QUESTION: 20
A programmer has been asked to write a program that tests a variable, X, and writes out A, B, C
or D if X is 0, 1, 2 or 3 respectively and writes out E when X has none of those values. Which of
the following programs represents the best practice using IF or SELECT statements?

A. SUB1: PROC( X );DCL X FIXED UNSIGNED;IF X = 0 THENPUT SKIP LIST ( 'A');ELSEIF X
= 1 THENPUT SKIP LIST ( 'B');ELSEIF X = 2 THENPUT SKIP LIST ( 'C');ELSEIF X = 3
THENPUT SKIP LIST ( 'D');ELSEPUT SKIP LIST ( 'E');END;
B. SUB2: PROC ( X );DCL X FIXED UNSIGNED;IF X < 2 THENIF X = 0 THENPUT SKIP LIST (
'A');ELSEPUT SKIP LIST ( 'B');ELSEIF X = 2 THENPUT SKIP LIST ( 'C');ELSEIF X = 3
THENPUT SKIP LIST ( 'D');ELSEPUT SKIP LIST ( 'E');END;
C. SUB3: PROC( X ); DCL X FIXED UNSIGNED;SELECT;WHEN ( X = 0 )PUT SKIP LIST (
'A');WHEN( X = 1 )PUT SKIP LIST ( 'B');WHEN( X = 2 )PUT SKIP LIST ( 'C');WHEN( X = 3
)PUT SKIP LIST ( 'D');OTHERWISEPUT SKIP LIST ( 'E');END;END;
D. SUB4: PROC( X ); DCL X FIXED UNSIGNED;SELECT ( X );WHEN ( 0 )PUT SKIP LIST (
'A');WHEN ( 1 )PUT SKIP LIST ( 'B');WHEN ( 2 )PUT SKIP LIST ( 'C');WHEN ( 3 )PUT SKIP
LIST ( 'D');OTHERWISEPUT SKIP LIST ( 'E');END;END;

Answer(s): D

A. PROC( RC );
DCL RC FIXED BIN(31);
IF RC = 0 ! 4 THEN
B. IF RC = (0 ! 4) THEN
C. IF RC = 0 ! RC = 4 THEN
D. IF BIT(RC = 0 ! 4 ) THEN
E. IF BOOL(RC = 0, 4, '0111'B) THEN

Answer(s): B
