PH45895: LARGE PROGRAMS WITH HUNDREDS OF COPYBOOKS MAY EXPERIENCE IMPROPER COPYBOOK EXPANSION FOR USS COMPILES.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Very large programs containing hundreds of copybooks may
  experience improper copybook expansion for USS compiles,
  including compiles done with the RTC and the Dependency Based
  Build compilation tools.
  
  The symptoms may include seeing garbage characters in place of
  a line from a copybook or seeing lines that are missing from a
  copybook.  This typically results in compiler errors similar to:
  
  IGYPS0027-S Non-COBOL character(s) were found starting with " "
  in column nn.  The characters were discarded.
  
  IGYPS0007-E An alphanumeric literal was not properly continued.
  The end of the literal was assumed on the last source line.
  
  IGYPS2121-S  XYZ was not defined as a data-name. The statement
  was discarded.
  

Local fix

• Compile in TSO.

  The compiler was not properly caching all of the contents of the
  copybook files when many hundreds or thousands of COPY
  statements appeared in the source program.
  

Problem conclusion

• The compiler has been changed so that it does proper accounting
  and caching for all of the many hundreds or thousands of copy
  book files and their contents.
