This volume contains the proceedings of the 13th Colloquium on Trees in Algebra and Programming (CAAP '88), held in Nancy, March 21-24, 1988. The preceding 12 colloquia were held in France, Italy and Germany. CAAP '85 and CAAP '87 were integrated into the International Joint Conference on Theory and Practice of Software Development, TAPSOFT (see Lecture Notes in Computer Science volumes 185 and 249). As another effort to link theory and practice in computer science, CAAP '88 was held in conjunction with the European Symposium on Programming, ESOP '88 (see volume 300 of this Lecture Notes...

This book constitutes the refereed proceedings of the 7th International Joint Conference CAAP/FASE on Theory and Practice of Software Development (TAPSOFT'97), held in Lille, France, in April 1997.
The volume is organized in three parts: The first presents invited contributions, the second is devoted to trees in algebra in programming (CAAP) and the third to formal approaches in software engineering (FASE). The 30 revised full papers presented in the CAAP section were selected from 77 submissions; the 23 revised full papers presented in the FASE section were selected from 79 submissions.
