Binary Operators¶

List of Binary Operators, in decreasing order of precedence. When operators of equal precedence are adjacent, associativity determines order of evaluation.

SPITBOL and BLOCKS extensions control operator definitions are orthogonal and can be controlled separately.

Char	Defn.	Assoc.	Enabled
= _	assignment	RIGHT	w/ SPITBOL
?	pattern match	LEFT	w/ SPITBOL
&	definable	LEFT
|	alternation	LEFT
#	normal concat	LEFT	w/ BLOCKS
%	vertical concat	LEFT	w/ BLOCKS
sp	concatenation	LEFT
@	definable	LEFT
- +	subtract, add	LEFT
#	definable	LEFT	w/o BLOCKS
*	multiplication	LEFT
%	definable	LEFT	w/o BLOCKS
?	definable	LEFT	w/o SPITBOL
/	division	LEFT
^ **	exponentiation	RIGHT
$ .	match naming	LEFT
~	definable	RIGHT

Unary Operators¶
