Thanks for your response.
I am soooo sorry. This is another RTFM for me.
I was thinking that "executeCommand" method would be doing some lexical
stuff. As it turns out, the section on the "batch" jess function fully
describes the situation:
>From the jess functions section:
Note: the argument must follow Jess' rules for valid atoms or strings. On
UNIX systems, this presents no particular problems, but Win32 filenames may
need special treatment. In particular: pathnames should use either '\\'
(double backslash) or '/' (forward slash) instead of '\' (single backslash)
as directory separators; and pathnames which include a colon (':') or a
space character (' ') must be enclosed in double quotes.
What is happening is the lexer/parser used by executeCommand needs the
quoted slashes.
I was looking in the wrong place. Sorry.
