Abstract

This disclosure deals with improvements to the DIA MODIFY-DATA operand. This operand is used to make any changes to parameters within DIA objects. These parameters conform to the Document Interchange Architecture and must be changed according to the rules of the architecture. The MODIFY-DATA operand should be as flexible as possible to make modification of DIA Objects and parameters as easy as possible.

Modify-data Operand - Reset Operation

      This disclosure deals with improvements to the DIA MODIFY-DATA
operand. This operand is used to make any changes to parameters
within DIA objects. These parameters conform to the Document
Interchange Architecture and must be changed according to the rules
of the architecture. The MODIFY-DATA operand should be as flexible as
possible to make modification of DIA Objects and parameters as easy
as possible.

      The MODIFY-DATA operand was very limited in scope and function.
It only allowed the identification of a parameter by a set of three
fixed fields. It only allowed a value to be added to or deleted from
a parameter. It limited the length of a value to a maximum of 243
bytes. There was introduced to the architecture new parameters which
exceeded these boundaries and therefore could not be modified by the
existing MODIFY-DATA operand.

      The DIA MODIFY-DATA operand now supports Reset as an operation
code. The Reset operation specifies one or more MODIFY-ADD- VALUE(s).
The parameter specified in the OBJECT-IDENTIFIER is located. The
current value or values of the parameter are deleted. The parameter
is set to the new value or values specified by the
MODIFY-ADD-VALUE(s). The prior method to change a DIA parameter value
was to specify all current values for delete, before new values could
be added. The user was required to exactly specify each current
value, which implied the parameter must be retrieved before it co...
