for some reason my last reply got screwed up and didn't go tot he list.
for those interested, there's a little perl script i have that fixes this
problem.
http://comp20.eecs.tufts.edu/jperlmut/
"clean.pl"
dl the instructions too. it's all there. that is from the cross enrollment
course i took. i'm suprised they haven't taken it down.
anyway, a lot of students at deis write progs one their windows boxes and
the ftp them to their cs account. one of my friends wrote the script to get
rid of those pesky ^M characters without doing the manual work.

If you have textutils installed, you can simply do
tr -d "\r" < input_file > output_file
This removes all the occurrences of ^M in the input file.
Alternativley,
tr "\r" " " < input_file > output_file
substitues all the ^M with spaces.

Yes, this is exactly the problem you had before.
^M is ASCII 13, representing carriage return (CR); hence you could
replace the single character constant '^M' with any of the following:
13
'\x0d' (backslash x zero d: 0d is hexadecimal for 13)
'\r'
(or the octal string escape represntation, or hex or octal immediates,
etc.)
The last is a special C-escape for CR and perhaps the most useful
representation since it describes the intended meaning here. (On the
other hand, this might not be appropriate if you're specifically dealing
with PC text files guaranteed to be 13-10 and the host system's CR might
not be 13 or something - I guess it's a style call.)
If you have ^M in the middle of a string then you should replace it with
a string constant escape such the latter two, \x0d or \r.

Some time back I mentioned a problem I had with the ^M character (see below).
It so happens that I need to be able to replace every ^M in my resultant file
with a " " charachter.
GNU isn't happy with ^M. Is there a way to define ^M in another way?
Thanks in advance

Embedding a character 13 into the source is horrible and, as it happens,
is causing this problem. (I also don't like the next line: there's no
point dereferencing a constant string just for a space! This isn't a
really bug, though - just style.)
Try:
while((pChar=strchr(Uwel_notes1.str,'\r'))!=NULL)
*(pChar) = ' ';
The problem was that the compiler was interpreting the ^M as a line
break and not a character constant. It was trying to compile:
while((pChar=strchr(Uwel_notes1.str,'
'))!=NULL)
and single-quoted constants may not cross line boundaries.
