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)] [,...]]


variable: Any variable or array name.

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

primitive data types fragment

Byte: Byte variable (0-255)

Boolean: Boolean variable (True, False)

Currency: Currency variable (Currency with 4 Decimal places)

Guyyaa: Jijjiirama guyyaa

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

Itergaa: Jijjiirama Itergaa (-32768 - 32767)

Dheeraa: Jijjiirama itergaa dheeraa (-2.147.483.648 - 2.147.483.647)

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

Baxxee: Jijjiiramaa sirrummaa-baxxee tuqaa bololi'aa variable (3,402823 x 10E38 - 1,401298 x 10E-45).

Diraa: Jijjiiramaa diraan arfoota ASCII alaantoo 64,000 of keessaa qaba.

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.

Type declaration characters fragment

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.

Variable type name













array: Array declaration.

array fragment

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 Basic waraantoo rog-baaqqee ykn danuu kan akaakuu jijjiiramaan ifteefame gargaara. Yoo sagantaan tarree ykn gabatee gulaaluu barbaaddu qabaate waraantoon mijaawadha. Bu'aan waraantoo miseensota tokkoo tokkoo akkaataa kasootatti furuu danda'uu, kan akka himannoo ykn jijjiiramaa lakkoofsaatti ashakame.

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
  Dirree deetaa rog-lamee
    Dim stext(20,2) As String
  Const sDim as String = " Dimension:"
  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
