Consider this a convenience feature that is not 100% conforming to spec. In a fileIn you have to have the period other wise it has no way to tell where statement is ended (which can span multiple lines) > > Thanks everyone, > Gary > > > On Fri, Jan 15, 2021, 12:38 PM Gary Highberger <[email protected]> > wrote: > >> Hi Everybody, >> >> Obviously what programming skills I have are other than Oops :-) >> >> What Oops rule(s) does the following program, autoRun,st, break?
