Commercial Microfinance and Povertyerrors were found and corrected. The output of the literal algebra program (SPASM) was Fortran arithmetic statements, which were compiled to produce a program that would evaluate the perturbations. SPASM operates directly on symbolic expressions. Some advantages of this approach over table-driven algebraic processors are observed.

https://doi.org/10.1007/3-540-30724-9ystem are combined in a global solution for gravity-field parameters and station coordinates. The data base represents a significant improvement on previous work, with increased accuracy and better distribution. The gravity field is given complete to 14th degree and order, and more than 29 station nets are determined.
