Brainfuck NEVER CLEAR

BRAINFUCK NEVER CLEAR (BFNC) is a programming language designed to be part of a series of other esoteric programming languages turned into awfully disgusting tools to use.

Commands

Command	Description
+	Adds 2 to the current cell value.
-	Takes away 1 from the current cell value.
<	Moves pointer right, unless its position in the line of code is even, then moves left.
>	Moves pointer left, unless position is divisible by 3 (moves right). If position is divisible by 4, halts.
.	Outputs current cell value as a number. Halts if the line number is divisible by 7 (moves right instead), or if the previous executed character was +.
,	Inputs a value and adds it to the current cell.
[	Standard loop start, except it halts immediately if the current cell value is 10.
]	Standard loop end, except it halts immediately if the current cell value is 10.

Examples

Outputting numbers 72 and 73

Because of the positional restrictions and the immediate halt if . follows +, code must be padded or written vertically (line index 1):
