change or add text in the window

[jfb]

I'm looking for a way to change the (static)text in the program window, something that can do this like in JB:

print #handle.ext, "a string"
This changes the text displayed on a statictext control. This command sets the contents (the visible label) of the statictext to be "a string". The handle must be of form #handle.ext that includes a unique extension so that commands can be printed to the control.

Thanks,
JFB

EDIT: I found the answer (it is no).
