• Entries can reference two runs of Options with zero to fifteen options each in order to reference additional information.
Entries可以引用两个Option Run，每个option run有0到15个Option，以便引用附加信息。
• Note 注意 :
Entries support two option runs to allow referencing the same Options by different Entries. With a single option run, sharing Endpoint Options while having different Configuration Options per Entry would not have work efficiently.
Entry支持两个option run，以允许通过不同的entry引用相同的option。 使用单个option run时，共享endpoint option，同时为每个entry配置不同的Configuration Option将无法高效工作。

first option run以Index 1st option引用的option开始，并引用0到15个option。

first option run引用的option数量由字段# of opt 1 确定。
• The second option run starts with the option referenced by the field Index 2nd options and references zero to fifteen options.
Second option run以Index 2nd option引用的option开始，并引用0到15个option。
• The number of options referenced by the second option run is determined by the field # of opt 2.
Second option run引用的option数量由字段# of opt 2 确定。
