130 ;;Quote: recall(p,x) is for simplifying program design; like recursion
131 ;;Quote: would like predicates to test if an action is possible; e.g., 'if can suspend process p ...'
131 ;;Quote: 'leave(p,v)' terminates most recent activation of p and returns v as its value
131 ;;Quote: recall(p,x) is equivalent to leave(p,p(x)); it replaces the most recent activation with a new one QuoteRef: thimH2_1980 ;;131 "'Leave can be used for handling errors detected in low level procedures
132 ;;Quote: terminate a procedure abnormally by calling an error handler; can recall it or return an appropriate result
132 ;;Quote: continually recalls the expression parser until the user correctly modifies the expression
133 ;;Quote: at a breakpoint, a user can 'recall' a procedure with new parameters, continue, or 'leave' with a given result
