Declaration: Boolean did_map_aggregate_arg
(void (* proc ) (EStackIndex, EStackIndex), EStackIndex i , EStackIndex j )
Category(ies): Lists and Matrices
Description: Determines if i and/or j index aggregates.
A NON_CONFORMING_LISTS_ERROR is thrown if i and j index
nonconforming aggregates.
Inputs: proc — Address of a procedure that takes two EStackIndex arguments.
i , j
Outputs: If i and/or j index aggregates, maps proc over their elements then returns
TRUE. Otherwise returns FALSE.
Assumptions: None
Side Effects: None
Availability: On AMS 2.04 and higher.

/* Title: push_dot_mult
** Description: push element by element product of two arguments
** onto the estack
** Input: estack index i of the first simplified argument
** estack index j of the second simplified argument
** Output: pushes the element by element product onto the estack
