Temperature in ocean script

I've got an ocean script by Session -> Save ocean script as following:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

simulator( 'spectre )
design( )
resultsDir( )
modelFile()
analysis('hb ?HBTranMode "Yes" ?tstab "50n" ?saveinit "yes"
?autoharms "yes" ?autotstab "" ?autosteady "yes" ?oversample list("1")
?fundfreqs list("(Frf)") ?maxharms list("5") ?errpreset "conservative" ?tstabmethod "gear2only" )
desVar( "vdda" 3.4 )
envOption(
'firstRun t
'cmd64bit t
'analysisOrder list("pz" "dcmatch" "stb" "tran" "envlp" "ac" "dc" "lf" "noise" "xf" "sp" "pss" "pac" "pstb" "pnoise" "pxf" "psp" "qpss" "qpac" "qpnoise" "qpxf" "qpsp" "hb" "hbac" "hbstb" "hbnoise" "hbxf" "sens" "acmatch")
)
option( 'pzSeverity "None"
'noiseSeverity "None"
'spSeverity "None"
'acSeverity "None"
'dcOpSeverity "None"
'dcSeverity "None"
'tranSeverity "None"
'temp "90"
)
option( ?categ 'turboOpts
'psrOption "Ultra Precision Analog"
)
saveOption( ?infoOptions list(list("modelParameter" "models" "rawfile" "" "" "" t) list("element" "inst" "rawfile" "" "" "" t) list("outputParameter" "output" "rawfile" "" "" "" t) list("designParamVals" "parameters" "rawfile" "" "" "" t) list("primitives" "primitives" "rawfile" "" "" "" t) list("subckts" "subckts" "rawfile" "" "" "" t) list("asserts" "assert" "rawfile" "" "" "" nil) list("extremeinfo" "all" "logfile" "" "yes" "" nil) list("simStatistics" "simstat" "rawfile" "" "" "" nil) list("allcap" "allcap" "file" "" "" "" nil) list("<Click_To_Add>" "none" "rawfile" "" "" "" nil) ) )
saveOption( 'nestlvl "4" )
save( 'v "/ant" "/rfin" "/vcc" )
save( 'i "/PORT0/PLUS" "/V0/PLUS" "/PORT1/PLUS" "/I51/I21/I9/M0/D" "/I51/I21/drn2" "/I51/I21/I9/M10/D" "/I51/I21/I9/M11/D" "/I51/vcc" "/I51/R20/PLUS" "/I51/R21/PLUS" "/I51/I21/I9/R9/PLUS" "/I51/I21/I9/R3/PLUS" "/I51/I21/I9/M0/DNW_ISO" "/I51/I21/I9/M0/SUB" )
temp( 90 )
run()

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

There are two lines marked in red that have temperature information. One is in the option() command, the other is the temp() command.

Why it set temperature two times? What's difference? If I want change the circuit temperature, should I have to change both of the two lines?

Either can be used, and the one that is used last wins. There's a specific temp() function because it is so common to change the temperature and so this makes it easier. When a simulator is integrated there is information given about how the temperature is set, and for spectre it is defined as setting the temp option; in other words if you call the temp() function, you can do ocnDisplay('option 'temp) and see that it's set the same as option('temp ...)
