The following examples show the command that
produces the TURF output, the TURF report and
the REACH.RESULTS file. The TURF commands can
be entered manually or generated from the pull
down menus. Examples using TURF from the menus can
be found in the manual "P-STAT:An Introductory Guide
for Windows Users".
