The translation approaches

From top level, a FORTRAN library is converted into a Java package, a FORTRAN file, filename.f, is converted into a Java file, filename.java, and each FORTRAN program unit is turned to a Java class.

Besides, the following issues are addressed in the converter.

• Naming conventions
• How to produce a class
• Subprogram invocation mechanism
• About data types
• FORTRAN specific statements
  • COMMON statement
  • EQUIVALENCE statement
  • Labeled DO statement
• I/O and FORMAT statement
