TCL : Concatenate a variable and a string

Question

Assume we have a variable \'a\' set to 12345 :

set a 12345

Now how do i set a new variable \'b\' which contains the value of \'a\' and anot

Answer 1

I don't get what you mean the direct string... I'm not sure if you want... However, if you want the value of 12349876 you can do:

% set b [concat $a$u]
12349876

If you want $a or $u to be part of the string, just add a backslash '\' before the desired variable.
