The BRADFORD font TECH.BF2 is a new addition to the many
fonts available for this excellent printing program.

The easiest way to generate formulas and equations with
TECH.BF2 is to write in all ASCII characters first and
then use the overline command and the font change command
to write in the Greek letters and technical symbols.  The
examples below show how this is done.

EXAMPLE 1: FRESNEL NUMBER FOR A LASER:

Write the formula like this,

         n (a ) \pr \fntech \pr \ov \pr \spq
             2  \pr \fnselect
    N   ------- \pr \fntech \pr \ov
      +         \pr \fnselect
          (L)   \pr \fntech \pr \ov
         l      \pr \fnselect \pr \sp1


to get a result which looks like this:


         n (a ) \fntech \ov \spq
             2  \fnselect
    N   ------- \fntech \ov
      +         \fnselect
          (L)   \fntech \ov
         l      \fnselect \sp1


EXAMPLE 2: STEFAN-BOLTZMANN Law:

Write

             P(Blackbody) =  T     \pr \fntech \pr \ov
                            s 4    \pr \fnselect
    Where
            P(Blackbody) = Total Power radiated (W/sq.m) \pr \fntech
                      s \pr \fnselect = 5.67E-8
            T = Temperature  K (C  + 273)\pr \fntech   \pr \ov
                              ,  ,       \pr \fnselect

to get

             P(Blackbody) =  T     \fntech \ov
                            s 4    \fnselect
    Where
            P(Blackbody) = Total Power radiated (W/sq.m) \fntech
                      s \fnselect = 5.67E-8
            T = Temperature  K (C  + 273)\fntech   \ov
                              ,  ,       \fnselect


Note that the new symbols are just under the spaces left
for them in the ASCII string; this method of superimposing
symbols avoids the problem of changing fonts in the middle
of a line and then trying to get everything lined up.  It
is not exactly WYSIWYG (What you see is what you get!), but
it's close.

Unfortunately, BRADFORD counts overstrikes as individual
lines even though they are not printed that way; partial
compensation for this problem is the use of the narrowest
line spacing (spq) when needed to make everything fit on
the same page.
