ExpressionBlock Class

For some function, you need multi-statement nested expressions. You need to use the ExpressionBlock class to group these expressions. For example, all the statements inside of a FOR statement should be included in an expression block.

FOR(&Index, 1, PERIOD, 
   SET(&Value, &Value + 1);
   SET(&countPl4, &countPl4 + 4);

Use the following code to create an ExpressionBlock object:

&ExpressionBlock = create ExpressionBlock();
