eckstein@bean.ISD.Luftfahrt.Uni-Stuttgart.DE (Knut Eckstein) asked the
same question, and received no answer.

Here 'tis:  #539A0h SYSEVAL (for ROM versions A through E).  This
toggles the lower-case flag.  Note well: the lower-case flag is reset
automatically every time the command line is executed, regardless of
whether alpha mode was on or not.  So to use this SYSEVAL effectively,
it must immediately preceed the INPUT, as in the following example:

%%HP: T(3)A(D)F(.);
\<< # 539A0h SYSEVAL "lowercase:" { \Ga } INPUT
                     "UPPERCASE:" { \Ga } INPUT
\>>

Try it; the keys pressed the first time will automatically be in
lowercase, but the second time in uppercase like usual.
