A line can be up to 132 characters.  In the F90 fixed form lines are
continued by using an & character at the end of the line and optionally
at the start of the next line.  Character constants require the & at the
start of the next line (so the compiler knows whether or not leading
blanks are significant.)

So, you could do yours as:
 PRINT *,'---------------------------------------------------&
     &------------------------------------------------------------&
&---------------------------------------------------------------------'

As a matter of style I like to use concatination for continuing
characters.  Something like:

 PRINT *,'---------------------------------------------------'//   &
 '------------------------------------------------------------'//  &
'---------------------------------------------------------------------'
because the rules for where the & must go and what to do about leading
blanks and trailing comments seem easier to me.

For your specific example, something like
    print '(150a)', ('-', i = 1,100)  
might be better.  It's more compact, and it's obvious that you will
get 100 dasheson the output line.
