Turbo Pascal, a compiler for the personal computer, was investigated to determine if it is compatible with the calculations required by Structural engineers. The compiler was evaluated for calculation intensive programming as well as programming for data manipulation. A processor and a preprocessor for a plane frame program were used because they test the power of the language for calculations and they require the software to be user friendly and highly flexible with regard to manipulation of data. A description of the development and a user's guide to the programs are included. / M.S.
