in 8.27 or later;
p_web.ntWizOption(loc:procedure,'saveOk',net:AvailableIfLastTab)
the second parameter is fixed, and case sensitive. The 3rd parameter is one of
net:NotAvailable Equate(-1)
net:Available Equate(1)
net:AvailableIfLastTab Equate(0)
In 8.26 the code is slightly less generic;
p_web.ntWizOption('fWizard','saveOk',-1)
where
'fWizard' is the name of the procedure (case sensitive)
and you use the number, not equate name for the 3rd parameter.
