The component definition area follows the key definition area.
It contains a definition for each key component. Each key consists of one component, unless defined as a split key, when each component of the key requires its own component definition.
The component definitions define the position and length of the key component.
For numeric keys, you can use the component definition Area to specify the numeric type. You can then use the IXNUMKEY Compiler directive to specify that keys are ordered according to numeric type (the default situation is that keys are ordered according to their alphanumeric value).
