Madhusudan ,

The following uses Export and Import from Mathematica 4.0

Make table

data = Table[Random[Integer, {0, 9}], {5}, {3}]

{{8, 9, 3}, {6, 2, 0}, {8, 3, 5}, {0, 6, 6}, {3, 8, 3}}

Export it to the file "temp"

Export["temp", data, "Table" ];

This is what is in the file

!! "temp"

8   9   3
6   2   0
8   3   5
0   6   6
3   8   3

Import the file

Import["temp", "Table" ]

{{8, 9, 3}, {6, 2, 0}, {8, 3, 5}, {0, 6, 6}, {3, 8, 3}}

With Mathematica 3.0 we can use

ReadList["temp", Number, RecordLists -> True ]

{{8, 9, 3}, {6, 2, 0}, {8, 3, 5}, {0, 6, 6}, {3, 8, 3}}
