[SOLVED] Error message in Gfortran compilation needs interpretation.

AlexBB · 04-05-2015, 03:27 PM

My environment is Ubuntu 14.04 (just updated from 12.04), with the default gfortran 4.8.2.

I have this block of code:

Code:

    mod1 = MOD(couZero,100)
    if (mod1 == 0)                 <=== error         
      write (6,*) "couZero = ", couZero          
    endif
    if (MOD(couOne,100) .eq. 0)    <=== error
      write (6,*) "couOne = ", couOne
    endif

I get identical error messages on statements marked with left oriented arrows:

Code:

Error: Cannot assign to a named constant at (1)

What does the compiler want? How can I change this simple expression?

Thanks, - Alex

Sorry, it was a simple error. The code should be:

Code:

mod1 = MOD(couZero,100)
    if (mod1 == 0)  then                    
      write (6,*) "couZero = ", couZero          
    endif
    if (MOD(couOne,100) .eq. 0) then  
      write (6,*) "couOne = ", couOne
    endif

Keep forgetting once in a while.
