This volume contains the background texts for an IFIP
State-of-the-Art Seminar on Formal Program Development, held
in early 1992 near Rio de Janeiro, Brazil.
The book stems from work done by IFIP Working Group 2.1 on
Algorithmic Languages and Calculi. Since 1975, the Working
Group has increasingly focused on systematic approaches to
programming and on appropriate concepts and notations to
support such approaches. Today, the calculation of programs
from specifications constitutes the central theme ofthe
group's work. Thus the core interests of the group are:
- formal specification of solutions to problems, and
- formal development/calculationof programs from such
specifications.
