Returns information about the dimensions of the array whose name table index is nti.
Syntax
long _ALen(NTI nti, int mode)
NTI nti; /* Array name table index. */
int mode; /* Mode to determine return value. */
Remarks
If mode is AL_ELEMENTS, _ALen( ) returns the total number of elements in the array. If mode is AL_SUBSCRIPT1, _ALen( ) returns the value of the first subscript used to declare the array. If mode is AL_SUBSCRIPT2, _ALen( ) returns the value of the second subscript used to declare the array.
If nti doesn't represent the name of an existing array, _ALen( ) returns – 1 regardless of the value of mode.
