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.

I use LIFO stacks for return lines from GoSubs in my interpreter and use LIFO stack when converting a recursive routine to a manual routine not using built in recursion of QB64.

@grymmjack I got paged twice by Terry's post above?
