Yes, I have tried that: in "echo" it works but in a script command line for
some reason doesn't. If I use "set -x" to debug this is what I get 

++ echo ''\''TITLE "Average"'\'''
'TITLE "Average"'
++ PROG ''\''TITLE "Average"'\'''

And it gives an error, it seems that echo accept what it sees but a program
gets something different or is not equipped to accept it.

Even weirder the error is 

syntax error: 'TITLE "Average"' 

Which is the proper string, Probably reformatted in output or something....
I have no idea if it is possible to have <PROG  'TITLE "Average"'> as the
actual command, as if I use that synatx on the comman line it works.

Thanks for the help.
