Hi Chris,

Depending upon the version (eg 5.0), there's a Help section in "Tour's"
called "Handling data" that should have put you on the right track.

If you haven't gone through section 1 of The Book (eg ection 1.9.8), then
you have missed something.

Try:
	xdat = Table[{x, Sin[x]}, {x, -Pi, Pi, Pi/32}];
	Export["test.txt", N[xdat], "Table"]

	idat = Import["test.txt", "Table"];
	ListPlot[idat];

Then look further at each of these options (eg. ?Table, ?Export, ?Import,
?ListPlot).

Regards,

Dave.
