APAR status

Error description

• Headline/Abstract
  ***************************************************************
  Rational Developer for System z (RDz) Content-assist response
  time increases when adding variables to a COBOL 'USING' list
  
  APAR Error Description
  ***************************************************************
  Rational Developer for System z - RDz - v7.6.3
  
  The response time when using the content assist to add variables
  to the USING list increases with the number of variables already
  on this USING list.
  
  For instance, use the following COBOL instruction:
  
  CALL 'ANYPGM' USING
       FIELD-1
       FIELD-2
  END-CALL.
  
  Then, use the content assist to add a new variable to the USING
  list (FIELD-3, FIELD-4,...). After each added variable to that
  list, the response time will increase, until an OutOfMemory
  error window pops-up.
  ***************************************************************
  Local fix:
  None

Problem summary

• ****************************************************************
  *
  USERS AFFECTED:
  RD/z users who use content assist in COBOL programs to add
  variables to a USING clause in a CALL statement.
  ****************************************************************
  *
  PROBLEM DESCRIPTION:
  When adding variables to a USING clause in a CALL statement
  in a COBOL program, the time to provide proposals increases with
  each added variable until eventually an OutOfMemory error window
  is displayed.
  

Problem conclusion

• ************************************************************
  PROBLEM RESOLUTION:
  When variables are added to a USING clause in a CALL
  statement, the content assist response time does not increase
  rapidly with each added variable, and an OutOfMemory error
  window is not displayed.
