.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function tests if the argument
.arg c
is a lowercase double-byte character.
These are any characters for which the following expression is true:
.millust begin
0x8281 <= c <= 0x829A
.millust end
.np
These are double-byte codes for the characters 'a' to 'z'.
.desc end
.return begin
The &func function returns zero if the argument is not a lowercase double-byte
character;
otherwise, a non-zero value is returned.
