LCCBED

This article is not detailed enough and needs to be expanded. Please help us by adding some more information.

LCCBED stands for "Letter Command Brainf*** Enhanced Derivative". It was created by iamn00b in 2021. Its goal was simple: to make a slightly more confusing yet wonderful variation of Brainf***. As of the time of writing (September 20, 2021), there are no implementations of LCCBED available yet.

Language overview

Overall, LCCBED programs work in a similar way to Brainf***: Data is stored in cells, and the program moves the cell pointer around and increments/decrements the cell's value. The main difference is that while Brainf*** uses symbols (<>+-[],.), LCCBED uses letters (explained in the next section). Another notable difference is that LCCBED also has several "ease-of-use" commands, as well as arguments ("()") to ease some of the load off of the programmer.

Instructions

Command	Description
f	Moves the pointer forward (">")
b	Moves the pointer backwards ("<")
p	Increments the value of the active cell ("+")
m	Decrements the value of the active cell ("-")
w	Starts a while loop ("["). If called without arguments, it will use the default argument "while active cell is not 0".
e	Ends the while loop ("]"). Note that each "w" must have a corresponding "e", unbalanced w's and e's will cause an error.
()	Arguments for a command (e.g. p(10) will increment the active cell's value by 10, w(<20) ... e will repeat the actions until the active cell's value is 20.
r	References a cell with an argument of position relative to active cell and returns its value (e.g. p(10) f r(-1) will set Cell 2's value to 10).
a	Similar to r, however, it uses absolute references (ref. point is the very first cell). For example, p(5) f a(1) will set Cell 2's value to 5.
g	This command acts as a goto that takes in a number for an absolute reference. For example, p(23) f p(18) g(1) will move the pointer back to the very first cell.
o	This command outputs the active cell's value. It has 2 modes, ASCII and number.
i	This command takes in an input's ASCII value and assigns it to a cell. If the input has multiple digits, it will assign the value of each digit to a different cell.
c	Converts a cell's "mode" from ASCII to number vice versa, depending on whatever was the cell's mode was before conversion. By default, all cells start out in ASCII mode.
'	Text in quotes are comments.
w0e	Infinite loop with an invalid command, causes the program to hang and terminate.

Simple single-digit addition

ic 'accepts first input, converts it into a number'
f 'moves pointer forward'
ic 'accepts second input, converts it into a number'
b 'moves back to first cell to prepare while loop'
w 'while cell 1 is not 0'
ff 'move pointer to cell 3'
p 'add 1 to cell 3'
b 'back to cell 2'
w 'while cell 2 is not zero'
f 'go to cell 3'
p 'add 1 to cell 3'
b 'back to cell 2'
m 'reduce cell 2 by 1'
e 'jump past this when cell 2 is 0'
b 'back to cell 1'
m 'reduce cell 1 by 1'
e 'jump past this when cell 1 is 0
ff 'go to cell 3'
co 'convert it into number mode, then output its value'
'example: input 2 & 3, output 5'
