I humbly apologise. I can now see that this is a feature and not a bug.

At the MS-DOS prompt when I type:
   type ./b.ex
I get the message:

 G:\MYDOCS~1>type ./b.ex
 The syntax of the command is incorrect.

Then I enter  :
  type "./b.ex" 
and I get ...

 G:\MYDOCS~1>type "./b.ex"
 include .\a.e
 include ..\mydocs~\a.e


So it would seem that DOS accepts either type of 'slash' symbol when it 
is is clearly a part of the file-path string. 

On this basis, it could be argued that Euphoria is not compliant with 
MS-DOS systems. However, I *would *never *say *that, because Euphoria is 
perfect in every way
