The previous reply is correct, you'll need to explicitly use multiplication signs in Fortran. Also, I would suggest (although plenty may disagree) that you use decimal points wherever they'd be applicable. So your equation line should probably be:

ptmp=(tmp(i)*((1000.0/prs(i))**k))

Let us know if you need more help!

dunno - consider using an operator '*' between the variables?

= tmp(i) * ((1000/prs(i))**k)

I need help with this error. I have just started using fortran, I'm a student and they asked us to use fortran 2.0. The program has to be able to give us the potentcial tempreture using this formula:

ptmp=(tmp(i)((1000/prs(i))**k))

here is the program

program upperairdata

implicit none

real, dimension(51) :: prs,hgt,tmp,dw,rh,mx,wd,ws
real :: sum,average,var,var1,var2,variance,stdev,ptmp,ptmp1,k
real :: AAA,maxim,minim
integer :: i,count
integer, parameter :: num=52
character :: header*1000,space3*3=' '

open(1,file='G:\WKD\Upperairdata\upperairdata.txt')
c read data
read(1,*)header
do i=2,num
read(1,*)prs(i),hgt(i),tmp(i),dw(i),rh(i),mx(i),wd(i),ws(i)
enddo

c print*,header
print*,prs(2),hgt(2),tmp(2),dw(2)
print *,prs(num),hgt(num),tmp(num),dw(num)

sum=0
do i=2,num
if(tmp(i).ne.(-99.99)) then
endif
sum=sum+tmp(i)
enddo

average=sum/(num-1)

if(maxim.lt.tmp(i))maxim=tmp(i)
if(tmp(i).ne.(-99.99)) then
if(minim.gt.tmp(i))minim=tmp(i)
endif
enddo
print*,'the maxim is',maxim,'and the minim is', minim

var=0
do i=2,num
if(tmp(i).ne.(-99.99)) then
endif
var1=(tmp(i)-average)**2
var2=var+var1
enddo
variance=var2/(num-1)
stdev=(sqrt(variance))
print*,'the variance is', variance

end program upperairdata
