Use '''[https://www.stata.com/help.cgi?f_strupper strupper]''' and '''strlower''' to change case of ASCII characters. Use '''[https://www.stata.com/help.cgi?f_ustrupper ustrupper]''' and '''ustrlower''' to change case of all Unicode letters.
<lang stata>. scalar s="alphaBETA"
. di strupper(s)
ALPHABETA
. di strlower(s)
alphabeta</lang>
Notice there may be some difficulties with Unicode characters. In the following, the uppercase '''[https://en.wikipedia.org/wiki/Sigma sigma]''' is correctly converted back to the lowercase variant, but the '''[https://en.wikipedia.org/wiki/Iota_subscript]''' is not.
<lang stata>. scalar a="Ἐν ἀρχῇ ἐποίησεν ὁ θεὸς τὸν οὐρανὸν καὶ τὴν γῆν"
