Your recursion to populate it is wasteful and doesn't enhance readability. For large trees, better hope you have some stack protection. A while() that modifies the working pointer and resets it to the root on every element change will most likely be faster, and also be less of a resource hog. (I'm really not trying to tear this article apart - I'm just hoping someone gets some good tips out of these, it is a helpful article.)

  hi,
  
  Thanks. For the info. The example was essentially some through away code to demonstrate the binary tree operation in Tcl.
  
  You're right on with the while() tip. I wanted the example code to be more explicit in the operation of the tree.
