Variable variable name

Is it possible to use a variable whose name depends
on the value of another variable?

for example

i have variable j and variable i_0 ~ i_10
i want to use i_$j

Try the set command. For example, set i "the" ns_write "This is the variable for $i and $the_var: [set "[set i]_var"]"

That way should work but keep in mind that variables with Tcl may not start with a digit (as far as I know and as I expierienced).
