the FORM and INTV commands. See sections FORM on page 101 and
INTV on page 115.
Example:
>r
RH= 60.5 %RH T= 23.7 'C Tdf= 15.6 'C Td= 15.6 'C a= 13.0
g/m3 x= 11.1 g/kg Tw= 18.5 'C H2O= 17889 ppmV pw=
17.81 hPa pws= 29.43 hPa h= 52.3 kJ/kg dT= 8.1 'C
If a value is too long to fit to the allocated space in the output, or if there
is an error in outputting the quantity, the value is displayed with stars ‘*’.
Example:

RH=***.* %RH T= 31.0 'C
