Is this correct?

Hello
I'll try to draw a Significant Tornado Parameter map:
http://www.spc.noaa.gov/exper/mesoanalysis/help/help_stor.html

This is part of script:

'define part1=(112+0.9*(tmp2m-273.15))*pow((rh2m/100),0.125)'
'define td=part1-112+0.1*(tmp2m-273.15)'
'define lcl=((tmp2m-273.15)-td)*125'

'define term1 = (capesfc/1500)'
'define term2 = ((2000-lcl)/1500)'
'define term3 = (srh1km/100)'
'define term4 = (shear06/20)'
'define term5 = ((200+cinsfc)/150)'

if ('lcl'<1000)
'define term2 = 1'
endif
if ('cinsfc'<-50)
'define term5 = 1'
endif
if ('term4'>1.5)
'define term4 = 1.5'
endif
if ('shear06'<12.5)
'define term4 = 0'
endif

'define stp = term1*term2*term3*term4*term5'

Is this correct? I'm afraid it's not :/
