How to get a Array with Call();

[shogun]

When using call(); to retrieve data from another efs i am finding the only way i can retrieve more than one piece of data is to use GlobalValue, is this a sound practice or is there a better way to send a Array and retrieve it see below code the top one is the efs that is being called,

the return new Array(aa3,axp3,ba3,c3,cat3,dd3); data is being received by the calling efs in the correct order but it does not read it as a Array, where as if the data is sent by GlobalValues it is received as it should be,

if using GlobalValue to transmit the data is a sound practice what is the limitation on it , could i call 30 sets of data through 5 efs studies.

if(cat1 >= cat2){
cat3 = 1;
}else{
cat3 = 2;
}
if(dd1 >= dd2){
dd3 = 1;
}else{
dd3 = 2;
}

setGlobalValue("aa_aa",aa3);
setGlobalValue("axp_axp",axp3);
setGlobalValue("ba_ba",ba3);
setGlobalValue("c_c",c3);
setGlobalValue("cat_cat",cat3);
setGlobalValue("dd_dd",dd3);

//debugPrintln(test," test = ");
//debugPrintln(aa3,"  ",axp3,"  ",ba3,"  ",c3,"  ",cat3,"  ",dd3);


return new Array(aa3,axp3,ba3,c3,cat3,dd3);
} 

var aaa = null;
var aaxp = null;
var aba = null;
var ac = null;
var acat = null;
var add = null;
var test1 = new Array();
var up = null;
var down = null;

function main(){

var test = new Array();
up = 0;
down = 0;

aaa = getGlobalValue("aa_aa");
test.push(aaa);
aaxp = getGlobalValue("axp_axp");
test.push(aaxp);
aba = getGlobalValue("ba_ba");
test.push(aba);
ac = getGlobalValue("c_c");
test.push(ac);
acat = getGlobalValue("cat_cat");
test.push(acat);
add = getGlobalValue("dd_dd");
test.push(add);

//debugPrintln(aaa," aaa ",aaxp," aaxp ",aba," aba ",ac," ac ",acat," acat ",add," add ");

test1 = call("EFS2 Test Symbols.efs");
debugPrintln(test[0]);
//debugPrintln(test1[0]);
result(test);
debugPrintln(up," up = ",down," down = ");

return;
}

function result(ntest){

for(i=0;i<6;i++){
  if(ntest[i]==1){
  up ++;
  }else{
  down ++;
  }
 }
return;
}

Hello Shogun,

The key to using call() is to perform a null check immediately after and exit the formula when the return from call is null. The setGlobalValue/getGobalValue routine will make it difficult for you to synch up the historical values. Try something along these lines, which is EFS1 logic.

var up = null;
var down = null;

function main(){

    var test = new Array();
    up = 0;
    down = 0;    
    
    var test1 = call("EFS2 Test Symbols.efs");
    if (test1 == null) return;
    
    result(test1);
    debugPrintln(up," up = ",down," down = ");
    
    return;
}

function result(ntest){    
    for(i=0;i<6;i++){
        if(ntest[i]==1){
            up++;
        }else{
            down++;
        }
    }
    return;
}

I would like to add, that you should be able to get rid of using call() and callFunction() with EFS2.

I'm not sure of your exact implementation, but IMO it might be easier to look into using efs() or efsInternal() or perhaps the EFS FunctionLibrary to do what you need to do ?
