Variant::ArrayLowBound Method

Returns the low bound of the given dimension in the given variant array.

function ArrayLowBound(const dim: Integer = 1): Integer;
__fastcall int ArrayLowBound(const int dim = 1) const;

The dim parameter should be 1 for the leftmost dimension, 2 for the second leftmost dimension, and so on. An ESystem::Variant::VariantError exception is raised if the variant given by A is not an array, or if the dimension specified by dim does not exist.
