Define Inline Expression

You can use the inline expression in the definition of a simple diagnosis instead of defining a compound variable and then using that variable in the diagnosis.

1. Click the Expression.
   
2. Define the variable and expression.
   
   1. Select the variable that needs to be referenced in the expression.
   2. Click the icon to select the definition expression of the variable.
      

      Note: You can call a built-in function or do a simple math operation (+, -, *, and /), such as $var1 + $var2.

3. View the defined expression in the diagnosis.
