How to clear an array variable

[waynecd]

Once the ALengths array is run in the bInit routine it is no longer needed.

How do I delete the array to release resources?

This is just a simple example.

Thanks

wayne

debugClear();
function preMain(){
    setPriceStudy(true);
}
var bInit = false; 
var vFontColor9 = Color.red;
var vFontColor13 = Color.blue;
var vFontColor56 = Color.green;
var ALengths = new Array("9","13","56");
var PlotArray = new Array();

function main(){
   if ( bInit == false ) { 
        for (i=0; i<=ALengths.length-1; i++){
            var TempFColor = "vFontColor" + ALengths[i]   
            debugPrintln(i + " - " + TempFColor);
            setDefaultBarFgColor(eval(TempFColor), i);
            var TempEMA = "Study" + ALengths[i] + " = ema(" + ALengths[i] + ")";
            eval(TempEMA)
            TempEMASeries = "Study" + ALengths[i] + " = getSeries(" + "Study" + ALengths[i] + ")";
            eval(TempEMASeries);
            PlotArray.push(eval("Study" + ALengths[i]));
        }
        bInit = true;
    }
 return (PlotArray);   
}

Hi Wayne,

Set the global variable equal to null. Better yet, do not make it a global variable, rather, make it a local variable inside your bInit conditional. It will automatically be garbage collected.

Hi Steve,

For the bInit example I'll use a local variable. For those whithin Main or support functions I'll set them to null.

As usual you go one step further than asked.

Thanks.
