  • Closed as program error.

Error description

  • USERS AFFECTED: Users of Enterprise COBOL Vx.x compiling
    programs at OPT(0) with an extremely large
    number of data items with VALUE clauses, or
    compiling programs at OPT(1|2) with a large
    number of filler items with VALUE clauses.
    
    RECOMMENDATION TO CUSTOMER: Apply provided fix.
    
    PROBLEM SUMMARY: Register allocation was spending too much time
    selecting the
    optimal register in programs that contain a very large number
    of data items with VALUE clauses.  In addition, at OPT(1|2),
    the compiler was processing filler items with VALUE clauses in
    a non-optimal way.
    
    CONCLUSION: The compiler was updated to select an optimal
    register faster
    and to improve the processing of filler items with VALUE
    clauses at OPT(1|2).
    

Local fix

  • WORKAROUND/CIRCUMVENTION: If you experience slow compile times
    when compiling a program
    with a large number of non-filler data items with VALUE clauses
    at OPT(0), try compiling with OPT(1) or OPT(2).
