problem with functions

[Bartje]

Who can help me out with the following problem. Here is a simplified version of my code.

//global
var s

function preMain() {
...
}

function main() {
...
if (condition w) {
debugPrintln("test 1")}
...
if (condition x) {...}
else {s=fSample();
debugPrintln("test 2" + s)}
}
...
return ...;
}

function fSample() {
var i=-1;
if (condition y) {
i=1;
while (condition z) {...}
...
}
return i;
}

I discovered in the formula output window, that in the case of failing condition y, function fSample is called for twice, right after each other (1 time too much!--> error 1). If condition y is met, s is given the value i, but the debugPrintln("test 2" +s) is never called for. The program seems to jump right to debugPrintln("test 1") again (--> error 2). And that without any loops, which could cause this, being present!

Could someone please explain me what's happening here?

Hello Bart,

Welcome to the community. Take a look at the following setup of your example.

function preMain() {
    setStudyTitle("test");
    //setPriceStudy(true);
    setShowCursorLabel(false);

}

//global
var s

debugClear();

function main() {
    var condition_w = true;
    var condition_x = false;
    //...
    if (condition_w) {
        debugPrintln("test 1")
    }
    //...
    if (condition_x) {
        //...
    } else {
        s = fSample();
        debugPrintln("test 2: " + s)
    }
    //...
    return //...;
}

function fSample() {
    var condition_y = true;
    var condition_z = false; // don't set this to true!
    
    var i = -1;
    if (condition_y) {
        i = 1;
        while (condition_z) {
            //...
        }
        //...
    }
    debugPrintln("fSample executed");
    return i;
} 

Based on this code, I'm only seeing fSample() getting called once per execution of the formula when condition_y is false. Do you have any other calls to fSample() somewhere else in your code?

Setting condition_y to true will set i = 1. In main(), the "test 2:" debugPrintln() statement will only be called if condition_x is false. Add a debugPrintln() statement just above "if (condition_x)" and check to make sure it is false.

Jason,

Thanks for your advice. I checked my code again; 1 of my conditions was not properly formulated. It took me a while to find it, but it finally works!

Bart
