Dim Statement

Declares variables or arrays.

If the variables are separated by commas - for example Dim v1, v2, v3 As String - first ones get defined as Variant variables. A new line, or colon sign (:), help separate variable definitions.

  Dim text As String
  Dim pv As com.sun.star.beans.PropertyValue, d As Date
  Dim Units as Integer : Dim EULER As Double

Dim declares local variables within subroutines. Global variables are declared with the Global, Public or the Private statement.

Dim variable [(start To end)] [As typename][, variable2[char] [(start To end)] [,...]]

New operator is optional when setting Option Compatible option.

variable: Any variable or array name.

typename: Keyword that declares the data type of a variable.

Byte: Byte variable (0-255)

Boolean: Boolean variable (True, False)

Currency: Currency variable (Currency with 4 Decimal places)

मिति: चल मिति

Double: Double-precision floating-point variable (1,79769313486232 x 10E308 - 4,94065645841247 x 10E-324)

इन्टिजर: चल इन्टिजर (-३२७६८ - ३२७६७)

लामो: लामो इन्टिजर (-२.१४७.४८३.६४८ - २.१४७.४८३.६४७)

Object: Object variable (Note: this variable can only subsequently be defined with Set!)

एकल: एकल-शुद्धिकरण उत्प्लावन-बिन्दु चल (३,४०२८२३ x १०E३८ - १,४०१२९८ x १०E-४५)

String: String variable consisting of a maximum of 2,147,483,647 characters.

Variant: Variant variable type (contains all types, specified by definition). If a type name is not specified, variables are automatically defined as Variant Type, unless a statement from DefBool to DefVar is used.

object: Universal Network object (UNO) object or ClassModule object instance.

char: Special character that declares the data type of a variable.

In LibreOffice Basic, you do not need to declare variables explicitly. However, you need to declare arrays before you can use them. You can declare a variable with the Dim statement, using commas (,) to separate multiple declarations. To declare a variable type, enter a type-declaration character following the name or use a corresponding type keyword name.

array: Array declaration.

start, end: Numerical values or constants that define the number of elements (NumberElements=(end-start)+1) and the index range.

start and end can be numerical expressions if ReDim is applied at the procedure level.

LibreOffice आधारभूत समर्थन निर्दिष्ट गरिएका चल प्रकारद्वारा परिभाषित गरिएका एकल वा बहु -आयामित एरेहरू । तपाईँले सम्पादन गर्न चाहनुभएको कार्यक्रम सामाग्रीहरूमा सूचीहरू वा तालिकाहरू भएमा एरेहरू अनुकूल हुन्छन् । एरेहरूको फाइदा त्यो हुन्छ कि अनुक्रमणिका अनुसार हरेक तत्वहरूको सम्वोधन गर्न सम्भव हुन्छ, जसलाई सङ्ख्यात्मक अभिव्यक्ति वा चलहरूको रूपमा सूत्रबद्ध गर्न सकिन्छ ।

Arrays are declared with the Dim statement. There are multiple ways to define the index range:

  Dim text(20) As String ' 21 elements numbered from 0 to 20
  Dim value(5 to 25) As Integer ' 21 values numbered from 5 to 25
  Dim amount(-15 to 5) As Currency ' 21 amounts (including 0), numbered from -15 to 5
  REM Two-dimensional data field
  Dim table$(20,2) ' 63 items; from 0 to 20 level 1, from 0 to 20 level 2 and from 0 to 20 level 3.

You can declare an array types as dynamic if a ReDim statement defines the number of dimensions in the subroutine or the function that contains the array. Generally, you can only define an array dimension once, and you cannot modify it. Within a subroutine, you can declare an array with ReDim. You can only define dimensions with numeric expressions. This ensures that the fields are only as large as necessary.

Sub ExampleDim1
Dim sVar As String
Dim iVar As Integer
    sVar = "Office"
End Sub
 
Sub ExampleDim2
  ' द्वि-आयामिक डेटा फाँट
    Dim stext(20,2) As String
  स्ट्रिङको रूपमा Const sDim = " आयामिक:"
  For i = 0 To 20
    For ii = 0 To 2
        stext(i,ii) = str(i) & sDim & str(ii)
    Next ii
  Next i
  For i = 0 To 20
    For ii = 0 To 2
        MsgBox stext(i,ii)
    Next ii
  Next i
End Sub
