Function Data File
==================

Function data files are tab-delimited text files for storing :doc:`utility
functions <DEXiGlosFunct>`, which are exported and imported
through 'Export function' and 'Import function' :doc:`File
Menu <DEXiIntMenuFile>` commands, respectively. One file contains
one utility function, whose format can be specified with
:ref:`Settings/Import-Export <DEXiIntSett_iex>`.

Examples
--------

1. TECH.CHAR. function from the :doc:`Car Evaluation <DEXiCar>` model,
exported in tab-delimited format, using 'base 1' values and exporting
all rules. The character '+' represents an entered rule. The TAB
character is denoted '¬'.

| ``¬COMFORT¬SAFETY¬TECH.CHAR.``
| ``1¬1¬1¬1¬+``
| ``2¬2¬1¬1¬+``
| ``3¬3¬1¬1¬+``
| ``4¬1¬1¬1¬+``
| ``5¬2¬2¬2¬+``
| ``6¬3¬3¬3¬+``
| ``7¬1¬1¬1¬+``
| ``8¬2¬3¬3¬+``
| ``9¬3¬4¬4¬+``

2. The same function exported using text values and exporting only
entered rules (in this case there is no need to display the '+' or '-'
entered status).

| ``¬COMFORT¬SAFETY¬TECH.CHAR.``
| ``1¬bad¬bad¬bad``
| ``2¬acc¬bad¬bad``
| ``3¬good¬bad¬bad``
| ``4¬bad¬bad¬bad``
| ``5¬acc¬acc¬acc``
| ``6¬good¬good¬good``
| ``7¬bad¬bad¬bad``
| ``8¬acc¬good¬good``
| ``9¬good¬exc¬exc``
