Abstract

The author surveys some of the lessons learned in conversion projects for FORTRAN and BASIC into Ada, and in interfacing FORTRAN into Ada. He discusses design issues to be explored and resolved before coding begins. In general, problems will be found not in the control constructs of the languages (loops, IF-THEN statements, error exception handling) but in the representation of data types, and, to a lesser extent, the mathematical operations performed on various types. Examples show what to look for during design to prevent pitfalls encountered during coding and testing. Some solutions may require debugger analysis, while others may be implemented with specific coding practice (hence making the Ada host-specific).<>

痛苦与胜利:将其他语言转换或接口到Ada的经验教训

作者调查了从FORTRAN和BASIC到Ada的转换项目中获得的一些经验教训，以及将FORTRAN与Ada接口。他讨论了在编码开始之前需要探索和解决的设计问题。一般来说，问题不在于语言的控制结构(循环、IF-THEN语句、错误异常处理)，而在于数据类型的表示，以及在较小程度上对各种类型执行的数学运算。示例展示了在设计过程中应该寻找什么，以防止在编码和测试过程中遇到陷阱。一些解决方案可能需要调试器分析，而其他解决方案可能通过特定的编码实践来实现(因此使Ada特定于主机)。
