[stringtemplate-interest] Parallel list iteration over a template

[..... Ollio ......]

Hello Ter

thank you very much for your quick response and your hint. It help me to work out my problem, also I had to slightly modify the suggested term. 
The solution of the problem is attached below. As you can see from the formatting of the rendered output I'm still at the beginning of my learning curve. 

I put some comments directly in the outputgeneration below. Maybe the online documentation concerning parallel list iteration in "Stringtemplate Cheat Sheet" would deserve some more detail information about that matter. I was also doubted because the talk there is about anonymous template (inline code between the curly brackets?) I intended to use a named template instead.


Thanks again

File LPNO_02.js
------------------------------------------------------------------------
{
"list1" : ["A0_A1_A2", "A3"],
"list2" : ["A0 Number, A1 Varchar, A2 varchar", "A3 number"]
}


File LPNO_05.stg
------------------------------------------------------------------------
group LPNO_05;
/* USAGE: stst LPNO_05.main LPNO_02.js -a  
*/
main() ::= <<

<list1:{s | <foo1(ps=s)>}>
-- done 1

<list1:{s | <foo1(s)>}>
-- done 2: implicit parameterpassing acutalparameter s to formal parameter ps works !!
-- this only works with one single parameter
-- all other parameter passing must be done in the acutual template-Call 
-- by explicit assingment of actual to formal parameters
-- order of the parameters passed has no meaning for STRINGTEMPLATE
-- this violated my generativ grammatic experience(*) from PASCAL, MODULA and VBA and 
-- now requires cognitive reprogramming my programmers mind ;-o
-- (*) vgl Noam Chomsky  ;-)

<list1,list2:{s,p | <foo2(ps=s,pp=p)>}>
-- done 3

<list1,list2:{s,p | <foo2(pp=p, ps=s)>}>
-- done 4 with different order in actual parameterlist


<list1,list2:{s,p | <foo2a(s=s,p=p)>}>
-- done 5

>>

foo2(ps,pp) ::=  <<
function SHOW_BY_<ps>(<pp>)
