Thanks a lot! I will try it out tomorrow.

Why not. My daughter would love it ;P

Well, if one thinks in terms of a running script asking the user for  
whatever, it would be fine.
But I did play with an elder version (tm_read) and Rdaemon.
It seems that R (R running as daemon via spawn in an hidden pty)  
distinguishes between a 'read' coming from pipe as 'keyboard input'  
and the R command 'readline' which reads something from the keyboard.  
This led me to the assumption to use tm_interactive_input to solve a  
tiny problem - meaning whenever R executes the command readline,  
tm_interactive_input pops up a dialog to enter something. If there is  
a way to get rid of it - and there're a very few not only theoretical  
indications - then it would be nice not only to label the buttons but  
also to show only one button or even a NIB . ;)
[or a third button which kills the running process]

But back to the reality, I mean to be able to label the 'Send' button  
would be fine for now.

Thanks and mange tak,
