{{PageDescription}}
|
|
* {{Parameter|arrayName}} specifies the name of the array.
|
|
* {{Parameter|dimension%}} specifies the dimension number, starting with <code>1</code> for the first dimension.
|
|
** If omitted, {{Parameter|dimension%}} is assumed to be <code>1</code>.
|
|
** If {{Parameter|dimension%}} is less than <code>1</code> or is greater than the number of dimensions, a [[ERROR Codes|subscript out of range]] error occurs.
|
|
* [[LBOUND]] and [[UBOUND]] are used to determine the range of valid indexes of an array.
