"Infinite" Procedural Generate Game Possible?

as long as you "unload" things (destroy) you don't need (i.e. tiles outside screen, enemies too far etc.)
the only limit I can see is you saving medium

I guess the array has 256 GB memory limit,
I think you can store a (rough) maximum in (about) the order of some million entries (cells)

but for optimal performances you'd better stay well below those numbers
parsing an array with very big indices can be slow and save/load times much longer

so if you need more, to stay on the safe side,
you could simply use smaller but multiple array save files for your "sections"
and clear/load them on need
(like splitting your world in grids of, say, 1000x1000 cells (sectorX0Y0),
when you get on the 1001th horizontal cell clear the array and set your file to sectorX1Y0.arr)
making things almost infinite
(limit would be your hard drive capacity for storing all this array stuff XD)

then you would have to think if using multiple arrays (3 would do) to parse your sectors outer "edges" in real time as you approach a different sector

I think it'd be tough especially if you want the player to be able to return to the older areas (which of course you would I would think).
If you were going floor by floor where the player couldn't return to them afterwards you could have the thing go all night and day

Infinite is not possible because you'll run out of memory to story the infinite world. Unless you're going to randomly generate sections that when you return to they are 're-randomly generated', but that is not really an infinite world but a random world. However you can make 'very big' worlds, given that computers have a rather large memory bank.

The problem you're asking is also a generally philosophical one, can we simulate our own universe inside our universe? Even if we use an atom-per-atom system to store the position every atom in our universe, we would need to construct a universe the size of our own to store our simulation.

So if you're looking to create an infinite model inside the finite space of our universe, you're not going to have enough binary 'on-off' switches to do so, noting that a binary 'on-off' switch takes up more than 1 atom. If you were to acquire enough binary switches, you would be constructing another universe infinitely larger than our own to store your 'infinite game'.
