abc:	declare label abc. Label names can contain lowercase letters and digits
abc^	jump to label abc if cell pointed by top stack element is zero
abc@	jump to label abc if cell pointed by top stack element is nonzero
,	set current cell to next input byte
.	output current cell as ASCII character
"	duplicate stack element
*	push zero to the stack
&	reverse stack
