Why don't you try it and find out yourself? (It does the same thing as your spawn to "awk".)

> If it is the case then my problem remains unsolved because i want to READ columns from a file without knowing how much column does this file has. Say If I have infinite number of columns And I want to read 100th column how would I do that, shall I need to give 100 parameters in Readcol?? This seems tough to me.

If your data is all numeric then the easiest thing is to use READ_ASCII

output = read_ascii('myfile.dat')

the output array will contain all the data. Then just select the column of the array you want.
