That should be:

  IF ch = 0DX ....

with a leading zero to signify that it is a numeric value to distinguish
it from an identifier.


1. 0DX (13 decimal) is actually an ASCII CR (carriage return) character.
An ASCII LF (line-feed character) is 0AX (10 decimal). 

2. Conventionally on Unix systems end-of-line is just LF and on MS-DOS
heritage systems end-of-line is a CR-LF pair. 

3. I don't know about Java but in C, '\n' is an LF character.
