Question: Function readdata, help

Hey

I was trying to use the command readdata to read a *.txt file in which I saved the results of some calculations that I obtained with a program that I wrote in C language.

I'm organizing the data in columns on the *.txt file. For example:

1.00         2.00         3.00
2.00         4.00         6.00
3.00         6.00         9.00
4.00         8.00         12.00
5.00         10.00         15.00
6.00         12.00         18.00
7.00         14.00         21.00
8.00         16.00         24.00
9.00         18.00         27.00
10.00         20.00         30.00
 

Each column represent a value of some thing in the problem that I'm solving: Time, Temperature and Position, for example.

I can read the file with maple, but I would like to know how can I select which column maple should read. I know tha to read the first column the command is the following:

> readdata("location of the file", [float]);

To read the first two column:

> readdata("location of the file", [float,float]);    or   > readdata("location of the file", float,2); and so on...

But how can I make maple read just the second of the third column?

regards..
