# [dc] (GNU), 2 distinct characters (`z`, `P`), 134660653084537 bytes

The behavior of `P` on number is a GNU extension.

(can't post code)

Anyway, this is the generator program: [Try it online!][TIO-kktqnsj2]

You can verify manually that for some smaller text (such as `abca`) it produces the correct output. It will only actually try to construct the program if the resulting program size does not exceed \$2^{16}\$ (configurable in the program)

Assuming that the actual [dc] implementation doesn't have any problem with having about that many numbers on the stack.

I came up with the idea when someone [mentioned in chat](https://chat.stackexchange.com/transcript/message/56978380#56978380) that it's possible to solve the challenge with 2 distinct bytes.
