 It comes up in the context of the "append" command. And it means
 that you can't append a series whose values represent strings to a
 regular numeric series, or vice versa. (That is, "lengthwise",
 in adding observations to an existing dataset. It's OK to add a
 string-valued series as a new series, to a dataset that currently
 contains only numeric series, provided the newly added series is of
 a suitable length.)
 This is a newly added error message, stemming from a revision of
 "append", which was not doing the right thing with string-valued
 series in general. 
Thanks for the clarification, Allin!
Best,
