REXX Boolean operators

How do you say AND, OR, and EXCLUSIVE OR in REXX?
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 donít 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.
