    • Domino® Query Language

      Domino® Query Language (DQL) is a facility running on a Domino server that provides a terse, shorthand syntax for finding documents. It supports a wide variety and complexity of search terms. It leverages existing design elements, avoiding the need to write detailed code to access them. DQL consolidates all methods in Domino for searching document contents.

    • Composite Applications - Design and Management

      Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.

    • LotusScript® Language

      Welcome to the LotusScript® Language section of Domino® Designer Help.

      • Introduction to LotusScript®

        This chapter introduces LotusScript® and describes, in general terms, how to use the script editor to write and modify scripts, how to compile scripts, and how to use the debugger to locate problems in the logic of your applications.

      • Expressions and Operators

        This chapter describes the set of LotusScript® operators, how they may be combined with operands to form expressions, and how those expressions are evaluated.

      • Procedures: Functions, Subs, and Properties
      • File Handling

        This chapter describes file handling in the LotusScript® language.

        • File operations

          The following table describes the three kinds of files in LotusScript®: sequential, random, and binary.

        • Sequential files

          A sequential file is an ordinary text file. Each character in the file is assumed to be either a text character or some other ASCII control character such as newline. The character is in the character set specified when the file is opened. By default this is the platform-native character set.

        • Random files

          A random file is made up of a series of records of identical length. A record can correspond to a scalar data type, such as Integer or String, or to a user-defined type, in which each record is broken down into fields corresponding to the members of the type.

        • Binary files

          Binary files are designed to provide the most control over the organization of your data for both reading and writing. However, you must know exactly how the file was written.

        • Reading, writing, and closing files

          You can use LotusScript® to read and write files. To create a file, you open and write to a file that does not yet exist; LotusScript creates it automatically.

      • Error Processing

        This chapter describes error processing in the LotusScript® language.

      • User-Defined Data Types and Classes

        This chapter describes two kinds of custom data structures that you can define in LotusScript®. Each can hold data of different types in a single data structure.

      • Managing Flow in Scripts

        The flow of execution of a script generally follows the sequence of statements in the script. This chapter describes the behavior of particular statements that alter the flow of execution.

      • Managing Asynchronous Web Agents in Domino®

        This chapter describes how to use multiple threads and synchronization to manage HTTP agents with Domino®.

      • Beyond Core LotusScript®

        This chapter discusses the role that LotusScript® plays with HCL products, your operating environment, other programs, and interactive user applications.

      • LotusScript® Language Reference

        This chapter describes the use of statements, built-in functions, subs, data types, and directives in the LotusScript® language.

      • Language and Script Limits

        This appendix describes LotusScript® language limits of several kinds: for example, the legal ranges in data representation, the limits on numerical specifications within statements, and the maximum number of different kinds of elements that can be defined in a script.

      • Platform Differences

        The LotusScript® language and functionality on the UNIX™ platform, the Macintosh platform, and the IBM i® platform differ in various ways from the language and functionality described in the rest of this language reference. This appendix describes the differences.
