PH29544: The Compiler takes a significantly longer amount of elapsed timeand performs a significantly larger amount of I/O.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The Compiler takes a significantly longer amount of time and
  performs a significantly larger amount of I/O than compared to
  Enterprise COBOL V4.2
  
  USERS AFFECTED :
  
  Users of Enterprise COBOL V6.x compiling programs with OFFSET or
  LIST in batch mode where many COBOL programs, with a very large
  total number of lines, are contained in a single dataset member
  and are compiled at once.
  

Local fix

• BYPASS/CIRCUMVENTION:
  No

  ****************************************************************
  In order to allocate memory for preparing the compiler listing,
  the compiler needs to know how many lines of COBOL code are in
  the input file. The compiler determines this by opening the
  input file, jumping to the end, and reading the position in the
  file. When many programs are combined into one source file,
  this
  means jumping to the end of all of them. These file operations,
  while not too expensive on their own, were done multiple times
  for every program in the file (once for each program plus one
  or
  more times per program for the additional compiler-generated
  methods), so the total cost of this I/O was expensive.
  

Problem conclusion

• The compiler was fixed to keep track of the maximum line number
  when it first read the lines for the program being compiled,
  eliminating the need for additional file I/O to find the
  maximum
  number of lines.
