I was reading a 'hack', posted at ResExcllence, that explained how to protect an Extensions Manager Set using ResEdit.

Protect An Extension Manager Set

Instead of using ResEdit, I wrote a script that does the same thing. Please test it and give me some feedback.

<BLOCKQUOTE><font size="1"face="Geneva, Verdana, Arial">code:</font><HR><pre><font size=1 face=courier>(*This droplet will change a Read-only Extensions Manager Set to an Editable Extensions Manager Set and vice versa.*)
on open these_items
tell application <font color = red>"Finder"</font>
try
repeat with current_file in these_items
set item_info to info for current_file
if (file creator of item_info = <font color = red>"7INI"</font>) then
if (file type of item_info = <font color = red>"RSET"</font>) then
set the file type of current_file to <font color = red>"ESET"</font>
else if (file type of item_info = <font color = red>"ESET"</font>) then
set the file type of current_file to <font color = red>"RSET"</font>
end if
else
display dialog <font color = red>"The item, \"</font>" & (name of item_info) &
<font color = red>"\"</font> is not an Extensions Manager Set. Nothing will be done to this file." buttons
{<font color = red>"OK"</font>} default button <font color = blue>1</font> with icon <font color = blue>1</font>
end if
end repeat
end try
end tell
end open</font>[/code]

Also, does this post belong in the Classic Mac OS Forum?

Thanks

Your code crashes the Finder if anything dragged onto it is not an Extensions Manager set. Use this:

on open (A)
tell application "Finder"
set C to {}
set D to {}
repeat with B from 1 to (count A)
--try
set C to C & (item B of A as file specification)
--end try
end repeat
repeat with B from 1 to (count C)
if (item B of C as string) does not end with ":" and creator type of item B of C is "7INI" then
set D to D & item B of C
end if
end repeat
repeat with B from 1 to (count D)
if file type of item B of D is "ESET" then
set file type of item B of D to "RSET"
else
if file type of item B of D is "RSET" then
set file type of item B of D to "ESET"
end if
end if
end repeat
end tell
end open

Thanks for the feedback!
I'm an AppleScript novice, so it'll take me a little while to figure out your version. More than likely, I'll have some questions.

What OS did you test it with? I tested it in 9.1 and had no problems.

Are there subtle differences in scripting for OS 9.2.2? I upgraded (to 9.2.2) and ran into many instances where the Finder quit while I was running my scripts. I didn't find any benefits to 9.2.2 so I went back to 9.1. (I run 9 exclusively, no X - yet)

Are there any books you recommend? I've got "AppleScript For Dummies" by Tom Trinko, it's good for a beginner like me, except it's getting a little dated. I've also got "AppleScript In A Nutshell" by Bruce Perry, I haven't had a chance to read it cover to cover, but it tends to go 'over my head' quite a bit.

Yes, there are differences. I've had scripts break with the 9.1 to 9.2.x upgrade- very annoying.

I find macscripter.net a useful resource- I've gotten answers from the BBS there before, and it's a great source of osaxen.
