No Sergey.
file name is ffiacc.prg
BTW we've been using it for many years.

I even tried new prg(with different name)and copied whole code there but to no avail :-(

There is only one prg class that calls abv prg and the calling code is ..

SET PROC TO FFIACC ADDITIVE
THIS.oFFI = FFIACC( THIS )
Release Proc FFIACC
