Operands
=========


Operand UNITE
--------------


.. code-block:: text

    ♦ UNITE = u

Logical unit number of the external file on which the reading is done.


Operand FORMAT
---------------

Define the reading format:


* 'ASTER' by default,


* 'IDEAS' if you read results obtained with IDEAS


Operand FORMAT_C
-----------------

Define the reading format for complex functions:


* 'MODULE_PHASE' by default,


* 'REEL_IMAG' real part and imaginary part.


Operand NOM_PARA
-----------------

Defines the name of the function parameter (x-axis). By default we take 'FREQ'.


Operand NOM_RESU
-----------------

Define the name of the result of the function (ordinate)


Operands PROL_DROITE/PROL_GAUCHE
-----------------------------------


.. code-block:: text

    ◊ PROL_DROITE =

Defines the extension of the function to the right of the variable's domain of definition.


.. code-block:: text

    ◊ PROL_GAUCHE =

Define the extension of the function to the left of the variable's domain of definition:


.. csv-table::

    "* 'CONSTANT'", ""
    "* 'LINEAIRE'", "for an extension along the first defined segment (PROL_GAUCHE) or the last defined segment (PROL_DROITE)."
    "* 'EXCLU'", "if extrapolation of values outside of the parameter definition domain is prohibited."



Operand INTERPOL
-----------------


.. code-block:: text

    ◊ INTERPOL =


* 'LOG' logarithmic interpolation between two values in the domain of definition.


* 'LIN' linear interpolation between two values in the domain of definition.


Operand INFO
-------------


.. code-block:: text

    ◊ INFO =

Specify the options for printing on the message file.


.. csv-table::

    "1", "printing function attributes: number of definition points, parameter and result names, as well as extension and verification options"
    "2", "like 1plus the list of the first 10 values of each function in ascending order of the parameter"


For example:


* PROL_DROITE = 'CONSTANT', PROL_GAUCHE = 'CONSTANT'
