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.
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 |
