Your right I made the error above and I re-typed in the command line:
ls > $HOME/temp/l.txt
python
b...@sysero-rkm1laptop:~$ echo $HOME
/home/bobsysero
b...@sysero-rkm1laptop:~$ ls > $HOME/temp/l.txt
b...@sysero-rkm1laptop:~$ ls $HOME/temp
HelloWorld l.txt
b...@sysero-rkm1laptop:~$ python
Python 2.5.2 (r252:60911, Oct 5 2008, 19:29:17)

Traceback (most recent call last):

The error message if I am right in the command line is telling me that
python has no scope about $HOME and that is why I am getting the error.
In the demo HelloWorld in the main.py has in it:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import dabo
dabo.ui.loadUI("wx")
app = dabo.dApp()
# IMPORTANT! Change app.MainFormClass value to the name
# of the form class that you want to run when your
# application starts up.
app.MainFormClass = "HelloWorld.cdxml"
app.start()
When I ran the main.py from the command line I was getting the error
that Dabo could not open HelloWorld.cdxml.
Ed suggested that I place the code dabo.ui.info("HomeDirectory = %s" % hd)

In the command line I ran python main.py in the current directory and
the output from dabo.ui.info("HomeDirectory = %s" % hd) was:
/home/bobsysero/temp/HelloWorld/home/bobsysero/temp/HelloWorld
The Home directory should be: /home/bobsysero/temp/HelloWorld
I ran cd $HOME/src/dabo; svn up and the problem is solved.

You are also right that in testing and debugging you need to run in the
command line to find out what trace errors are coming back. Python is
new to me and I do like the trace back that you don't get in Java, C,
C++, Pascal, Fortran, Lisp and asm. For my end user they don't want to
see the terminal window so what I will do in Beta is redirect the output
to a file.
Thank you
Bob
