Simple IF - processing on Y only N IF AMT > 5000 Y AMT x 10 = ANS if amt > 5000 ans = amt * 10 end if

Simple IF - processing on Y or N N ANS = AMT x 5 if amt > 5000 ans = amt * 10 else ans = amt * 5 end if IF AMT > 5000 Y ANS= AMT x 10 In this example, if the AMT is greater than 5000 then we want to multiply AMT by 10 and store the answer in ANS. If the AMT is not greater than 5000 then we want to multiply AMT by 5 and store the answer in ANS.

AND relationship N Y IF INVCD = “A” N IF AMT > 5000 Y MOVE “OKAY” TO MSG if invcd = “A” if amt > 5000 move “OKAY to msg end if Both statements must be true for the msg to receive the word OKAY. If either statement is false, no processing is done.

AND relationship N IF INVCD = “A” N Y IF AMT > 5000 Y MOVE “OKAY” TO MSG if invcd = “A” if amt > 5000 move “OKAY to msg end if if invcd = “A” and amt > 5000 move “OKAY” t 0 msg end if

AND relationship N Y IF INVCD = “A” MOVE “PROBLEM” TO MSG N IF AMT > 5000 MOVE “PROBLEM” TO MSG if invcd = “A” if amt > 5000 move “OKAY to msg else move “PROBLEM” to msg end if Y MOVE “OKAY” TO MSG if invcd = “A” and amt > 5000 move “OKAY” to msg else move “PROBLEM” to msg end if

OR relationship N IF INVCD = “A” Y MOVE “OKAY” TO MSG N IF AMT > 5000 Y MOVE “OKAY” TO MSG One or the other of the if questions must be true for OKAY to be moved to msg. if invcd = “A” move “OKAY” to msg else if amt > 5000 move “OKAY” to msg end if

In boolean logic AND gets resolved before OR. That means if we did not have the parenthesis, it would treat this like invcd = A and amtfst > 500 or just amtsnd > 200. Y Continue below N IF AMTSND > 200 Y MOVE “OKAY” TO MSG We want the logic to be invcd = A and either amtfst > 500 or amtsnd >200. To do this, we need to change the order of operation so that the two things in the or relationship are grouped together. We do this by using parenthesis.
