gnubol: cobol.el
Hey, guys -
This got bounced because I had the list set up to reject messages
over 40k, and this one was just over. I've changed the list settings now,
so this should go out. Sorry for the problems. (I trimmed the headers and
stuff up some too.)

Somehow or other, the attached message doesn't seem to have made it to
the list. Here's a copy--it should have the cobol.el attached, etc.
Hopefully if you use emacs, you know how to byte-compile Lisp source...
Also, you can add this to your .emacs, to make it start automagically in
cobol mode when you open a cobol file. I've done it the way I did it
because it's case-sensitive. I leave it to your own considerable
imagination to decide where in .emacs to put these, or what to modify.:

;;; [0) the left column is column 1]
;;; + 1) newline should indent to the same column as the start of
;;; the previous line
;;; + 2) tabs at 8 and every four thereafter (12, 16, 20, etc.)
;;; + 3) tabs should be expanded to spaces on input
;;; + (3a) no tabs should appear in the buffer
;;; no 4) right margin bell at 72 (hard to do)
;;; + 5) (optional) flash matching parentheses
;;; + 6) no auto-fill (WHY -- PWP) (not by default)
;;; * 7) auto startup on .cob files
;;; To do this, the expression ("\\.cob$" . cobol-mode) must be
;;; added to loaddefs.el in the gnu-emacs lisp directory, and
;;; loaddefs must be re-byte-code-compiled.
;;; Also, an autoload must be set up for cobol-mode in loaddefs.el;
;;; see the loaddefs.el file in this directory.
;;; + 8) auto indent to that of the last line (more magic than that...)
;;; + 9) delete on a blank line should go back to LAST tab stop
;;; + 10) C-c C-c moves cursor to ARG (or prompted) column, adding
;;; spaces to get there if needed
;;; 11) C-c C-l does (goto-line)

Variables controlling indentation style and extra features:
comment-start
Should allways be nil in Cobol mode. Cobol has no in-line comments.
cobol-do-indent
Extra indentation within do blocks. (default 4)
cobol-if-indent
Extra indentation within if blocks. (default 4)
cobol-continuation-indent
Extra indentation appled to continuation statements. (default 6)
cobol-indent-increment
Amount of indentation to add to a line when it can be indented (default 4)
cobol-comment-line-column
Amount of indentation for text within full-line comments. (default 6)
cobol-comment-indent-style
nil means don't change indentation of text in full-line comments,
fixed means indent that text at column cobol-comment-line-column
relative means indent at cobol-comment-line-column beyond the
indentation for a line of code.
Default value is fixed.
cobol-comment-indent-char
Character to be inserted instead of space for full-line comment
indentation. (default SPC)
cobol-minimum-statement-indent
Minimum indentation for cobol statements. (default 8)
cobol-line-number-indent
Maximum indentation for line numbers. A line number will get
less than this much indentation if necessary to avoid reaching
column 5. (default 1)
cobol-check-all-num-for-matching-do
Non-nil causes all numbered lines to be treated as possible 'continue'
statements. (default nil)
cobol-continuation-char
character to be inserted in column 5 of a continuation line.
(default is ?-)
cobol-comment-region
String inserted by \\[cobol-comment-region] at start of each line in
region. (default \" ** \")
cobol-electric-line-number
Non-nil causes line number digits to be moved to the correct column
as typed. (default t)
