Note that sed is only defined to work on text files and data files with the filename extension .dat are frequently binary files that do not meet the requirements of text files!
In what way is it "not working"?
Does it produce any diagnostic messages?
Does it just work on the first named file operand?
Is it using your editing command as a filename extension for your backup files instead of as an editing command?
If you're on a system using a BSD-based sed, does the command:
come closer to working for you?

EX(1) General Commands Manual EX(1)NAME
ex, edit - text editor
SYNOPSIS
ex [ - ] [ -v ] [ -t tag ] [ -r ] [ +command ] [ -l ] name ...
edit [ ex options ]
DESCRIPTION
Ex is the root of a family of editors: edit, ex and vi. Ex is a superset of ed, with the most notable extension being a display editing
facility. Display based editing is the focus of vi.
If you have not used ed, or are a casual user, you will find that the editor edit is convenient for you. It avoids some of the complexi-
ties of ex used mostly by systems programmers and persons very familiar with ed.
If you have a CRT terminal, you may wish to use a display based editor; in this case see vi(1), which is a command which focuses on the
display editing portion of ex.
DOCUMENTATION
The document Edit: A tutorial (USD:14) provides a comprehensive introduction to edit assuming no previous knowledge of computers or the
UNIX system.
The Ex Reference Manual - Version 3.7 (USD:16) is a comprehensive and complete manual for the command mode features of ex, but you cannot
learn to use the editor by reading it. For an introduction to more advanced forms of editing using the command mode of ex see the editing
documents written by Brian Kernighan for the editor ed; the material in the introductory and advanced documents works also with ex.
An Introduction to Display Editing with Vi (USD:15) introduces the display editor vi and provides reference material on vi. In addition,
the Vi Quick Reference card summarizes the commands of vi in a useful, functional way, and is useful with the Introduction.

Mark Horton has maintained the editor since version 2.7, adding macros, support for many unusual terminals, and other features such as word
abbreviation mode.
BUGS
The undo command causes all marks to be lost on lines changed and then restored if the marked lines were changed.
Undo never clears the buffer modified condition.
The z command prints a number of logical rather than physical lines. More than a screen full of output may result if long lines are
present.
File input/output errors don't print a name if the command line `-' option is used.
There is no easy way to do a single scan ignoring case.
The editor does not warn if text is placed in named buffers and not used before exiting the editor.
Null characters are discarded in input files, and cannot appear in resultant files.
