I'm trying to get the newline mode to work with PBread
but I am having no luck. in IM it states:

"Note: Advanced programmers: Bit 7 of ioPosmode is the newline flag;
it's set if read operations should terminate at a newline character. The
ASCII code of the newline character is specified in the high-order byte of
ioPosMode. If the newline flag is set, the data will be read, one byte at a
time unitl the newline character is encountered, ioReqCount bytes have been 
read, or the end-of-file is reached."

This is what I tried :

posmode := $0D00;          {set the highorder byte to CR }
 BitSet(@PosMode, 0);      {set bit 7 }
 while error = noerr do
  begin
   with myPB do
    begin
     ioCompletion := nil;
     ioRefNum := refnum;
     ioBuffer := buf^;
     ioReqCount := 100;       {set to 100 because CR is before 100 bytes }
     ioPosMode := PosMode;    {in the test file }
    end;

   error := PBRead(@mypb, false);

 
After the read, myPB.ioActCount = 100 and buf is filled with 100 bytes
of data. 

What the hell am I doing wrong?

Thanks
