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:
