• Question 91:

  In the following example, what value will be written to SYSPRINT, if anything, by the PUT statement in PGM_A?

  PGM_A: PROC;

  DCL INPARM CHAR (12) INIT('FIRST CALL? `);

  DCL P_OUT PTR;

  DCL OUTPARM CHAR (10) BASED (P_OUT);

  DCL PGM_B ENTRY (CHAR(12),PTR) EXTEPNAL;

  CALL PGM_B (INPARM,P_OUT);

  IF OUTPARM = `YES' THEN

  DO;

  INPARM = `FOLLOW ON';

  CALL PGM_B (INPARM,P_OUT);

  END;

  ELSE

  DO;

  INPARM = `NORMAL CALL';

  CALL PGM_B (INPARM,P_OUT);

  END;

  PUT SKIP LIST(OUTPARM);

  END;

  PGM_B: PROC(INPARM,P_OUT);

  DCL INPARM CHAR (12);

• Question 96:

  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');

  B. The number of records read from the GSAM dataset and the number of IMS segmentschanged.
  C. The number of records read from the GSAM dataset, the key of the last record read from the GSAM dataset and the key of the last IMS segment updated.
  D. The key of the last IMS segment changed and the number of segments changed.
  B. The number of records read from the GSAM dataset and the number of IMS segmentschanged.
