Re: right justify - expounded

[Chris Bennett <chris@SYMBIOINC.COM>]

The following is a relevant message that Ray Ontko posted on this exact
question before (see the archives):

"Steve,

The short answer is "there's no easy way".  SQR doesn't "know"
anything about the widths of characters in proportional fonts,
so it doesn't support centering, wrapping, or right justifying
which requires knowledge of individual character widths.

For more background on the topic, search the archives for
"proportional font" at:

   http://www.sqrug.com/sqr-users/

If you MUST do it, there are a few routines that I and others
have written that do some of what you want (wrapping and truncation,
in particular).  You may be able to adapt them.  One is on the library
pages at www.sqrug.com, the other is at:
