[WINTCL] Variable substitution

[Oleksiy B. <ole...@gm...>]

Dear all,

I have experienced the following problem:

Let we have several variables:

set a 1
set b 2
set c 3

and then we want to append these variables to a list:

foreach nm {a b c} {
     lappend dummy $nm
}

But it fails to do so and just put strings "a" ,"b" and "c" to the list
rather than their values.

I should very much appreciate for a suggestion on how to put values of
variables using "foreach" command.
