Firstly, hello. This is my first post here. My name is Stan. I've been a 3D hobbyist for several years. I first found DB about a year ago, and have dabbled with it, but not really tried to do much with it...yet. When DBPro was announced I purchase the upgrade. Now, I have some time and am trying my first code experiments.

I'm new to DBPro and trying to figure out queues, lists and stacks. I'm not sure I understand their implementation in DBPro.

If I understand, a list or a queue is nothing more than a standard array initialized to a null, no elements, state. Then, the various queue, list, and stack commands are used to create, insert, and remove new blank elements into the array. This is were I get lost. It looks as though the current element of a queue, list, or stack is read/retrieve from array index '0' [ as in ArrayName(0) ]. The code below shows a test for creating and reading a simple queue. When run, it looks as though the queue is being created, but I cannot later read from the queue.

Any help would be appreciated.
TIA, Stan

I agree. Can someone explain how to use as help on these functions are complete bo***cks!

I can just about use stacks, just don't specify the '0'

i.e.

dim x()

add to stack x()
x()=1
add to stack x()
x()=2
remove from stack x()
print x()
queues are the same I think.

Yes, except that queues obviously remove from the front, and add to the back.

As long as you avoid inserting/delete at the top/middle of an array, all of the array handling routines work too.

Thanks for the reply. I had to read your post twice before I understood. Reading the documentation or help files I concluded that one must reference array index '0' explicitly in Queue, List, or Stack operations.

Oh well, minor annoyance as long as things work. Removing the index seems to solve the problem for queues, at least.

Learning the particulars of a new language is a double-edged sword constructed of fascination and frustration. (Zaara)
