Question

What doesn the Σ command do? The instruction table says nothing about that. --None1 08:14, 30 August 2024 (UTC)

Judging from its use in the examples I'd guess the same as its lowercase counterpart (as a standard symbol for user-defined statements). -PkmnQ (talk) 13:16, 30 August 2024 (UTC)

Its lowercase counterpart has no action in table as well. --None1 03:04, 31 August 2024 (UTC)

Interesting subset

I'm sort of interested by what happens if you defined a language like this:

• For all Unicode characters ς other than ιχθυΙΧΘΥ, there exist two commands in the language defined as Ιςχ and ς itself
• The only other command is defined as ΧιΘ

I might define it as a separate esolang, but if not, I'd at least like to mention it here. --PkmnQ (talk) 09:42, 21 September 2024 (UTC)

I've worked out a looping counter in this subset and am currently working on a Collatz program, so I think there's a good chance this subset is TC on its own. Here's the looping counter (assuming * outputs an asterisk and τ outputs a newline: --PkmnQ (talk) 10:07, 24 September 2024 (UTC)
