The Line counter is maintained for you by Ada.Text_IO -- the number of
the line jus read is given by Ada.Text_IO.Line (File) - 1

There's good 'ol fashioned Ada.Text_Io.Get_Line.  Create a buffer
of sufficient size.  Call Get_Line to read the file line by line, and
then parse the buffer looking for the particular word (maintaining a
line counter as you go).

If your application is interactive where the user will make multiple
queries, you might be better off reading the entire file into a memory
buffer and then parsing it.  If speed and efficiency are not paramount,
then the first approach will probably suffice.

Does anyone know how a sequential/linear search is created under a txt
file (to find a specific word line by line).  I have an idea how it is
done using an array, but not under a file.  Any ideas?

Thanks.

caution: not for standard_input
function line without parameters defaults to standard_output
