31 ;; Fortran mode has been upgraded and is now maintained by Stephen A. Wood
32 ;; (saw@cebaf.gov). It now will use either fixed format continuation line
33 ;; markers (character in 6th column), or tab format continuation line style
34 ;; (digit after a TAB character.) A auto-fill mode has been added to
35 ;; automatically wrap fortran lines that get too long.
37 ;; We acknowledge many contributions and valuable suggestions by
38 ;; Lawrence R. Dodd, Ralf Fassel, Ralph Finch, Stephen Gildea,
39 ;; Dr. Anil Gokhale, Ulrich Mueller, Mark Neale, Eric Prestemon,
40 ;; Gary Sabot and Richard Stallman.

586 Normally nil in Fortran mode. If you want to use comments
587 starting with `!', set this to the string \"!\".
589 Extra indentation within do blocks. (default 3)
591 Extra indentation within if blocks. (default 3)
592 fortran-structure-indent
593 Extra indentation within structure, union, map and interface blocks.
595 fortran-continuation-indent
596 Extra indentation applied to continuation statements. (default 5)
597 fortran-comment-line-extra-indent
598 Amount of extra indentation for text within full-line comments. (default 0)
599 fortran-comment-indent-style
600 nil means don't change indentation of text in full-line comments,
601 fixed means indent that text at `fortran-comment-line-extra-indent' beyond
602 the value of `fortran-minimum-statement-indent-fixed' (for fixed
603 format continuation style) or `fortran-minimum-statement-indent-tab'

605 relative means indent at `fortran-comment-line-extra-indent' beyond the
606 indentation for a line of code.
608 fortran-comment-indent-char
609 Single-character string to be inserted instead of space for
610 full-line comment indentation. (default \" \")
611 fortran-minimum-statement-indent-fixed
612 Minimum indentation for Fortran statements in fixed format mode. (def.6)
613 fortran-minimum-statement-indent-tab
614 Minimum indentation for Fortran statements in TAB format mode. (default 9)
615 fortran-line-number-indent
616 Maximum indentation for line numbers. A line number will get
617 less than this much indentation if necessary to avoid reaching
618 column 5. (default 1)

620 Non-nil causes all numbered lines to be treated as possible \"continue\"
621 statements. (default nil)

623 Non-nil causes \\[fortran-indent-line] on an ENDIF statement to blink on
624 matching IF. Also, from an ENDDO statement, blink on matching DO [WHILE]
625 statement. (default nil)
626 fortran-continuation-string
627 Single-character string to be inserted in column 5 of a continuation
628 line. (default \"$\")

630 String inserted by \\[fortran-comment-region] at start of each line in
