Help on changing tcl prompt

[lihong pei]

Hi,
I'm not so familiar with Tcl. I would like to get some help regarding
changing tcl prompt.
From the online document, "tcl_prompt1" variable must be set and
associated with a tcl script to output a prompt.
However, I could not make it work.
If you have any experience of changing the prompt, could you help to
give some hint?

Thanks a lot in advance!

Just in case Don's advice doesn't work for you...

If you are changing the prompt within a procedure you
must also be aware that 'tcl_prompt1' is in the global
namespace, so the following will be required :

proc foo {} {
global tcl_prompt1
set tcl_prompt1 {puts -nonewline stdout "myprompt>"}
}

or

proc foo {} {
set ::tcl_prompt1 {puts -nonewline stdout "myprompt>"}
}

cheers,
Shaun
