NAME
       snobol4op - SNOBOL4 operators

DESCRIPTION
       All  SNOBOL4  operators	can  be	redefined with OPSYN().	 These are the
       default assignments.

       The following operator character	sequences are permitted	and  represent
       a cross between PDP-10 Macro SNOBOL4, SITBOL and	Catspaw	SPITBOL	usage:

   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
       Char	 Defn.
       \	 negation
       ?	 interrogation
       $	 indirect reference
       .	 none
       !	 none
       %	 none
       *	 unevaluated expression
       /	 none
       #	 none
       +	 positive
       -	 negative
       @	 cursor	position assignment
       |	 none
       &	 keyword
