Ok Viktor, I do it.
Now support index & indirect arguments ANSI C99 .-
Local cName := "Bond", cCity := "Tokyo"
? _SPD( "Hi, I'm %01$s from %02$s.", cName, cCity ) // -> "Hi, I'm Bond
from Tokyo"
? _SPD( "Hi, I'm from %02$s, my name is %01$s.", cName, cCity ) // ->
"Hi, I'm from Tokyo, my name is Bond"
? _SPD( "Phi = %2$0*3$.*1$f", 10, (1 + 5**0.5) / 2, 13 ) // -> "Phi =
01.6180339887"
Please, could you update the repository for me, I would be very grateful.
I understand that the provide of the successive versions they make
easier understand the logic.
I think that the better name for the function would be Sprintf() but I
believe that it is not my decision.
Thanks in advance.

This is TO DO, do you want do it?
No thanks, I'm doing enough things with Harbour already,
and I personally don't plan to use _SPD().
My problem is that I have limited time, as we all suppose. :)
Yes, we all have limited time.
Brgds,
Viktor
In my case, the necessity of the function is mount SQL sentences in
the same way that in C with some help.
New functionality or improvements in benefits are welcome: this is
Open Source.
About the name I think it should be the Harbour's community who name,
_SPD is just the name that I have given.
Best regards

Hi Javier,
One more thing (well two).
IMO to make this function more universal and even easier
to use and update (and usable for someone needing it for
translated text formatting), I think it would very
nice if there would be a possibility to specify the
_ordinals_ of those format strings:
cName := "Bond"; cCity := "Tokyo"
_SPD( "Hi, I'm %#01s from %#02s.", cName, cCity ) -> "Hi, I'm Bond
from Tokyo"
_SPD( "Hi, I'm from %#02s, my name is %#01s.", cName, cCity ) ->
"Hi, I'm from Tokyo, my name is Bond"
[ I seem to recall there is a standard way to achieve this
in printf(), but I didn't find any specifics, so I might be
wrong. ]
To bring this to another level - but this is even more
out of scope of this one function -, it would be great
to have something where you can replace _named_ strings:
_FILL( "INSERT INTO stuff ( stuff_ID, stuff_Name ) VALUES (
%stuff_ID%, %stuff_Name% )",;
{ "stuff_ID" => cStuff_ID, "stuff_Name" => cStuff_Name } )
(or something along this line)
This could be useful for a number of purposes. Basically
a light form of template engine. Maybe it would be best
to mimic some existing standards for the format strings.
Brgds,
Viktor
