2.3.3.7 User-defined result variables
Dialog window: Formula editor ▶ Variables
User-defined result variables are generated for the user-defined results
defined by the user in the method. A basic distinction is made between
single results and multiple results.
A single result is an individual numerical value which is calculated
according to a specified formula.
In the case of a multiple result, a formula is specified with which a result
is calculated in the same way for each substance.
