When I was testing how stacking strings would work in a Command Block I came to the issue that my game crashed as I pasted in a huge command (Attachment: StringStackingTest_1.txt | 32.9KB) and hit enter...

The reason was, I reached the command block character limit. As I tried it again I saw that it didn't even display the whole command, and as I hit enter it crashed again...

Crash Report File: crash-2014-08-20_18.48.58-client.txt

BUT: The main problem here is not, that the game crashes on reaching the character limit, the main problem is the character limit itself!
The limit is already reached by stacking 14 strings, which needs a command that contains 32,738 backslashes ( \ ).
Stacking 13 strings only needs 16,356 backslashes ( \ ) (Attachment: StringStackingTest_2.txt | 16.8KB).

I do know in terms of programming it is hard to give no limitation on the command length, but it would give us more freedom and possibilities at things like "single command block creation"...

I don't say it is important to remove the limitation, but... You know... Why are minecraft worlds endless? Is that "important"?... Think about that...

If you did, thank you for reading the whole report!
