Note, though, that fixed-form is still in the Fortran standard, and still has the space-insensitivity. More popular for new programs, free-form is not space insensitive. Also, to make it easier for programmers, some space is still optional in free-form Fortran, for old and new keywords. For example, both GO TO and GOTO are allowed, I suspect with separate entries into the parsing tables. PL/I also has both GO TO and GOTO statements.
