Well, you should be able to do this
puts "type your name"
puts -nonewline "> "
set num [gets stdin name]
puts "read $num bytes, name is \"$name\""
But there seems to be a bug in Jacl that does not allow this.
When I ran this test code I got a NullPointerException.
I am going to look into this and see if I can find where the
problem is.
