Hi,

I have an ASCII text file that contains data in a nice tabular form,

0 28660 1827.1 72.7705 -158.8828 3388.0 22.3846 10.8545
1 28661 1827.7 72.7701 -158.8752 3391.0 21.1213 10.6029
2 28662 1828.3 72.7698 -158.8677 3394.0 19.8743 10.3546
.
.
.

I want to read them all and save into an array: data[8, numberOfLines]. But
I don't know numberOfLines in the file before hand. What is the most efficient
way to find that out?

On UNIX, I can pass number of lines information back from wc command. Of
course the same code won't work a on Mac. Please help.

many thanks
