Error: Invalid character in name at (1)

Question

I am trying to compile a fortran file along with some .h files in FORTRAN. The .h files contain definition for common blocks of variable. When I compile them in Fortran, I get t

Answer 1

It looks like you are using Fortran 77 style line continuations and trying to compile with Fortran 90 style free format code. You either need to compile using the gfortran -ffixed-form option, or format the code using Fortran 90 style line continuations:

integer knue,ke,knumu,kmu,knutau,ktau,ku,kd,kc,ks,kt,kb,kgamma, &
          kw,kz,kgluon,kh1,kh2,kh3,khc,ksnue,kse1,kse2,ksnumu,ksmu1, &
          ksmu2,ksnutau,kstau1,kstau2,ksu1,ksu2,ksd1,ksd2,ksc1,ksc2, &
          kss1,kss2,kst1,kst2,ksb1,ksb2,kn1,kn2,kn3,kn4,kcha1,kcha2, &
          kgluin,kgold0,kgoldc 

Answer 2

I had this problem when modifying scipy and trying to compile it. The following identation was necessary to make it work, with the star * at column 5. It works for both Fortran 77 and 90 styles.

      double precision a,abseps,abserr,alist,area,area1,area12,area2,
     * a1,a2,b,blist,b1,b2,correc,dabs,defabs,defab1,defab2,d1mach,
     * dmax1,dres,elist,epmach,epsabs,epsrel,erlarg,erlast,errbnd,
     * errmax,error1,error2,erro12,errsum,ertest,f,oflow,resabs,
     * reseps,result,res3la,rlist,rlist2,small,uflow,areav

Answer 3

To your first question, yes the "1" normally denotes the point in the code where the error occurs. The code as such looks ok otherwise.

Answer 4

Actually the Fortran 77 continuation column is number six.
