Qwertycode

Qwertycode is an esoteric programming language created by nullbyte00, that has a command and operation for every character on a standard QWERTY keyboard, hence its name. However, the only characters that do not have a command associated with them are whitespace and 0-9, which for obvious reasons can not be used. Qwertycode is similar to brainfuck in that it makes use of a tape, but has many more commands and supports subroutines, looping, conditionals, and gotos.

Commands

Qwertycode has over 50 commands and operators represented by a single character. They are:

Command	Description
A	Assigns a value to a byte
B	Value of current byte
C	Assigns a constant value to a byte
D	Value of previous byte
E	Exits the program
F	Sets all bytes to 0
G	Greater than
H	Outputs the ASCII value of all bytes
I	Outputs int value of all bytes
J	Change the pointer to the specified value
K	Stops the program, and returns an error message
L	Less than
M	Multiplies all bytes by 2
N	Divides all bytes by 2
O	Sorts the bytes from lowest to highest
P	Pauses the program
Q	Total number of bytes
R	Random value between 0 and 255
S	Stops the program
T	Value of next byte
U	Increase all bytes by 1
V	Decrease all bytes by 1
W	Pauses for a specified number of microseconds
X	Performs either E, H, K, M, N, O, P, S, U, V, or Y at random
Y	Sorts all bytes by random
Z	Value of the pointer
~	Defines a subroutine
`	Outputs int value of a byte
!	Inequality comparison
@	Label
#...#(n)	Everything in between the #'s gets repeated n times
$	Call to subroutine
%	Square roots a byte
^	Squares a byte
&	Greater than or equal to
|	Less than or equal to
*	Multiplies a byte
_	Prints a new line
-	Decrements a byte
+	Increments a byte
=	Equality comparison
:	Goto
;	Accepts input in form of an int, then stores in a byte
"..."	Conditional, where everything in between the "'s is the condition
'...'	Comment, where everything in between the 's is a comment
<	Decrements the pointer
>	Increments the pointer
,	Accepts input in form of ASCII, then stores in a byte
.	Outputs ASCII value of a byte
?	Begins conditional
/	Divides a byte by 2
\	True if two values are within a range of 1
(...)	Group (many commands need their arguments within a group)
[...]	Index
{...}	Conditional and subroutine block

Although all commands are listed in uppercase, Qwertycode is case-insensitive so lowercase is alright. Whitespace is also ignored, but preferred for readability.

How To

This section will explain how to do simple tasks, such as declaring subroutines.

Assign a value to a byte

When assigning a value to a byte, you simply list the byte you want to assign the value to, followed by an A or C (if you want it constant), then the int value in a group. Here are three examples:

This assigns 65 to the current byte:

BA(65)

This assigns 5 to the 8th byte:

B[7]A(5)

This assigns a random value to the current byte:

BA(R)

Output the value of a byte

To output the value of a byte, you simple list the byte who's value you want outputted, then either a . or a ` (dpending on whether you want the int value or the ASCII value outputted). Here are two examples:

This assigns 65 to the current byte, and outputs its ASCII value (which is A):

BA(65)
B.

This assigns 66 to the 2nd byte, and outputs its int value (which is 66):

B[1]A(66)
B[1]`

Use subroutines

To declare a subroutine, you use the ~ followed by a group of numbers which is the name of the subroutine.

This declares a subroutine called 2:

~(2)

To then put code inside the subroutine, the group is followed by an opening curly, your code, then a closing curly. Example:

~(2){
UB.
}

Finally, to make a call to a subroutine, you use the $, followed by a group containing the name of your subroutine. Example:

~(2){
UB.
}
$(2)

Create a loop

To create a loop, every command you want looped goes between two #s, then a group saying how many times it should loop.

This will output A 10 times:

BA(65)
#B.#(10)

Use gotos

To use a goto, you must first create a label by using the @ character, followed by a group of numbers, which is the name.

This will create a label named 1:

@(1)

To jump, or goto, that label, use the : character followed by a group containing the name of the label. Example:

@(1)'some code goes here':(1)

This would of course create an infinite loop however.

Use conditionals

To use conditionals, you use the ? character followed by a condition surrounded in "s. Example:

?"B=(10)"

To then execute code if the condition is true, you use a pair of curly brackets. Example:

?"B=(10)"{UB.}

There are a limited amount of functions you can perform in a condition. You can check for equality, inequality, etc. See the list of commands for everything you can use.
