-;;; Commentary:
-
-;; DCL mode is a package for editing
-;; [DCL](https://en.wikipedia.org/wiki/DIGITAL_Command_Language)
-;; command files.
-;; It helps you indent lines, add leading `$' and trailing `-', move
-;; around in the code and insert lexical functions.
-;;
-;; Type `C-h m' when you are editing a .COM file to get more
-;; information about this mode.
-;;
-;; Support for templates is based on the built-in tempo.el.
-;; I recommend setting (setq tempo-interactive t). This will make
-;; tempo prompt you for values to put in the blank spots in the templates.
-;;
-;; There is limited support for imenu.
-;;
-;; Any feedback will be welcomed. If you write functions for
-;; `dcl-calc-command-indent-function' or `dcl-calc-cont-indent-function',
-;; please send them to the maintainer.
-;;
-;;
-;; Ideas for improvement:
-;; * Better font-lock support.
-;; * Change meaning of `left margin' when dcl-tab-always-indent is nil.
-;; Consider the following line (`_' is the cursor):
-;; $ label: _ command
-;; Pressing tab with the cursor at the underline now inserts a tab.
-;; This should be part of the left margin and pressing tab should indent
-;; the line.
-;; * Make M-LFD work properly with comments in all cases. Now it only
-;; works on comment-only lines. But what is "properly"? New rules for
-;; indenting comments?
-;; * Even smarter indentation of continuation lines.
-;; * A delete-indentation function (M-^) that joins continued lines,
-;; including lines with end line comments?
-;; * Handle DECK/EOD.
-;; * `indent list' commands: C-M-q, C-u TAB. What is a list in DCL? One
-;; complete command line? A block? A subroutine?

-This mode indents command lines in blocks. (A block is commands between
-THEN-ELSE-ENDIF and between lines matching dcl-block-begin-regexp and
-dcl-block-end-regexp.)
-
-Labels are indented to a fixed position unless they begin or end a block.
-Whole-line comments (matching dcl-comment-line-regexp) are not indented.

-
-Variables controlling indentation style and extra features:
-
- dcl-basic-offset
- Extra indentation within blocks.
-
- dcl-continuation-offset
- Extra indentation for continued lines.
-
- dcl-margin-offset
- Indentation for the first command line in a file or SUBROUTINE.
-
- dcl-margin-label-offset
- Indentation for a label.
-
- dcl-comment-line-regexp
- Lines matching this regexp will not be indented.
-
- dcl-block-begin-regexp
- dcl-block-end-regexp
- Regexps that match command lines that begin and end, respectively,
- a block of command lines that will be given extra indentation.
- Command lines between THEN-ELSE-ENDIF are always indented; these variables
- make it possible to define other places to indent.
- Set to nil to disable this feature.
-
- dcl-calc-command-indent-function
- Can be set to a function that customizes indentation for command lines.
- Two such functions are included in the package:
- dcl-calc-command-indent-multiple
- dcl-calc-command-indent-hang
-
- dcl-calc-cont-indent-function
- Can be set to a function that customizes indentation for continued lines.
- One such function is included in the package:
- dcl-calc-cont-indent-relative (set by default)
-
- dcl-tab-always-indent
- If t, pressing TAB always indents the current line.
- If nil, pressing TAB indents the current line if point is at the left
- margin.
-
- dcl-electric-characters
- Non-nil causes lines to be indented at once when a label, ELSE or ENDIF is
- typed.
-
- dcl-electric-reindent-regexps
- Use this variable and function dcl-electric-character to customize
- which words trigger electric indentation.
-
- dcl-tempo-comma
- dcl-tempo-left-paren
- dcl-tempo-right-paren
- These variables control the look of expanded templates.
-
- dcl-imenu-generic-expression
- Default value for `imenu-generic-expression'. The default includes
- SUBROUTINE labels in the main listing and sub-listings for
- other labels, CALL, GOTO and GOSUB statements.
-
- dcl-imenu-label-labels
- dcl-imenu-label-goto
- dcl-imenu-label-gosub
- dcl-imenu-label-call
- Change the text that is used as sub-listing labels in imenu.
-
-Turning on DCL mode calls the value of the variable `dcl-mode-hook'
-with no args, if that value is non-nil.
-
-

-$! Next follows the first command line. It is indented dcl-margin-offset.
-$ i = 1
-$ ! Other comments are indented like command lines.
-$ ! A margin label indented dcl-margin-label-offset:
-$ label:
-$ if i.eq.1
-$ then
-$ ! Lines between THEN-ELSE and ELSE-ENDIF are
-$ ! indented dcl-basic-offset
-$ loop1: ! This matches dcl-block-begin-regexp...
-$ ! ...so this line is indented dcl-basic-offset
-$ text = \"This \" + - ! is a continued line
