(Abstract)

This paper described the features of some programmes which enhance the existent software of the TIOPS-computer.
The approached problems are:
– velocity estimation in seismic prospecting:
– frequency domain filtering, by time-windows;
– terrain corrections in gravitational interpretation.
The programmes are written in assembly language of the TIOPS-computer.
