UBound() function - MapBasic - 2023

Purpose

Returns the current size of an array. You can call this function from the MapBasic window in MapInfo Pro.

Syntax

UBound( array )

array is the name of an array variable.

Return Value

Integer

Description

The UBound() function returns an integer value indicating the current size (or "upper bound") of an array variable.

Every array variable has an initial size, which can be zero or larger. This initial size is specified in the variable's Dim statement or Global statement. However, an array's size can be reset through the ReDim statement. The UBound() function returns an array's current size, as an integer value indicating how many elements can currently be stored in the array. A MapBasic array can have up to 32,767 items.

Example

Dim matrix(10) As Float
Dim depth As Integer

depth = UBound(matrix) 
' depth now has a value of 10

ReDim matrix(20) 
depth = UBound(matrix) 
' depth now has a value of 20
