Continuum radio emission and fine structure (in particular millisecond spikes) have recently raised interest as diagnostic tools for the interpretation of energy release and particle acceleration in flares. In the circles of the European solar radio astronomers, loosely organized in CESRA, the idea of a workshop came up intended for active observers of the impulsive phase of flares in radio and associated emissions. The scientific organizing committee included A.D. Benz (chairman), A. Magun, M. Pick, G. Trottet, and P. Zlobec. The workshop was held on May 27-31, 1985 in the castle of Duino near Trieste, Italy. The meeting intended to find a common terminology, to compare radio observations with measurements in other emissions and to confront observations with theoretical concepts. We have achieved a representative summary on the current status of the field and a clear perspective for the next cycle. This volume contains the reviews and a selection of contributions and extended abstracts of papers presented at the workshop. I wish to thank the local organizers, in particular A. Abrami, M. Comari, F. Depolli, L. Fornasari, M. Messerotti (chairman), M. Nonino, and P. Zlobec. Financial support was graciously provided by the Italian Research Council (CNR). Most of all, however, I would like to express my thankfulness to our host, His Highness Prince Raimondo della Torre e Tasso, for his invaluable hospitality. We are deeply sorry to hear of his passing in the meantime. To his memory these proceedings are dedicated.

`... the book ought to become the basis for a common terminology in the field of fine structure or radio continua. Therefore, the book is strongly recommended to specialists in solar physics.'
