Do loops like these:
DO
...
ENDDO
and
DO 100
...
100 CONTINUE
are probably not standard F77, but are used in existing code. both of these
work with g77.
Below is a (non) compilable example.
$ cat dl.f
I = 0
DO 10
IF (I.EQ.20) EXIT
I = I + 1
10 CONTINUE
PRINT*,'I is ',I
END
$ /usr/local/bin/gfortran -static dl.f
In file dl.f:2
DO 10
1
Error: Unclassifiable statement at (1)
In file dl.f:3
IF (I.EQ.20) EXIT
1
Error: EXIT statement at (1) is not within a loop
$ g77 -ff77 dl.f
$ ./a.out
I is 20
$ /usr/local/bin/gfortran --version

.. and this doesn't. I wrote the original code which supports the former, I will
take care of the latter once my copyright assignment is through.
