problem to use DRAW

As a beginner in open CASCADE and Linux (with the bash shell), i begun to install the PR2 binaries of open CASCADE.

After some research, i did some modification in the 'demo' script to be consistent with the bash shell.

Now, the 'demo' script is well interpreted, but an error occured when i enter 'axo' command (as adviced in the README file). Error message is 'invalid command name "axo" ', and it is the same when typing 'source demo.tcl'.

I suspect it is again a configuration problem, but from where ? Have you any idea ?

Thank you by advance
