To the Mathgroup -- I would like Mathematica to do a simple thing for me. I would like to be able to take a list of pairs, e.g., pairs = {{x1,y1}, {x2,y2},{x3,y3},...{xn,yn}} and write it out to a file in the form x1 y1 x2 y2 x3 y3 ..... xn yn Unfortunately, the closest I have come to this is with OutputForm[TableForm[pairs]] >> file, which gives me the desired result except with an extra carriage return between lines: x1 y1 x2 y2 x3 y3 ..... xn yn (For those of us who think that Mathematica does a less-than-spectacular job in plotting things, writing out {x,y} pairs in the form mentioned above is rather useful, so that they can be plotted by some other program.) Any suggestions would be appreciated. Elegance is not a requirement, although I would prefer something that I can stick in a definition and be done with (e.g., define a new Form such as XYForm[]). Thanks, Chris Myers myers at sbitp.ucsb.edu P.S. To the Moderator: I am on the Mma mailing list as myers at helios.tn.cornell.edu. I have moved and would like my address updated to myers at sbitp.ucsb.edu.
