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)

Date: kuupÀevamuutuja

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

Integer: tÀisarvmuutuja (-32768 - 32767)

Long: pikk tÀisarvmuutuja (-2.147.483.648 - 2.147.483.647)

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

Single: ĂŒksiktĂ€psusega ujukomamuutuja (3,402823 x 10E38 - 1,401298 x 10E-45).

String: maksimaalselt 64 000 ASCII-st koosnev stringmuutuja

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.

LibreOffice BASICus pole muutujaid vaja selgesĂ”naliselt deklareerida, kĂŒll aga tuleb enne kasutamist deklareerida massiivid. Muutuja deklareerimiseks saab kasutada lauset Dim. Deklaratsioonide eraldamiseks kasuta koma. MuutujatĂŒĂŒbi deklareerimiseks sisesta nime jĂ€rele tĂŒĂŒbideklaratsiooni mĂ€rk vĂ”i kasuta vastavat vĂ”tmesĂ”na.

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 toetab ĂŒhe- ja mitmemÔÔtmelisi massiive, mis on mÀÀratletud mÀÀratud muutujatĂŒĂŒbiga. Massiivid on sobivad siis, kui programm sisaldab loendeid vĂ”i tabeleid, mida soovid redigeerida. Massiivide eelis on see, et nende abil saab indeksite abil pöörduda ĂŒksikute elementide poole. Indeksid saab formuleerida arvavaldiste vĂ”i muutujatena.

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
  ' KahemÔÔtmeline andmevÀli
    Dim stext(20,2) As String
  Const sDim as String = " Dimensioon:"
  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
