Error Handling
Summary
The Formula language is a powerful, vital , and useful part of Domino application development. You cannot program in Domino without a solid understanding of this language. This chapter provided you with a foundation in the Formula language and discussed @Commands, @Functions, keywords, syntax, and more.
This chapter also introduced you to some of the methods that you can use to write formulas in Domino applications. You have covered a lot of ground, from types of formulas and statements to the different groups of @Functions, how to work with lists, methods of trapping errors, and debugging formulas. The Formula language is a very rich and mature language, and although this chapter has covered a lot of @Functions, many more are available. The help available in Domino Designer Help is generally excellent and quite thorough. Better yet, it is available when you are writing formulas. Writing formulas in forms, actions, views, hotspots, and more is discussed in the next chapter.
