Free
- This is still a work in progress. It may be changed in the future.
Free is a joke esoteric programming language created as a parody language where the syntax is based entirely on digits and a few special symbols. The idea behind Free is that "syntax is price": every command corresponds to a digit, making the source code look like a sequence of numbers rather than text.
Overview
The language operates with two internal variables:
- The Accumulator, which is used mainly for output operations (printing numbers or ASCII characters).
- The Accumulator2, which is used for controlling program flow such as conditional checks and loops.
A Free program is simply a chain of digits and a few non-digit symbols. Execution starts when the $ command is encountered.
Commands:
| Command | Description |
|---|---|
$
|
Marks the start of program execution. |
1
|
Increment the Accumulator by 1. |
0
|
Decrement the Accumulator by 1. |
2
|
Output the current value of the Accumulator as an ASCII character. |
3
|
Output the current value of the Accumulator as a number. |
4
|
If Accumulator2 is equal to 0, jump forward to the next 5.
|
5
|
If Accumulator2 is not equal to 0, jump back to the previous 4.
|
6
|
Reset both Accumulator and Accumulator2 to zero. |
7
|
If Accumulator2 equals the most recently executed digit command, execute the next command. Otherwise, skip it. |
8
|
Increment the Accumulator2 by 1. |
9
|
Decrement the Accumulator2 by 1. |
,
|
Begin a comment block. Everything after this command is ignored until the next ..
|
.
|
End a comment block. |

Examples
Output "1"
A trivial program that outputs the number 1:
$13
Output "A"
A program that outputs the letter A (ASCII code 65):
$111111111111111111111111111111111111111111111111111111111111111111112
Status
The language was created as a parody and has no practical use. Its main feature is the deliberately absurd restriction of "everything is digits", making code appear like meaningless numbers.
