Please be aware that above is a non-standard file format on *nix which doesn't recognize those <CR> chars. You might need to remove those to get a standard *nix text file; see Aia's proposal.
For exactly your request and your data from post#1, try
Code:
awk '{while (!/\r$/) {getline X; $0 = $0 "," X}} 1' file
1111,FILE, TEST,787
3333,FILE,78,7

The <CR> chars from the input file are still there (as requested) but invisible in the printout.

cr(1)                                                         General Commands Manual                                                        cr(1)

NAME

       cr - converts text files between nix EOL and dos EOL

SYNOPSIS

       cr  - | +  <input file> <output file>

DESCRIPTION

       Text  files,  such  as tle files, that come from a dos source usualy have the ^M symbol at the end of every line. Cr converts files between
       the dos newline format and the normal *nix newline format by stripping the ^M to convert dos to *nix, using the '-' option, or adding ^M to
       a *nix file to create the proper dos file when the '+' option is used.

       Although this extra character is not often a problem, programs like seesat5, which are data driven will encounter parsing problems when the
       extra character is present. It is these problems that cr is intended to repair.

   Options
       - | +  One or the other of these options is required. The '-' option is used to remove ^M from all newlines found in the dos file. The  '+'
              option is used to add ^M to every newline found in a *nix file.

       input file
              Fully delineated path to the input file. As this program is used in the dos environment as well, standard input is not used.

       output file
              Fully delineated path to the output file. As this program is used in the dos environment as well, standart output is not used.

SEE ALSO

       seesat5(1), seesat5(7), SEESAT5.INI(5), tle(5)

BUGS

       Cr  is  not an inteligent program. It methodicaly replaces/removes the offending character when it finds it in the correct context. Newline
       sequences found in contexts other than 'newline' will be replaced/removed just like those found in the proper  context.  Passing  a  binary
       file through cr is not advised, for this reason. Send all inqueries to Dale Scheetz <dwarf@polaris.net>.
