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.
