This is far too close to IntCode...

Part 1: simple iterative macro
Part 2: batch macro switching nop and jmp one at a time

[T_Willins]

First part was straightforward; second part took a little longer to debug and get the Join correct at the end.

Looking at @jdunkerley79 and @T_Willins solutions, I may have overengineered my macro a bit!

Batch Macro:

In the above batch macro, I used the same iterative macro from part 1, though I was not pleased with the performance results so am looking forward to looking through each of the other solutions to understand how I may have been able to do this more efficiently!

Nested iteratives... as @jdunkerley79 says... IntCode, this year I'm ready for you. Or not.

Not especially happy with my approach as it took a *long* time to solve part 2. Here it is anyway though

Went with a batch macro containing an iterative, to brute force solve the puzzle. However, the fact that I was reading and writing a file every iteration, and using joins made it slooooow.

Closed a container, alteryx crashed, stuck in an endless loop of open alteryx hang on file recovery... Ironic..

 Managed similar to above solutions, iterative to solve, batch to feed in swapped instructions. Definitely could be tidier but got the stars so happy for now...

Similar to above.  Iterative to model the CPU and batch to modify the inputs

Very happy with mine, I managed to use append fields over joins which I think helped with performance and managed to keep tools to a minimum in the first macro. The second macro needed a few extra tools to exit its loop at the right point.
