Is there a way to symbolic constants to have them stay correctly in place?

Hello Ruper, Barton:

Ok they have to get use to it! At least with Open Source like Maxima. Its
an old habit hard to kick when you get to be so used with commercial
software like MathCAD which I could control its appearance and the
worksheet itself becomes already publishable.

Thanks very much.
