The {{KW|UBOUND}} function returns the largest valid index (upper bound) of an array dimension.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:''result%'' = {{KW|UBOUND}}(arrayName[, dimension%])
|
|
|
|
|
|
{{PageDescription}}
|
|
* {{Parameter|arrayName}} specifies the name of the array.
|
|
|
|
* {{Parameter|dimension%}} specifies the dimension number, starting with '''1''' for the first dimension.
|
|
** If omitted, {{Parameter|dimension%}} is assumed to be '''1'''.
|
|
** If {{Parameter|dimension%}} is less than '''1''' or is greater than the number of dimensions, a [[ERROR Codes|subscript out of range]] error occurs.
|
|
|
|
* {{KW|UBOUND}}, along with {{KW|LBOUND}}, is used to determine the range of valid indexes of an array.
