.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function converts a double-byte uppercase character to an
equivalent double-byte lowercase character.
A double-byte uppercase character is any character for which the
following expression is true:
.millust begin
0x8260 <= c <= 0x8279
.millust end
.desc end
.return begin
The &func function returns the argument value if the argument is not a
double-byte uppercase character;
otherwise, the equivalent lowercase character is returned.
