what ??
