  • variable declaratioin inside of preMain()

    Does it matter if I make var AFPArray = new Array() a local variable within preMain?

    I believe it would reduce the load on the global namespace (if that is where globals are kept).

    I don't want to miss something important since I have always seen it outside of preMain.

    In testing some menu options I found that declaring var AFPArray = new Array() just after the function preMain() has the same effect as making it global outside of preMain as the sample efs below shows:

    PHP Code:
    debugClear();
    function 
    preMain() {
        var 
    aFPArray = new Array();
        var 
    x=0;
        
    aFPArray[x] = new FunctionParameter("vSymbol"FunctionParameter.STRING);
        
    with(aFPArray[x++]){
            
    addOption("$TRIN");
            
    addOption("$ADD");
            
    addOption("$TICK");
            
    addOption("None");
            
    setDefault("$ADD");
        }
        
    aFPArray[x] = new FunctionParameter("Interval"FunctionParameter.STRING);
        
    with(aFPArray[x++]){
            
    setName"Price Interval" );
            
    addOption("D");
            
    addOption("W");
            
    addOption("M");
            
    setDefault"D" ); 
        }
    }
    var 
    bInit false;
    function 
    main(vSymbol,Interval0){
        if(!
    bInit){
            
    debugPrintln("25S: " vSymbol ", I: " Interval0);
            
    fTest(26,vSymbol,Interval0);
            
    bInit true;
        }
        if(
    getCurrentBarIndex() == 0){
            
    debugPrintln("29S:" vSymbol ", I: " Interval0);
            
    fTest(31,vSymbol,Interval0);
        }
    }
    var 
    fInit false;
    function 
    fTest(n,fSymbol,fInterval0){
        if(!
    fInit){
            
    debugPrintln(": 37S: " fSymbol ", I: " fInterval0);
            
    fInit true;
        }
        if(
    getCurrentBarIndex() == 0){
                    
    debugPrintln(": 41S:" fSymbol ", I: " fInterval0);
        }
