Dynamically derived variables are defined in the metadata only and do not actually exist in the case data. After they have been defined in the metadata, they can be queried just like any other variable, but are calculated “on the fly”.

The following mrScriptBasic examples show how to create these types of dynamically derived variables: numeric, Boolean, and categorical.

The examples use the Museum sample data set, which is installed with the UNICOM Intelligence Developer Documentation Library. The data set consists of two files (museum.mdd and museum.ddf), which by default are in:

If the files are in a different location on your computer, you must edit the code before you run the examples.
