REXX Boolean operators


	&		AND                              

|		OR: either one, or both 
		
	&& 		Exclusive OR: 
			one is true, not both.      
		




& (AND)
	IF PAY_GRADE = 11 & NAME = "ELLEN"
	THEN SALARY = SALARY * 2

| (OR)
	IF PAY_GRADE = 11 | PAY_GRADE = 12 
	THEN SALARY = SALARY * 1.5

&& (Exclusive OR)
	IF PAY_GRADE = 11 && EMPLOY_STATUS = "RETIRED"
	THEN NOP
	ELSE SAY "INPUT DATA ERROR"


The English words AND/OR don’t work. They may not produce a syntax error but will produce the wrong results.
	IF PAY_GRADE = 11 AND NAME = "ELLEN"	
	THEN SALARY = SALARY * 2
Will compare PAY_GRADE to the character string 11 AND NAME = "ELLEN" and the results will be wrong.
