UBOUND

Syntax

UBound(<array variable>)
UBound(<array variable>, <dimension>)

Description

Returns the array upper bound of the given . If the is not specified, it defaults to 1. If the specified is 0, then total number of dimensions is returned.

Examples

DIM a(3 TO 5, 2 TO 8)
PRINT UBound(a, 2) : REM Prints 8
PRINT Ubound(a) : REM Prints 5, because dimension defaults to 1

The result is always a 16bit integer value.

If the is 0, then the number of dimension in the array is returned (useful to guess the number of dimensions of an array):

DIM a(3 TO 5, 2 TO 8)
PRINT UBound(a, 0): REM Prints 2, since 'a' has 2 dimensions

Remarks

  • This function does not exists in Sinclair BASIC.
