I am helping someone in writing this ADA program for his class. I tried
to read from the book to how to read a STRING from a text file, but I
could not find anythng, that is the only place I am stuck. The Data file
is something like this.

The programm goes like this. Only place I am stuck is how to read in the 
STRING from above given DATA file.

with Text_IO;

procedure Test_Average is

-- This program finds the weighted average of three test scores

I will really appreciate it.

Thanks in ADVANCE!!!!!!!!!!!!!!!!!!!!!!!!!!
