This project involved substantial modifications to an existing Fortran compiler, bringing it up from F77 standards to F90 standards. Since the ANSI Standards parsing requirements were so radically different, the entire parsing mechanism was rebuilt.
The core of this system relied on an intermediate language (IL) designed specifically for writing compilers. The IL was written in Assembly Language as were many of the Runtime Library routines
Since the client was located on the east coast, most of the works was dome remotely using TCP/IP file transfer tools as well as diff and merge tools.
This project also involved creating and maintaining a set of version control project files.
Languages: Fortran, Assembly Language, Intermediate Language
