When [tclsh] is invoked interactively, it normally does not prompt 
when a newline is typed but the current command is not yet complete; 
if '''tcl_prompt2''' is set then its value is executed to create a prompt
that can remind the user to complete the current command.

If you have a useful script for '''tcl_prompt2''', perhaps you would consider sharing it with us?

Note: remember that anything output in the script will appear - even newlines. So if you want the prompt to appear at the beginning of the line to continue, and you want a space between the prompt and the input area, you will want to account for this in the script. For example, perhaps one might want to use

======
% set tcl_prompt2 {puts -nonewline ">> "}
% puts -nonewline ">> "
% set abc abc\
>> $
======

(where '''$''' represents my input cursor)
