postponed processing

postponed processing

[Henning Hraban Ramm]

Me again...
I'd like to define an address layer in my environment:

--- start env --

\definelayer[senderlayer]
	[x=0mm, y=0mm, width=\paperwidth, height=\paperheight]

\def\Sender#1#2#3{\setvalue{SenderKey#1}{#2}\setvalue{SenderVal#1}{#3}}
\def\GetSenderLine#1{\bTR\bTD\doiftextelse{\getvalue{SenderKey#1}}%
	{\getvalue{SenderKey#1}:}{}\eTD\bTD\getvalue{SenderVal#1}\eTD\eTR}

\setlayerframed[senderlayer]
	[%corner={right}, location={left,bottom},
	x=\dimexpr(\getvalue{LogoHOffset}-\bleed), %\getvalue{LogoHOffset},
	y=\getvalue{LogoHeight}] % \dimexpr(\getvalue{LogoHeight}+\topspace)
	[height=46mm, width=\dimexpr(\getvalue{SenderKeyWidth}+\getvalue 
{SenderValueWidth}),
	frame=off, offset=none, align={left,top}]{%
	\setupTABLE[frame=off]
	\setupTABLE[x][1][width=\getvalue{SenderKeyWidth}, align=left, style= 
{\keystyle\strut}]
	\setupTABLE[x][2][width=\getvalue{SenderValueWidth}, align=right,  
style={\valstyle\strut}]
	\bTABLE
	\dostepwiserecurse{1}{9}{1}{% count from 1 to 9, step 1
		\expanded{\GetSenderLine{\recurselevel}}
	}
	\eTABLE
}

\def\EnableSender{\setupbackgrounds[rightpage][page]
	[background={\currentvalue, senderlayer}]}

--- stop env ---

and use that later in a product/component:

--- start text ---

\Sender{1}{Name}{Hraban}
\Sender{2}{Web}{www.fiee.net}

\EnableSender

--- stop text ---

Of course it doesn't work, because the Sender values aren't set via  
typesetting the address in the environment, and \x1c\currentvalue in  
\EnableSender hasn't the right value either.

Holger solves this in his letter style (wiki) via setups.
Is that the best approach?
How else could I postpone the senderlayer processing?
(I guess it would work with some expansion magic, but I'd like to  
stay at ConTeXt's surface as much as possible.)

by making it a setup (best use variables instead of #1's etc) and 
process that setup later on

see m-letter and m-corresp for how we do things at pragma

I'm getting used to setups - looking at Holger's code I thought they  
were complicated, but it's only his code...

I don't understand how and where I should use \variables instead of  
#parameters?

I'd love to, but they aren't in the distribution.
