Defining Multiple Symbols

Defining Multiple Symbols

You can define symbols based on another symbol that you define in the same rule or a symbol that you defined in a previous rule.
To define a symbol based on another symbol in the same rule, use the expression
\(Symbol_name)
to call the symbol value in a subsequent row.
The following image shows a rule that defines two symbols: The first row the Symbol Definition list has Symbol Name set to A and Symbol Value set to Value1. The second row has Symbol Name set to B and Symbol Value set to \(A).
In the image, the value of symbol A is set to Value1. Because symbol B calls the value of symbol A, the value of symbol B is also set to Value1.
However, if you reverse the order of the rows in the rule, symbol A is not defined when the value of symbol B is set, and symbol B has a null value.
