Syntactic Conventions
Fortran mode assumes that you follow certain conventions that simplify
the task of understanding a Fortran program well enough to indent it
properly:
- Two nested do loops never share a continue statement.
- Fortran keywords such as if, else, then, do
and others are written without embedded whitespace or line breaks.
Fortran compilers generally ignore whitespace outside of string
constants, but Fortran mode does not recognize these keywords if they
are not contiguous. Constructs such as else if or end do
are acceptable, but the second word should be on the same line as the
first and not on a continuation line.
If you fail to follow these conventions, the indentation commands may
indent some lines unaesthetically. However, a correct Fortran program
retains its meaning when reindented even if the conventions are not
followed.
