Dear all Same problem illustrated in a more simplified way. source code MODE=6 PSYDAT(6)=0.8524754597715760D-02 PSYDAT(7)=0.5159925701758463D+02 CALL PSYCHROMETRICS(TIME,INFO,IUNITS,MODE,WBMODE, & PSYDAT,EMODE,STATUS) write(myMessage,'(" PSYDAT(2)=",D," PSYDAT(6)=",D, & " PSYDAT(7)=",D)') PSYDAT(2),PSYDAT(6),PSYDAT(7) CALL MESSAGES(-1,trim(myMessage), & 'Notice',info(1),info(2)) simulation response *** Notice at time : 9.125000 Generated by Unit : 2 Generated by Type : 206 Message : PSYDAT(2)= 0.1732587158021238D+02 PSYDAT(6)= 0.8524754597715760D-02 PSYDAT(7)= 0.5159925701758463D+02 DB Temperature = 17.3°C instead of ~ 30°C for that state point. Is there any explanation? Thanks a lot.

Why the second PSYCHROMETRICS statement does not rewrite on PSYDAT(2)? Any help would be quite appreciated as I am slowly but surely getting crazy! Thanks a lot.
