    • 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.

      • Script and Statement Construction Rules

        This chapter describes the rules for writing the basic elements of a script in the LotusScript® language.

      • Data Types, Constants, and Variables

        This chapter provides information about LotusScript® constants and variables and the data types of the values that they can represent.

      • 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.

        • Overview of expressions and operators

          An operand is a language element that represents a value, and an operator is a language element that determines how the value of an expression is to be computed from its operand or operands. A unary operator performs an operation on a single operand, and a binary operator performs an operation on two operands. An expressionis a sequence of operators and operands that evaluates to a single value at run time.

        • Operator order of precedence

          You determine the value of an expression by the order in which the parts are evaluated. Operators with greater precedence are evaluated before operators with less precedence. Operators with the same precedence are evaluated from left to right.

        • Arithmetic operators in LotusScript®

          When an arithmetic expression contains a NULL operand, the expression as a whole evaluates to NULL.

        • Relational (comparison) operators

          Relational operators (also called comparison operators) compare two expressions.

        • Logical Operators

          You use the logical operators And, Or, Xor, Eqv, and Imp to perform two kinds of operations:

        • Table of string operators

          You can use these operators in expressions whose operands represent string values:

        • Is operator (LotusScript® Language)

          Compares two object reference variables.

        • IsA operator (LotusScript® Language)

          Determines if an object reference variable is of a specified class or a class derived from the specified class.

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

        This chapter describes file handling in the LotusScript® language.

        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.
