Subject: Re: aligning and length statement
Leave the TRIM function out. The intermediate result reurned by TRIM has
no trailing blanks, so there is no "space" for the RIGHT function to shift.
In other words, RIGHT and TRIM provide alternative ways to get rid of
trailing blanks. If you apply one, there is nothing for the other to do.
