Thanks Chris, Eric, quoting the variable worked.

I use Mendel Cooper's Advanced Bash-Scripting Guide. In the    
following link, there is a discussion of the $IFS internal field
 
separator variable specific to echo and linefeeds. In general,  
I suppose that any command could replace echo and any $IFS    
characters (multiple spaces in my example) could replace
linefeeds.

Thank you. The following page from the scripting guide has a    

link to a Bash FAQ. The FAQ apparently has a complete listing   
of bash features that the traditional Bourne shell lacks.

The following page from the same guide lists command
interpreters    
and provides a Note that links to the POSIX specifications.
