PM56359: RDZ 8031 PLI Real Time Syntax check marks correct free parm in error

Rational Developer for System z 8.5

APAR status

• Closed as program error.

Error description

• Create a pl1 program with the following source :
  
   dcl (nodePtr) pointer,
  
       1 dataNodeType based(nodePtr),
  
          3 areal char(100);
  
   dcl LinkListHeadPtr pointer;
  
   dcl 1 myLinkedList based(LinkListHeadPtr),
  
        3 next ptr,
  
        3 dataNode ptr;
  
  
  
   allocate myLinkedList;
  
   LinkListHeadPtr-?myLinkedList.next = null();
  
   allocate dataNodeType;
  
   LinkListHeadPtr-?myLinkedList.dataNode = nodePtr;
  
   free LinkListHeadPtr-?myLinkedList.dataNode-?dataNodeType;
  
   free LinkListHeadPtr-?myLinkedList;
  
  
  
  Notice that the first 'free' statement is marked with an error
  while second is not.  Both are valid and accepted by local
  syntax check and compilers.  This can be reproduced with a local
  PLI source file.

Problem summary

• USERS AFFECTED:
  RD/z users who use RD/z to edit PL/I programs with free
  statements with complicated pointer expressions.
  ****************************************************************
  *
  PROBLEM DESCRIPTION:
  RD/z reported free statements with complicated pointer
  expressions in PL/I programs with warning annotations, even
  though the syntax was correct, when the program was edited.
  

Problem conclusion

• RD/z correctly handles free statements with complicated pointer
  expressions in PL/I programs when they are edited.
