Well, I had looked at the Modula mode (which looks very similar to
this Pascal mode), and then hacked up my own version of Pascal mode
with an emphasis on indentation and scanning begin-end blocks rather
than on producing templates for the various Pascal structured
statements (which to me seemed rather less useful).  Here's the
describe-mode output on my pas-mode; if folks are interested, I can
post my version (although it ain't quite as well finished as I might
have hoped for the purposes of distribution).  (I had mailed it out
once to someone who had requested it, but got no response nor ack.)
======================================================================
Pascal Mode:
Mode to support program development in Pascal.
The prefix-key for pas-mode is Ctrl-C.

  TAB            pas-indent-line  | Ctrl-c TAB     pas-tab-to-tab-col
  Ctrl-j         pas-newline      | Ctrl-c b       pas-begin
  Ctrl-c Ctrl-f  forward-block    | Ctrl-c Ctrl-b  backward-block
  Ctrl-c Ctrl-d  down-block       | Ctrl-c Ctrl-u  back-up-block
  Ctrl-c Ctrl-e  up-block         | Ctrl-c Ctrl-@  mark-block
  Ctrl-c Ctrl-n  narrow-to-block  | Ctrl-c ~       self-assign-stmt
  Ctrl-c Ctrl-[  open-comment-box | Ctrl-c Ctrl-m  continue-comment-box
  Ctrl-c }       pas-end-comment  | Ctrl-c >       set-end-comment-column

Variables:
  pas-indent controls the number of spaces for each indentation
  pas-tab-col controls the column to tab to using \C-c <TAB>
  end-comment-column controls the column on which comments will be closed
==============================================================================
Notes:
  * the "blocks" referred to are begin-end, case-end, record-end and
  repeat-until blocks; block-functions mirror lisp-mode functions

  * the self-assign-stmt is a simple hack to get the oft-used "x := x + 1"
  without having to retype the " := x " part of it; real useful when x
  is a long identifier or sequence of pointer-references.

  * pas-newline and pas-indent-line compute the correct indentation by
  referring to the indentation of the enclosing block.
