reading a column from a file

[Gary Wessle]

Hi

I have a file with data like
location pressure temp
str       floot    floot

I need to read pressure and temp in 2 different variables so that I
can plot them as lines. is there a package which reads from file with
a given formate and returns desired  variables? or I need to open,
while not EOF read, parse, build list, return?

thanks
