A Fortran compiler for the PDP-11/34 minicomputer

The subject of this thesis is the design of a FORTRAN compiler for the PDP-11/34 minicomputer owned by the Dept. of Mathematical Sciences of Ball State University, Muncie, Indiana. At the time that this project was undertaken, only the BASIC and ASSEMBLY languages were available on this machine.The problem consisted of writing a two-pass processer. The function of the first pass was to recognize FORTRAN statements, analyze them syntactically and semantically, build symbol tables, and construct an output file containing pointers to the symbol table, flags, and operators. The second pass used the output file of the first part and the symbol tables to build ASSEMBLY language instructions equivalent to the FORTRAN instructions in function.Ball State UniversityMuncie, IN 47306
