Within a Mathematica string, commas do not need escaping. In:= stmp = OpenWrite["test.txt"] Out= OutputStream[test.txt, 3] In:= WriteString[stmp, "before, after"] In:= Close[stmp] Out= test.txt In:= !! test.txt before, after Hence, you should be able to replace "\t" with ",". If you use Mathematica 4.1, the kernel also supports export to CSV format. -- P.J. Hinton User Interface Programmer paulh at wolfram.com Wolfram Research, Inc.
