GotoFuck

GotoFuck (also known as GotoF, GotoF***) is a brainfuck derivative by VilgotanL, It is identical to brainfuck except that uses a conditional goto instead of the regular while-loop.

Instructions

+	Increment the cell at the pointer
-	Decrement the cell at the pointer
>	Move the pointer right
<	Move the pointer left
.	Print the value of the cell at the pointer as an ascii character
,	Take one character of input and place its ASCII code into the cell at the pointer, 0 on EOF
:n	If the value of the cell at the pointer is 0, goto the line n with line numbers starting at 1, if n is omitted, invalid, or out of range, the program ends if the cell at the pointer is 0

Any other instructions are ignored.

Computational class

GotoFuck is Turing-complete since brainfuck can be transpiled to it using the following translation table:

Brainfuck	GotoFuck
>	>>
<	<<
[	:n> < where n is the line number after the transpiled code of the matching ]
]	:after>:n where after is the line number after this line, and where n is the line number after the transpiled code of the matching [, (the line with the <)

All other instructions are the same.

This can be shown in action in this transpiler.
