2char

This is still a work in progress. It may be changed in the future.

This article is not detailed enough and needs to be expanded. Please help us by adding some more information.

2char is an esolang by User:7rigs where good or/and useful programs have a code with minimum 2 symbols, but so limited.

2char works like this: 1 character: sets mode and 2 character: mode dependent command

mode setting commands are in higher case, and mode dependent commands are in lower.
