**v1.01.103** ZZZZ103 — Unit tests of basic functions of the Jeveux memory manager
==============================================================================================

**Summary:**

This test makes it possible to verify the operation of basic utilities of the memory manager JEVEUX.

Modeling A prints values associated with platform-dependent numerical constants. In particular the lengths and extreme values of integers and floating numbers, some particular mathematical constants, and some parameters related to the use of memory and files. The values can be accessed using the ENVIMA functions described in document [:ref:`D6.01.01 <D6.01.01>`].

Modeling B verifies that the database extension functionality is triggered (on the volatile base) in case of lack of RAM and space in the previous database.

The C modeling verifies the functionality of extending the databases on a global basis, as well as the resetting.

This documentation is deliberately brief.
