Syntax

result% = LBOUND(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 ERROR Codes error occurs.
  • LBOUND and UBOUND are used to determine the range of valid indexes of an array.
