Q. How does variables in Plugins work?

A. Upto STU ver. R19.0917, it has three (3) variable schemes. They are 1)predefined global variables, 2)user defined variables, and 3)plugin defined variables. In the plugin, only when you desire a CSV to stored as a variable, you must use the plugin defined variable. In this case, the values are stored in multi dimesional CSV format and you can acces data by a notation as {{group name.header name(row number)}}. In this case, the header name comes from the first row of the data (row = 0). If the first row contains data check box has been checked the header name are automatically assigned to A,B,C,D, as in Excel sheet (in uppercase alphabets). The row number must be an integer.
