Isn't, there is no action switch.
Some assumptions:
1. You selected "open" as the action for *.doc
2. You edited "open"
The command line then should be...
"C:\Program Files\Accessories\WORDPAD.EXE " "%1"
3. You set "open" as the default.
Left clicking a doc file will then open the file with Wordpad.
Again, I urge you *NOT* to try to change file type associations via
"Settings|File types" but to use the "Shift+right click | Open with" as
explained previously.

It wasn't the install that messed you up, it was the *uninstall*. It
messed you up because you didn't go back to square one association-wise
*before* uninstalling. Most programs that grab extensions have an
option somewhere to select extensions grabbed and/or a way to ungrab
them.
The association was wrong because you had installed a program to which
you (or the program) assigned a file type. When you uninstalled it the
file type was orphaned - nothing to open it.
Normally, that is no problem because most programs create their own
unique file type(s). The problem arises when you have multiple programs
that operate on one file type....txt, doc, htm, rtf, jpg, bmp, etc.
Multiple programs can *use* a given file type but only one can be the
*default" program...the one that opens a file when you click on it.
If the program you installed grabbed a common extension automatically
and had no "ungrab" option then a soupcon of thought on your part should
have told you that if you uninstall the program then the common file
type would be left dangling with nothing to open it. Solution?
Re-associate it via Shift + right click|Open with...
Now, one could say that the program's uninstall should have
re-associated the file type(s). That's true. But iron rusts...life
isn't fair...and there are a lot of programs written by people who have
little knowledge of what they do. The fact of the matter is that many
(most?) programs leave residual junk when uninstalled. And it makes no
difference whether it is uninstalled with the program's uninstall or via
"Control Panel|Add/remove programs" because all the latter does is use
the former.
The way to get a nice, clean uninstall of any program is to monitor
*all* installs with TotalUninstall and to also use it to *uninstall*
monitored programs. When used properly, whatever it has monitored will
be removed/reverted.

Finally, if you ignore my suggestion to set file type associations via
"shift+right click|open with" and use "Settings|File types" there are
two apps that make the file type editing a bit easier. Both have decent
help files which should be *READ*.
