.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function converts a double-byte lowercase character to an
equivalent double-byte uppercase character.
A double-byte lowercase character is any character for which the
following expression is true:
.millust begin
0x8281 <= c <= 0x829A
.millust end
.desc end
.return begin
The &func function returns the argument value if the argument is not a
double-byte lowercase character;
otherwise, the equivalent uppercase character is returned.
