See the procedure "Move" in package Ada.Strings.Fixed.

     Move("abc1020", String_10, Justify => Right);
     Move("abc", String_10, Justify => Right);
     Move("4", String_10, Justify => Right);
     Move("1234567uui", String_10, Justify => Right);

(Move also has other parameters for what pad character to use, and what 
to do if the source string is longer than the target.)

Can you tell me any site where i can find a list of all standard packages with 
all procedures and functions listed - with 3 words of explenation?

Yes. The RM. Online at various places, e.g. adaic.org

The list of packages is the front of Annex A. The three words of 
explanation for subprograms are the declarations themselves.

Inside the RM of course:

It would be nice to have a good explanation of each routine of each unit in 
the standard library described in Annex A.

I use the information that is in the RM as much as I can, but often find 
that questions go unanswered.  Often resulting in writing small test 
programs or looking at GNAT source files to try to figure out what a routine 
does or how to use it.

It seems like the Wiki would be an ideal place to elaborate on each of the 
functions/procedures and their use.

Any chance the RM could be converted to Wiki form so that explanations could 
be added where needed?

Yes indeed.

The difference between a reference manual and a tutorial. That's what the
wiki pages have been started for.

We are working on it. But there is so much Ada to describe and so little
time to do it. Help is allways welcome.

Currently we just link to the RM in our descriptions.

There is Ada code that generates the actual RM in various formats from
a Scheme-like markup language. I added a package that outputs TeXInfo
source. It wasn't hard; a few weekend's work.

There is already a module that outputs HTML. I assume Wiki format is
based on HTML.

So yes, it would be quite feasible to write an Ada package for the RM
generator that outputs an initial Wiki.

I'm not interested in actually doing that, but I'd be glad to help
someone get started.

It would be best to wait until the Ada 2006 RM is released; then we'll
have a stable Scheme and Ada code base to work from. That should be
later this year or early next year. However, if someone is inspired
now, I can give you the Ada 95 RM sources.

subtype String_10 is String (1 .. 10);

function To_10 (S : String) return String_10 is
    -- null;
begin -- To_10
    if S'Length >= 10 then
       return S (S'First .. S'First + 9);
    else
       return String'(1 .. 10 - S'Length => ' ') & S;
    end if;
end To_10;
