Re: Using pointers to manage like arrays?

For a report I'm developing, I need to track the top ten quantity and cost
for a department, as well as for the entire report. I have two
identical-in-kind arrays, but I have to process each of them twice (once for
cost, again for quantity). Since the arrays are defined identically, I want
to halve the code: process cost or process quantity, regardless of which
array it is. I feel like there is a solution involving basing the arrays on
a pointer but haven't wrapped my head around it.

For your immediate question you'll need a third array. This will have an identical layout to the existing arrays but be BASED on a pointer. Load the data arrays as normal (you still need somewhere to hold the data) and then set the basing pointer to the %ADDR of the array you actually intend to process. Your code only refers to the based array.
