Q: What's wrong with the form 'Parse a x[i] b'
line = 'something ; something_else'
item = ''
Loop n = 1 By 1 While line <> ''
Parse line item[n] ';' line -- indexed string
End
Loop i=1 to n-1
Say item[i]
End

-- ===============================
Following works:
line = 'something ; something_else'
item = ''
Loop n = 1 By 1 While line <> ''
Parse line head ';' line -- no indexed string
item[n] = head
End
Loop i=1 to n-1
Say item[i]
End
