The answer Laurent Roseenfeld gave you works for read and readchars as well.
Save the following lines in a file and run it (try and change .read into
.readchars too); it will output a series of 10-byte long Buf[uint8]s,
until it reaches the end of file.
#!/usr/bin/env perl6
given $*PROGRAM-NAME.IO.open {
while my $bytes = .read: 10 {
$bytes.say;
}
}

Please expand the question to include `read` and `readchars`.

Hi Frenando,
Thank you for the help!
I am not getting anywhere with `.lines`. Read the whole thing in the
first line.
$ p6 'my $fh=open "/home/linuxutil/WhoIsMySub.pl6", :r; while my $f =
$fh.lines { say "$f\n"}; $fh.close;'
#!/usr/bin/env perl6 sub f() { put &?ROUTINE.gist; }; sub abc () {
say "This subroutine's ID is ", f; print "\n"; &?ROUTINE.gist
~~ m/' '(.*?)' '\(/; my $SubName = $0; say "This subroutine is
called $SubName"; } abc;
-T
