UBOUND - mkilgore/QB64pe GitHub Wiki

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

Syntax

result% = UBOUND(arrayName[,])

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
