Determines the value of the lower bound for the dimension of the array specified in the arguments.

Lbound expects the required argument ArrayName to be a valid variable array name. The optional argument ArrayDimension must be a whole long number indicating which dimension's lower bound is to be returned. Use 1 for the first dimension, 2 for the second, and so on.


Lbound(ArrayName, ArrayDimension)


The name of the array.


The dimension of the array for which you want to the lower bound. If ArrayDimension is omitted, 1 is assumed.

Return Value

Returns a number of Long data type.
