i'm trying to figure out the macro basics & can't seem to find any simple
examples on the web or in the manual.  if someone could please post the
text of a simple *.do file that uses macros, i'd really really appreciate
it.  i'm using stata 7.

i'd also really appreciate any suggestions on my specific problem that i'm
trying to solve w/ macros:

to take variables (air_reg1, air_reg2, ..., air_reg24)
and (voc_reg1, ..., voc_reg24)

and to produce the sum of the products:

air_reg1*voc_reg1 + air_reg2*voc_reg2 + ... + air_reg24*voc_reg24

for a bunch of different sets of variables ({air,voc} is one example) w/ a
large dataset.

thanks so much!
