FFIND is an internal command. The internal commands which duplicate some
CMD.EXE / COMMAND.COM feature often do return an ERRORLEVEL. However, it is
quite possible that FFIND never sets the errorlevel.

Try testing the exit code designed for internal commands, _?. It may give
you the information you desire. However, often the only information from the
exit code itself is whether or not the command execution ran into trouble,
and you need to capture the command output itself.

BTW, if you are using FFIND just to determine whether or not any files with
attribute A are present in a single directory, you can use the @FILES[]
function:

if %@files[*.*,A] gt 0 goto HAVE_NEW

If you need to know about a whole directory tree, you can use the DIR
command, with option /U2. You may need to pipe it to TAIL to strip
everything but the last line, and you can use the @EXECSTR function to put
the result into a variable.

Somethins like this may work (UNTESTED):

set new=%@word[" ",4,%@execstr[(dir/s/a:a-d/u2/k | tail /n2 )]]

Note the use of a command group as the parameter to @EXECSTR - it is often
critical.
