LBOUND

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

Example(s)

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

PRINT LBOUND(myArray)
PRINT LBOUND(myOtherArray, 2)
