Similar to THERMO(nnn,mmm),
except now three numbers are supplied, the starting temperature, nnn,
the step-size, mmm, and the ending temperature, lll.
If desired, the step-size can be lll and the ending temperature mmm.
The step-size cannot be less than 1K.
THERMO=(300,20,700) Start at 300K, end at 700K, and use a step-size of
20K. THERMO=(300,700,20) Start at 300K, end at 700K, and use a
step-size of 20K.
