In a run-in-place system, latency-test requires that you set up the
proper environment variables. The command to do this in a shell is
. scripts/emc-environment
(assuming you are in the top directory of an emc2 checkout; you could
use a full path such as
. /usr/src/emc2.cvs/scripts/emc-environment
or whatever is appropriate on your system).
The suggestion that PATH should contain "." doesn't make much sense to me.

There shouldn't be a connection between putting the value 10.00 in #1
and this extra 10.00" offset you saw. You should be free to use #1 for
any purpose you like in MDI or in part programs. (though variables
#1 through #?? have special meaning in 'O- call' and 'O- sub': they are
used for arguments and local variables)
