The LBOUND function returns the smallest valid index (lower bound) of an array dimension.


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


Code Examples:

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

0 3
