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:
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.
