DATA

DATA is an instruction in Petit Computer that can be used to compactly store numeric and string data.

Official Documentation
Definition of data to be read with READ command. Can include a mix of alphanumeric characters.

Format: Parameters: Data Sequences of strings and numbers to be divided with ','
 * DATA number, number,...
 * DATA "string", "string",...
 * DATA 123,"SAMPLE",...

Returns: None

Oddities
DATA actually does not require strings to have quotes around them.

The above code is completely valid and the strings will be read correctly. Interestingly, the first data "9" can also be read as a number, though "2+4P" and even constants like "2+4" can't be read as a number, even without the quotes. Attempting to READ a string that only contains a number (example: "2") will fail as expected with a type mismatch error.
