Using Variables for dynamic Variable Names

Please see attached images... 1. I have local variables called $client1_ip, $client2_ip, $client3_ip, $cliept4_ip 2. I am trying to loop, using i as a varaible, and using each of those variables. Why is the way I am doing it not working? This is probably mostly a Tcl question... And YES I know I could have used an array of variables - but let's not go there.. :-) Just trying to figure THIS out with a dynamic variable name for now... :-) ![alt text][1] The 3 error(s) I get for the above are: ![alt text][2] Any clues on how to implement this correctly?

Hi Malli,

I deleted my earlier one as I was out of channel on that.

The above suggestion id not gonna work.

When i value would be 1 the result would be

$client1_ip
But it would not show the desired value

Sorry, I missed a command.

I was playing with

puts $[concat client$i\_ip]

I should try

eval puts $[concat client$i\_ip]

Got it.

Hi,

Try [subst \$client[subst $i]_ip]

First subst will subst value of i and second will for the whole variable.
