i dont use lua much but wanted to know when i used the following code

`jmp <address>` can only jump to addresses within a signed 32-bit displacement relative to RIP. Basically, the address must be within +-2GiB of the `jmp` instruction. It's possible for CE to assemble a pseudoinstruction that can jump farther than 2GiB, but that pseudoinstruction takes up 14 bytes.
That's what the second parameter to `allocateMemory` is for. It is an address CE should allocate memory at (see `VirtualAllocEx`). You should probably call `enumMemoryRegions` to find some free memory nearby, but CE tries to find a free block on its own if the first call to `VirtualAllocEx` fails, so maybe passing the address of the injection point is fine.

If you're calling `autoAssemble` from inside a {$lua} block inside an auto assembler script, you're probably doing something wrong. In this case, you shouldn't be using a {$lua} block at all. Everything could've been done from the AA script itself.
{$lua} blocks can return a string that gets substituted into the AA script in place of the {$lua} block. e.g. you can do `AOBScanUnique(aobstring, '+X')` to only scan through executable memory and pass the result back to the AA script by returning the string `define(foo,<result>)`.

allocateMemory has as 2nd parameter the preferred region to allocate at. If you don't specify it, it will be a random location, likely further than 2GB
