Unclassifiable Statement error in fortran 90

[Sandbox.WeC]

I'm writing this program for an assignment and I have run into a roadblock. I thought it was a pretty simple program, but I think my lack of experience with fortran is working against me.. Here is the bare code:

Program Readfile
implicit none
real(kind=8)::x,y,z,u,v
integer::n

OPEN(unit=12,file="file1.data")
OPEN(unit=13,file="file2.data")

read(12,*)
read(12,*)

DO n=1,38,1
read(12,*)x,y
z = LOG10[x]
u = LOG10[y]
v = LOG10[(x*x*x*y)/(1exp24)]
write(13,*)x,y,z,u,v
END DO

close(12)
close(13)
END PROGRAM

It is a simple concept. All it has to do is open file1 to get 2 values, then write in file2 those values, and a couple functions of them. The read(12,*) lines are used to skip the first two lines in file one, because they are junk. I am doing n=1,38 because there are 38 lines the program must do this to. The problem arises with the z= , u= , and v= statements. When I compile using the command gfortran file.f90 -o file.o it comes back and gives me Unclassifiable statement errors for all 3. What is my problem? Sorry if it is really obvious..

The [ ] should be ( ).

Also 1exp24 should be 1e24, unless 1exp24 is a F90 "enhancement" over F77 that I don't know about.

In addition to what AlephZero said, your first two READ statements are probably causing problems. These statements require one or more variables for the value(s) read to be stored in. I haven't written any fortran code for about 15 years, but I think this is correct.

Does your compiler give the line number of the unclassifiable statement? That would be helpful information.

In addition to what AlephZero said, your first two READ
statements are probably causing problems. These statements require one or more variables for the value(s) read to be stored in.

I think those are OK. They will read and ignore the first two lines of the file, assuming that's what the OP wants to do.

It seems like the issue may be with the syntax of your LOG10 function calls. In Fortran 90, the syntax for the LOG10 function is LOG10(x) where x is the value you want to take the logarithm of. So in your code, it should be z = LOG10(x), u = LOG10(y), and v = LOG10((x*x*x*y)/(1exp24)). Also, make sure you have defined the variables x, y, z, u, and v as real numbers before using them in the LOG10 function. Another possibility is that you may be missing a multiplication symbol between 1 and exp24 in your v statement. It should be 1*exp24. I hope this helps and good luck with your program!
