How Quantum reads data
To process the answered questionnaire, the information in the questionnaire must be read into the computer to a location where Quantum can access it. This is done by reading the data into the data variable array called C which is supplied automatically with every Quantum run. You can then access this data by addressing this array.
Different types of records are read into the C array in different ways.
