HCL Domino Designer Basic User Guide and Reference
This guide provides information on using HCL Domino Designer and programming language reference information.
Connectors
Connectors provide native access to a wide variety of DBMS products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems.
LSX for Connectors
LotusScript® Extensions for Connectors (LC LSX) enhances the power of Notes® by extending its scripting to data outside of Notes through the use of Connectors. The programming model is independent of the individual connector. This eliminates the need to learn each individual system, while at the same time allowing experienced users to access the individual features of a specific system.

- 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.
- DB2® Access views
  Domino® Designer includes two types of design elements to assist you in managing data contained in DB2® enabled Notes® databases:
- Programming Overview and User Interface
  This section contains general guidelines and examples that show where to use Java, LotusScript, and the formula language.

  - LSX for Connectors
    LotusScript® Extensions for Connectors (LC LSX) enhances the power of Notes® by extending its scripting to data outside of Notes through the use of Connectors. The programming model is independent of the individual connector. This eliminates the need to learn each individual system, while at the same time allowing experienced users to access the individual features of a specific system.
    - Chapter 1 Introduction
      This chapter provides an introduction to the LotusScript® Extension for Connectors (LC LSX) and explains the organization of this manual.
    - Chapter 2 LCConnection Class
      This chapter provides information about the LCConnection class methods and properties.
    - Chapter 3 LCCurrency Class
      This chapter provides information about the LCCurrency class methods and properties.
      - LCCurrency class overview
        The LCCurrency class represents a currency value and has the same format and restrictions as the LotusScript® currency data type. The value is an 8-byte integer with a fixed scale of 4 decimal places, providing 19 digits of precision. Currency is commonly used when higher precision is required, such as for monetary amounts. A currency is much more precise than an integer, more precise than a float, and more efficient (but less precise) than a numeric. Note that during any currency overflow, the maximum or minimum valid currency value is assigned in addition to the error generated.
      - Syntax for HEI Scripted Activities - 6
        When writing LotusScript® Extensions (LC LSX) scripts for HEI Scripted Activities, you must specify Dim LCSession as a named session (this becomes the default log document name). LCConnections must also be dimensioned as existing, named HCL Enterprise Integrator (HEI) connection documents.
      - Type CURRENCY Format and Values
        The following table shows CURRENCY format and values.
      - LCCurrency Class Methods Summary
        The following are the LCCurrency class methods:
      - LCCurrency Properties
        LCCurrency has two properties: Text and Value.
      - New Method for LCCurrency
        This is the constructor for LCCurrency. It initializes a currency object.
      - Add Method for LCCurrency
        This method adds two LCCurrency values, producing the sum. The sum is returned to the object that is making the call.
      - Compare Method for LCCurrency
        This method compares two currency values and returns the relationship.
      - Copy Method for LCCurrency
        This method makes a copy of an LCCurrency object.
      - Subtract Method for LCCurrency
        This method subtracts one LCCurrency value from another, producing the result. The result is stored in the object that is making the call.
      - Example: LCCurrency with LCFieldlist and LCField
        This example illustrates the use of LCCurrency in conjunction with the LCFieldlist and LCField options.

Subtract Method for LCCurrency

This method subtracts one LCCurrency value from another, producing the result. The result is stored in the object that is making the call.

Defined In

LCCurrency

Syntax

Call currencyResult.Subtract (currency1, currency2)

Parameters


Parameter	Description
currency1	LCCurrency. This is the initial LCCurrency from which you want to subtract the second currency.
currency2	LCCurrency. The amount to be subtracted from currency1.

Usage Notes®

The currencyResult may be the same object as one of the arguments, for example:

Call remainingAmt.Subtract(remainingAmt, deduction)

CurrencyResult must have been initialized prior to the call, that is, it cannot be Nothing.

Example

Option Public
Uselsx "*lsxlc"  
Sub Initialize
  Dim num1 As New LCCurrency //For HEI
  Dim num2 As New LCCurrency
  Dim diff As New LCCurrency
  num1.Value = 98765.4321
  num2.Value = 12345.6789
  Call diff.Subtract (Num1, Num2)
  Print "The difference of the two currencies is " & diff.Text
End Sub

Example Output

The difference of the two currencies is 86419.7532.
