UBOUND

The UBOUND function returns the largest valid index (upper bound) of an array dimension.

Syntax

result% = UBOUND(arrayName[, dimension%])

Description

• arrayName specifies the name of the array.

• dimension% specifies the dimension number, starting with 1 for the first dimension.
  • If omitted, dimension% is assumed to be 1.
  • If dimension% is less than 1 or is greater than the number of dimensions, a subscript out of range error occurs.

• UBOUND, along with LBOUND, is used to determine the range of valid indexes of an array.

Examples

DIM myArray(5) AS INTEGER DIM myOtherArray(1 to 2, 3 to 4) AS INTEGER PRINT UBOUND(myArray) PRINT UBOUND(myOtherArray, 2)

5 4
