LBound function
Returns the minimum available subscript for the specified array dimension.
LBound(arrayname[, dimension])
parameter
arrayname
Array variable names follow the standard variable naming convention.
Dimension
Indicates which dimension of the lower bound to return. Use 1 for the first dimension, 2 for the second dimension, and so on. If omitteddimensionParameter, default value is 1.
illustrate
LBoundFunctions andUBoundFunctions are used together to determine the size of an array. useUBoundFunctions can find the upper bound of a certain dimension of an array.
The lower bound of any dimension is 0.
