Just a guess, but I'd say the file I/O functions in your compiler's library
are stripping out all carriage returns.  Atari compilers usually do this to
convert text files from Atari format (Which ends each line with a
carriage-return/line-feed pair) to Unix format (which ends each line with just
a carriage-return) so that programs can be ported from UNIX to the ST more
easily.

You're going to have to disable this conversion by openning the file as a
"binary" file.  With the old Megamax compiler, this is done by beginning the
file mode string with a 'b', as in:

        fp = fopen("STARTREK.PIC", "br");

                                    ^-- Notice the 'b'

Hope that helps.
