start: ENUM= one
end:   ENUM= one   | index:          1 | value: one   | base: A | isfirst: .T. | islast: .F.
start: ENUM= two
end:   ENUM= TWO   | index:          2 | value: TWO   | base: A | isfirst: .F. | islast: .F.
start: ENUM= three
end:   ENUM= three | index:          3 | value: three | base: A | isfirst: .F. | islast: .T.
after loop ENUM= b
after loop: a[1]= one   a[2]= TWO   a[3]= three
