WINDOWS BATCH FILE - SEARCH, COPY, APPEND, call other batch file

First Question:
After appending information to a file.
how do you add a Character return at end of line.
instead of having all the information on one line.


Here's my example of what it is i'm going to build...

Begin
Set FTPVALUE = false
search for Source in immediate directory Source FILE1(*.PRC)
If SOURCE FILE FOUND THEN
Open SourceFile1
Open Target
IF line 1 inside sourcefile1 <> EOF.
Copy SourceFile1 into Target
Set FTPVALUE = True
If active line @ EOF then
Move SourceFile into Archive Folder
end if
end if
end if

Call search for Source

If Search for Source = Empty then
IF FTPVALUE = True then
Call FTP Application batch file.
end if
end if

End of Build Target
