Improved efficiency of code; eliminated redundant
calculations performed if maximum specific conductance entered
exceeds 76,000 and added warning message regarding exceeding
maximum; corrected problem with code in handling starting
temperature or temperature increment with fractional part;
corrected off-by-one error in determining number of columns to
print in salinity correction factors table; improved error
checking and handling.
Version 1.1 1998/03/02
Modified code to insert commas in atmospheric pressure and
specific conductance values greater than 999.
