Hi Don,

The accents got in there because the user could have typed them
going by the rule that they have to use a delimiter to separate
paths, as in:

  'c:\MyDir\My'File' 'd:\MyDir2\My'File2'

which as you can see wont work because the program wont know which
accent to end the path(s) on.

Keep in mind we could also have this:

  'c:\MyDir\My'File' -' 'd:\MyDir2\My'File2' -'''

which would be strange, but still possible.

What this means is that we have to parse the paths and any arguments
to each path that may be present.

I have other (future) plans to have the UI parse paths BEFORE any
delimiters are needed (so the program can choose perhaps) but
this part of the functionality will still remain intact...ie the
user has the ability to enter the path typed as they see fit,
with delimiters.

Another possibility when there are spaces in the path:

  "c:\MyDir\My 'Other' File" -'a'

Where does the user put the accents in this example, and when a second
path (and arg) follows this one?



Take care,
Al
