문제 #1

PL/I programs which have been written under Intel architecture are now to be recompiled and run on the
mainframe. What will happen to the programs during compilation and execution?

A. They will not run correctly because the byte order on mainframe is bigendian.
B. They can be recompiled unchanged and will run correctly.
C. They may have to be changed before they run correctly on the mainframe.
D. They will not compile correctly on mainframe because ASCII has no NOT sign.

문제 #2

The following function converts a character string to uppercase. What is the best way to improve the
performance?
SET_TO_UPPERCASE: PROC(CHARSTR) RETURNS (CHAR(120) VARYING);
DCL CHARSTR CHAR(120) VARYING;
DCL UCCHAR(26) INIT('ASCDEFGHIJKLMNOPQRSTUVWXYZ');
DCL LCCHAR(26) INlT('abcdefghijkImnopqrstuvxy'z');
DCL RCHAR(120) VARYING INIT(");
R = TRANSLATE(CHARSTR,UC,LC);
RETURN(R);
END SET_TO_UPPERCASE;

A. Declare variables UC and LC as STATIC.
B. Use VALUE on the declares for UC and LC.
C. RETURN(TRANSLATE(CHARSTR,UC,LC)) to avoid the unnecessary assignment to R.
D. Use the UPPERCASE function instead of SET_TO_UPPERCASE.

문제 #3

The following structure is used when writing a file on Intel architecture which is sent to the mainframe:
DCL 1 A,
2 B FIXED BIN(31),
2 C CHAR (100) VAR,
2 D FIXED BIN(31);
How must this structure be declared on the mainframe if the file is to be read correctly?

A. DCL1 A,
2 B FIXED BIN(31) BIGENDIAN, 2 C CHAR (100) VAR BIGENDIAN, 2 D CHAR (10);
B. DCL1 A,
2 B FIXED BIN(31) LITTLEENDIAN,
2 C CHAR (100) VAR,
2 D CHAR (10);
C. D CL 1 A,
2 B FIXED BIN(31) BIGENDIAN,
2 C CHAR (100) VAR,
2 D CHAR (10);
D. DCL1 A,
2 B FIXED BIN(31) LITTLEENDIAN,
2 C CHAR (100) VAR LITTLEENDIAN,
2 D CHAR (10);

문제 #4

A given PL/I program has a big nesting depth. Which of the following measures will help to reduce the
nesting depth in most cases?

A. Avoiding OTHER clauses
B. Using DO-WHILE as the only loop technique
C. Avoiding ELSE clauses
D. Using SELECT constructs instead of If-THEN-ELSE

문제 #5

Which compiler option causes the compiler to flag any IF, WHILE, UNTIL and WHEN clauses that do not
have the attributes BIT(1) NONVARYING?

A. RULES(NOLAXWHILE)
B. RULES(NOLAXWHEN)
C. RULES(NOLAXUNTIL)
D. RULES(NOLAXIF)
