You're absolutely right.  The advantage of using VARYING is that the 
system won't waste CPU cycles adding a bunch of unnecessary blanks to 
the end, and then calling QCMDEXC which wastes CPU cycles stripping them 
back off.

On the other hand, if you use VARYING, then the compiler will copy the 
string to a temporary variable before passing it, since the API doesn't 
actually call for a VARYING string.

If only the system would simply pass the address of the data portion of 
the string...   like %addr()+2.
