PH23443: THE INITCHECK COMPILER OPTION INCORRECTLY FLAGS A LINKAGE DATA ITEM THAT IS MOVED TO THE LOCAL-STORAGE SECTION

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• INITCHECK is incorrectly catching (twice) a move from the
  LINKAGE section to the LOCAL-STORAGE section and reporting that
  it is uninitialized.
  
  Sample Code:
  
  000001              IDENTIFICATION DIVISION.
  000002              PROGRAM-ID. X80573.
  000003              DATA DIVISION.
  000004              LOCAL-STORAGE SECTION.
  000005              01 WORKING-FIELDS.
  000006                 10 W-OPTION               PIC X(4).
  000007                     88 W-UPDATE            VALUE 'UPDT'.
  000008                     88 W-LIST              VALUE 'LIST'.
  000009              LINKAGE SECTION.
  000010              01 LINKAGE-FIELDS.
  000011                05 LK-OPTION    PIC X(4).
  000012              PROCEDURE DIVISION USING LINKAGE-FIELDS.
  000013              AA000-HOUSEKEEPING SECTION.
  000014                  MOVE LK-OPTION TO W-OPTION.
  000015                  GOBACK.
  
  The compiler returns:
  14 IGYCB7311-W The data item 'W-OPTION' may be used at this
                 statement before it is set.
                 Same message on line:   14
  

Local fix

• Compile with NOINITCHECK.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL V6.2 compiling     *
  *                 programs with INITCHECK that MOVE data from  *
  *                 a sender in the LINKAGE SECTION to a         *
  *                 receiver in WORKING-STORAGE or               *
  *                 LOCAL-STORAGE where the receiver is          *
  *                 uninitialized before the MOVE.               *
  ****************************************************************
  * PROBLEM DESCRIPTION: The compiler incorrectly issues message *
  *                      MSGIGYCB7311-W The data item 'XXXXX'    *
  *                      may be used at this statement before    *
  *                      it is set. for the receiver.            *
  ****************************************************************
  * RECOMMENDATION: Apply the provided PTF.                      *
  ****************************************************************
  The compiler's internal state incorrectly indicated that
  receivers of a MOVE statement with a LINKAGE SECTION sender
  should be considered when determining which data items were not
  initialized.
  

Problem conclusion

• The compiler was corrected to ignore receivers of MOVE
  statements with LINKAGE SECTION senders when determining which
  data items were not initialized.
