Hi Denis,

>In parm->p[0].val i see ev_real part... but it is real value... How can I get a day,year and months from this value ?

From the VFP help file:

1. The date is represented as a double-precision floating-point Julian day number calculated using Algorithm 199 from Collected Algorithms of the ACM.

You don't have to know the algorithm, just pass a known date and use the date and corresponding number to determine the actual date. I haven't checked it, but SYS(11) and SYS(11) might use the same algorithm.
