hi Paul,

thanks for your answer.

I didn't know what 'reentrant' means. I went on wikipedia :

`` A computer program or routine is described as reentrant if it is
designed such that a single copy of the program's instructions in memory
can be shared by multiple users or separate processes. The key to the
design of a reentrant program is to ensure that no portion of the program
code is modified by the different users/processes, and that process-unique
information (such as local variables) is kept in a separate area of memory
that is distinct for each user or process.''
