.ixfunc2 '&CharTest' &func
.funcend
.desc begin
The &func function tests if the argument
.arg c
is a double-byte character equivalent to the single-byte decimal digit
characters "0" to "9".
A double-byte decimal digit character is any character for which the
following expression is true:
.millust begin
0x824F <= c <= 0x8258
.millust end
.desc end
.return begin
The &func function returns zero if the argument is not a double-byte decimal
digit character;
otherwise, a non-zero value is returned.
