प्लगइन समय की एक अवधि के लिए कोड निष्पादित कर सकते हैं, और यह कुछ सरल संचालन कर सकते हैं, जैसे किआइसबर्ग आदेश, लंबित आदेश, आदेश रद्द करनाऔरआदेश की गणना. उसी के रूप मेंडिबगिंग उपकरण, यह उपयोग करता हैreturn
परिणामों को वापस करने के लिए, और यह भी सीधे चार्ट और तालिकाओं को वापस कर सकते हैं.
यहाँ कुछ उदाहरण दिए गए हैं, और अन्य कार्यों को आप स्वयं से पता लगा सकते हैं।
