[amibroker] AFL+JS problem

["black_marubozu" <bromba@xxxxxxxxxxxx>]

hello,

could you exlpain to me the dependencies between AFL/JS variables, their accessibility and visibility? I have two functions. the first one works fine as I expect, the second doesn't. what's wrong with the latter one?

TIA,
BM

//first function
EnableScript("jscript");
<%
function fjsDoArray( jsStr ) {
  jsStr += "postfix";
  AFL(jsStr) = [];
  AFL(jsStr) = AFL("Low");
}
%>
objScript=GetScriptObject();
objScript.fjsDoArray("name");
Plot(namepostfix, "namepost", colorRed);

//second function
EnableScript("jscript");
function fDoArray( aflStr ) {
  local str;
        str = aflStr;
<%
  var jsStr = AFL("str") + "postfix";
  AFL(jsStr) = new Array();
%>
}
fDoArray("name");
Plot(namepostfix, "namepost", colorRed);
