Hello Kat,

Wouldn't be a better way to do the job this code?:

include file.e
include get.e
integer fn
fn = open("file.txt","rb")
integer char
sequence result
result = {}
while 1 do
    char = getc(fn)
    if char = -1 then exit -- EOF
    eslif char = 0  then -- ignore
    else result &= char -- append to the result
    end if
end while
close(fn)
