This article was previously published under Q103595 SUMMARY
The l_subs member of the Locator structure for arrays passed by reference
is not set appropriately when the function is invoked. To obtain subscript
information for an array, call the _ALEN() function using the l_NTI member
of the Locator structure.
MORE INFORMATION
When using ALEN() with the mode AL_SUBSCRIPT2, a return of 0 means that the
array is one dimensional. Otherwise, you receive the second dimension of
the array.
AL_SUBSCRIPT1 returns the first dimension of the array.
AL_ELEMENTS returns the total number of elements in the array.
