A while ago I used an AppleScript to disable the Mac OS keyboard
shortcut Cmd-Tab, which cycles through open applications in order to
allow FileMaker to use that shortcut to cycle through records. I now
need to do it on another system and can't find where I saved it. Anyone
know of an Applescript or ResEdit trick to do this?

Why would you do this? Why not pick a key combo that is not used
by the OS, or instead of one that is already there (try using
Control + DownArrow for instance)

Sometimes I need to cycle through the open apps (and OK,
I guess I am not the typical user but ;-)

Cheers

FINALLY, I know the answer to something! The solution is not to disable
the cycling shortcut but instead to re-assign the keystroke combination.
I think it's an AppleScript that's buried somewhere in the Help folder
in the System Folder.

Save yourself a headache finding it and do this instead:
1) switch to the Finder and choose Help-->Mac Help.
2) do a search on "modify keyboard shortcut". The first result should be
"switching between open programs". Click it.
3) Scroll to the bottom of the page. Just above "Using the Application
Switcher to open documents" is a link that says "Help me modify the
keyboard shortcuts." Click it.
4) Let it walk you through. It will ask you first what modifier key to
use (control/command/option), then it will ask you what keystroke to use
to switch (\t for tab is the default). That's all there is to it!

I use option-tab to switch between applications, and I use the freeware
LiteSwitch control panel (http://proteron.com/liteswitch/) to get the
equivalent floating window that you get in Windows when switching
applications (LiteSwitch defaults to command-tab, so you'd need to
change it too, but it's a pulldown menu in the control panel).
