Read some bytes from a file

The code below reads a byte at a time from a file until the marker reaches 15 and then stops.

Code

local(my_file) = file('/rhino/test.txt')
handle => { #my_file->close }
#my_file->openRead
while(true) => {^
    if(#my_file->marker > 14) => {^
        loop_abort
    ^}
    #my_file->readSomeBytes(1)
^}

Result

"Great Scott!"
