These action codes are effectively mathematical, logical-test or assignment operators.
Such operators are:
- - (i.e. subtraction)
- -= (i.e. decrement)
- != (i.e. value inequality)
- ... (i.e. range)
- (!$AttributeName) (i.e. a short form test for no value)
- * (i.e. multiplication)
- / (i.e. division)
- & (i.e. query logical AND join)
- &= (i.e. logical AND assignment)
- + (i.e. addition)
- + (i.e. string concatenation)
- += (i.e. increment)
- < (i.e. less than)
- <= (i.e. less than or equal to)
- = (i.e. value assignment)
- == (i.e. value equality)
- > (i.e. greater than)
- >= (i.e. greater than or equal to)
- | (i.e. query logical OR join)
- |= (i.e. logical OR assignment)
- $AttributeName (i.e. a short form test for value)
- changed([scope])
- String.sentences()
- while(condition){}
