Remove Line Numbers (you can use RLN for short), is a joke esolang created by User:None1.
Syntax
RLN's syntax is:
<line-number><spaces><text>
Line number must be a positive decimal integer, and represents exactly the line number of the text. For example:
1 a
is correct, but
-1 a
0x0f a
4.5 a
2 a
(0110110001)[2] a
5+1 a
4^2 a
sin(90deg) a
are all incorrect.
Note that text can be empty.
Execution
When running, the interpreter/compiled executable simply removes all the line numbers from its source code and prints all the text.
Example Programs
Hello World:
1 Hello World!
99 bottles of beers:
1 99 bottles of beer on the wall, 99 bottles of beer. Take one down and pass it around, 98 bottles of beer on the wall. 1 98 bottles of beer on the wall, 98 bottles of beer.
