The Auto-calculate Feature The Auto-calculate Feature The Auto-calculate Feature The Auto-calculate Feature
For list and data variables, the Data/Matrix Editor has an Auto-calculate feature. By
default, Auto-calculate = ON. Therefore, if you make a change that affects a header
definition (or any column referenced in a header definition), all header definitions are
recalculated automatically. For example:
• If you change a header definition, the new definition is applied automatically.
• If column 2’s header is defined as c2=2 ùc1, any change you make in column 1 is
automatically reflected in column 2.
To turn Auto-calculate off and on from the Data/Matrix Editor:
