Just a Few Questions

[TerryRitchie]

@bplus I doubt using a dynamic array to emulate a true stack will aid with those 2 things, it should be relatively straightforward to implement a faux stack. (a queue and/or a deque on the other hand...). Just need a simple variable to hold the ToS (Top of Stack) and use Redim _Preserve somewhat liberally.

Just curious, where would a stack be handy in QB64 programming?

I created a stack like structure in my Super Megabug game way back in 2010 to store locations of maze endpoints as random mazes are created. But I used a stack structure simply because I was new to QB64 and was familiar with their use when I programmed in Assembler. I could have just as easily used an array.

Perhaps a fixed (static) sized _MEM structure could be used and a stack pointer indicating the current memory location much the same as was done in Assembler. Depending on the pointer use you could create a LIFO or FIFO stack. I think using _REDIM _PRESERVE would be rather slow for something like a stack that is constantly updating.
