Good!

Today I noticed a fourth approach in Oberon.TextDocs.Mod.
"(** Starts searching for textual differences starting at the selection 
  positions of the last two selected texts
		Call: TextDocs.SearchDiff(** Starts searching for textual differences 
		  starting at the selection positions of the last two selected texts
		Call: TextDocs.SearchDiff [text1 text2]			exact comparison
				TextDocs.SearchDiff \w [text1 text2]		compare ignoring 'white space'
*)
PROCEDURE SearchDiff*;"

To see the module, open 
https://svn-dept.inf.ethz.ch/svn/lecturers/a2/trunk/source/ 
and supply userid infsvn.anonymous and password anonymous. In the 
resultant list of sources click on Oberon.TextDocs.Mod.

At each difference, the two selections must be reset to continue.  
Automation of the reset may be possible.  The implementation is 
in Gadgets modules but parallel implementation in plain Texts 
should be possible.

[ An amateur can use an Oberon system for years and still find 
an unknown and useful feature.  Amazing! ]
