Name Value Behavior
DefineOverwrite 0
The content of the value parameter overwrites the current value of the field if it exists, or creates it if
it does not.
DefineAppend 1 The content of the value parameter is appended to the existing field.
DefineDuplicate 2 A new field with the same name is created, appending an index at the end of its name.
DefineError 3 The command fails and the job crashes, yielding an error dialog.
path
Optional string value to specify the level where to create the metadata field. Path components cannot be indexed, and if no
path is provided, the field is created at the current page level.
The node names of the path argument can have an optional zero-based index, indicated between square brackets ('[
]'), to access a specific node. If no index is provided, the first node is used.
Code Sample Example
This example illustrates how to assign data from the current line printer data file to a document-based metadata field, spec-
ifying the level where the field will be created.
% Create simple 'InvoiceNumber' holding the value found on line 10,
% between columns 35 and 42 of a line printer emulation data file.
definemeta('InvoiceNumber', @(10,35,42))
% Create the same 'InvoiceNumber' field but duplicating it if it already exists.
definemeta('InvoiceNumber', @(10,35,42), 2)
% Create the same 'InvoiceNumber' field but at the Document level this time,
% and raising an error if it already exists.
definemeta('InvoiceNumber', @(10,35,42), 3, 'Job.Group.Document')
