Reading Values into Individual Array Elements [message #5927]

Hello,

I am trying to read values into an idl array and ran into the following
behavior.

I tried reading directly into an array using the following steps

IDL> a=make_array(5)
IDL> print,a
0.00000 0.00000 0.00000 0.00000 0.00000
IDL> read,a
: 1 2 3 4 5
IDL> print,a
1.00000 2.00000 3.00000 4.00000 5.00000

Which works as I expected.

However, when I try to use a specific element in the array as an
argument to the READ statement, IDL no longer prompts me for the
value but returns value of the element as shown below.

IDL> read,a(3)
4.00000IDL>

A workaround would be to use a scalar temporary variable and then
assign it to the specific element, but that seemed a bit circuitous
and not unlike other languages.

Is there something I am missing in this situation?

Thanks
