The release of Domino 6 brings several new rich features and enhancements to the script functions and @Functions that are long overdue. LotusScript is not always the best use of a developer's time: It can appear to be intimidating and a lot of extra work. Nevertheless, @Functions' capabilities pale in comparison to those of LotusScript, which touts heavy-duty processing power versus the simple functions of @Functions. Domino 6 does bring new @For , @While , and @DoWhile macro language functions, which were not included in previous versions and forced developers into using LotusScript for automated routines. Generally, however, LotusScript should be used when simple functions cannot. Use LotusScript when automating complex routines, performing iterative operations, or handling transactions.
This chapter provides you with several real-world LotusScript routines that will help you dive right in if you're not familiar with the language. At the very least, it will provide you with some good working solutions that you might or might not already have in your own code repertoire .
Just remember that there are many ways in which to approach scripting with LotusScript, just as many as there are ways to develop a solution to a problem in Domino. You might have a different style or set of rules that you approach and apply to scripting with LotusScript. Don't think that one way is the only way. The best advice anyone can give you is to keep your script simple: Someone might have to come after you and support it. Provide comments in your code: Someone might have to come after you and rewrite it. And keep it organized: Someone might have to come after you and add functionality to the routines. There is no worse headache than having to re-engineer someone else's mess!
Each of the scripts used throughout this chapter will be separated into code blocks, and each block's description and purpose will be discussed in turn . At the end of each script discussion, the script is shown in its entirety. These examples also assume that you have some basic knowledge of LotusScript, know how to program it in the IDE, and are familiar with its back-end and front-end classes.
Overall, each of these scripts shows you how to perform real-world tasks using LotusScript and proven methods . Each contains useful routines and subroutines that can be used repeatedly and make your applications even more powerful at the same time.
