Instrucción ReDim

Sintaxis:

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)

Date: Variable de fecha

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

Integer: Variable entera (-32768 - 32767)

Long: Variable larga (-2.147.483.648 -2.147.483.647)

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

Single: Variable de precisión simple y coma flotante (3,402823 x 10E308 -1,401298 x 10E-45).

String: variable de cadena que se compone de un máximo de 64 000 caracteres ASCII.

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 Collabora Office 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.

Collabora Office Basic admite matrices de una o varias dimensiones, definidas por un tipo de variable especificado, que resultan útiles si el programa contiene listas o tablas que se desea editar. La ventaja de las matrices es que es posible acceder a elementos individuales utilizando índices, los cuales pueden formularse como expresiones numéricas o variables.

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.
