Can you pass an array through a function? And how do array pointer work?

If I recall correctly, a function can't return an array, it can only return a variable. However, one workaround is to set your dim your array as a global array which can then be updated by a function.

Every variable & array has a pointer, which means that with some commands you can call the pointer to that variable/array to change their content. I think you'll need Matrix Utilities for a lot of the pointer commands.

arrays are always global in dbpro, you don't need to pass them to a function, unless you are using abstraction where the function doesn't know or care what array it is working with, then you can pass an array pointer, which you will need to use matrix1. the matrix1 help files are good and should show everything you need to get and call the pointer
