Hi,  
I have the following requirement.

V="First"  
R="V"

echo $$R

The output should be First. How do i achieve this.

how do we evaluate the $R and evaluate it to $V as $R contains V  
and $V is First.

Thanks  
Vijay

```nohighlight
$ V="First"
$ R="V"
$ eval echo \$$R
First

```

If your version of ksh supports nameref

```nohighlight
$ V="First"
$ nameref R="V"
$ echo $R
First

```
