Exception Handling in FORTRAN 2000
FORTRAN 2000异常处理机制的研究

Exception handling.an important feature of modern programming languages,provides a strong support for detecting and recovering runtime errors,and structuring fault-tolerant activities in a system. This paper analyzes the exception handling mechanism of FORTRAN 2000, and proposes a extension through introducing user defined exceptions, exception handler and improving propagation mechanisms, thus make normal code and exception handle code separate better,and increase the readability and maintainability of programs.
