Go to in Fortran

[rajabadsha]

What would be the go to equivalent of Fortran into C?

goto - C has gotos too. There are several ways in which gotos are used

      do 10 i = 1,10, 1
         ...
         if (...) goto 10 ! equivalent of continue in C
         ...
         if (...) goto 20 ! equivalent of break in C
         ...
10    continue
20    continue

      if (.not. condition) goto 30 ! if (conditon) {
          ...
          goto 40                  ! }
30     continue                    ! else {
          ...
40     continue                    ! }

       goto 50                     ! goto L50
        ...
50     continue                    !L50:

       goto (n) 60, 70, 80         !switch (n) {
       ...                         !default:

       goto 90                     !break;
60     continue                    !case 1:
       ...
       goto 90                     ! break;
70     continue                    !case 2:
       ...
       goto 90                     !   break;
80     continue                    !case 3:
       ...
                                   !   break;
90     continue                    !}

There is also an assigned goto which is the similar to the computed goto.

THere is a Unix utility called f2c which will translate from Fortran 66 or 77 to C. Maybe you ought to try that one out.
