Q: Parse a line?

Q: Parse a line?

[Kevin R.J. Ellwood]

Hello,

I am fairly new to Ada and the book that I have didn't help with
this question.  What I need to do is to read a line in as a string
and then read some integer values from it.  In fortran I could
use an internal read statement to read from the string. Can anyone 
give a simple way of doing this in Ada?

Thanks
Kevin

Kevin:

Just in case you haven't received a dozen answers for this already...

Check out LRM 14.3.8, par 17..23 if you're interested in real
numbers.

Here's an example:

with TEXT_IO ;
procedure FU is

    S   : constant STRING   := "   3.14159   " ;
    F   : FLOAT             := 0.0 ;
    L   : INTEGER           := 0 ;

    package
        BAR
    is new
        TEXT_IO.FLOAT_IO (
            NUM     => FLOAT ) ;
    use BAR ;

begin
    BAR.GET (
        FROM    => S,
        ITEM    => F,
        LAST    => L ) ;
end FU ;

Good luck with it.

Pax,
Marin

Try the Integer_IO.Get that reads from a String, or use 'Image.
