Modern operating systems besides of their many advantages raise compatibility issues for programs compiled in former languages. It is one of the reasons why the new program for numerical analysis of positron annihilation lifetime spectra was built. As it is the continuation of well known LT series it inherits most of the features available and solutions used in LT (numerical routines and analysis logic). Like in previous versions, operating on series of spectra makes possible to correlate selected parameters belonging to different spectra of a series. Despite of features already implemented earlier, designing new version was perfect opportunity to include features yet unavailable in other versions of the program. Moreover, the completely new user interface was designed to make those features easy to use. New structure of the program supported with checked logic makes the computer analysis flexible and versatile.
