This string property can be used to label what its parent script line does. For example, in an Insert, the Label may be "Notes Page Every Month" or "Re-Order Form at End of August".
Depending on the script line, the Label text may also appear in the scripts editor.
Generally you should set a Label for insert scriptlines, since they usually need some explaining. Otherwise it is usually best to set Labels only when something out of the ordinary is going on.
In the case of PlaceHolder script lines, the value of the Label property is displayed in the generated page, as shown below.
In addition, you can include global tokens in the Label property.
This is useful to be able to apply year and reference/SKU information to PlaceHolder pages, using a Global Sara such as the one below.
The FIND text can be a token but it can also be any text that you wish. The CHANGE side can be a combination of the global tokens allowed in Global Saras as well as any plain text.
