FileInfo function (was: Getting the type code of a file under OSX)

FlexibleLearning
Another one for the Scripter's Scrapbook! On the shoulders of Ken's fine  
stsFileInfo that retrieves file and folder attributes in an array format, I have  
below refined it to include any required attribute/s all in one command, in
any  combination and in any any order. The returned values are presented in the
 same order as requested.
 
Example:
 
put  flcFileInfo(myFilePath,"CreatorType","size","modified","permissions")
 
It also handles the change in the detailedFiles function, where  an
unsupported item is now 0 instead of empty (for example the 'BackUp Date'  under
Windows). It is, however, backwards compatibile with the earlier  detailedFiles
version.

Watch out for line-wrapping!
 
Optimising welcome.
