Update Field events are used to fill or increment the current value of a field by
loading data from the printstream into the specified field. An Update Field event is
added to the text block from which the data is to be extracted.

In the design of an environment, Update field events must be added to a text block
before Data Change events are added.

The printstream data to be used to fill or increment a field is specified in the Update
Field Event dialogue. When extracting the data from the printstream, the options to
‘Update’ a field are Fill and Increment.

• 

A ‘Fill Field’ event will replace the current contents of the field with the
specified data. This becomes the Current Value of the field and replaces any
previous value.

• 

An ‘Increment Field

’ event will add the specified data to the current value

of the field. By specifying a line range it is possible to total a column.

‘Increment’ is normally only possible on Numeric fields.

The Fields function is described in detail in Chapter 5, ‘

Environment Menu’ of this manual and in Chapter 8, ‘Using Fields’ of the PARIS
Designer User’s Manual where examples are also given.
