Yes, I found both files in the library. Thank you (and Fernando Pereira who
answered by mail)!
The random number generator works fine but the consulting of 'date.pl'
wasn't successful:

yes

Then I tried to compile 'date.c' directly:

----------------------------------------------------------------------
gandalf:~/prolog/dp/date 111> gcc date.c
date.c: In function `QD4mat':
date.c:358: warning: suggest parentheses around && within ||
ld:

QP_atom_from_string
collect: /usr/bin/ld returned 1 exit status
----------------------------------------------------------------------

It seems that 'QP_atom_from_string' is not defined.

What might help???

Thanx in advance and have a nice weekend,
