  Sample input:
  Sample output:
of folder "Subfolder" of folder "MyFolder" of disk "External_HD"

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

AppleScript uses "reverse verbose" file paths like: folder "Some Folder" of folder "Enclosing Folder" of folder "Top Folder" of startup disk; or: folder "Some Folder" of folder "Enclosing Folder" of folder "Top Folder" of disk "External HD".

This fx takes Unix style paths such as "/Volumes/External HD/Top Folder/Enclosing Folder/Some Folder", or "/Applications/Quark/Subfolder" and returns the AppleScript equiv.

I needed to parse and reformat a FileMaker-formatted absolute file path into an AppleScript one. Since I'm novice to FileMaker, the only way I found to accomplish that was via a FM Script, although I tried to (and believe it is possible to) use a Custom Function to do the task. It took me about 9 minutes to script it in FileMaker 9.0v3. If you have any ideas or improvements, feel free to use them.

This does it in a CF, with the limitation that it must still be in a script, where a variable $Pos is first set to ""; or else in some context where there is no chance that $Pos will have a prior value. Requires sub-function ASFPCoreFx which is where $Pos is referenced; the reason I used a $variable in that CF is that I could find no other way to get the dialog to let me define a value (not previously identified) in terms of itself in a Let() function.

It is therefore still in need of improvement. But I was asked if such a fx existed; I assumed someone more adept than I am had posted one, but apparently not.

Well, no it doesn't. That is it can; but I can't think of any reason to ever use this format.

tell app "Finder" to get selection
-- document file "ab.jpg" of folder "Desktop" of folder "bruce" of folder "Users" of startup disk of application "Finder"}

tell app "Finder" to get selection as text
-- "Macintosh HD:Users:bruce:Desktop:ab.jpg"
