PI73869: CORRECT PROBLEMS WITH SETTING A MAXPCF DEFAULT IN IGYCDOPT USERMOD

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• 4 issues exist surrounding the setting of the MAXPCF=0 value in
  the IGYCDOPT compiler option usermod.
  
  With OPTIMIZE=*2 FIXED or OPTIMIZE=*1 FIXED and no
  specification for MAXPCF in the usermod:
  
  If a customer sets their compiler default usermod to force
  OPT(1/2) on for all programs (not-overridable), the
  Customization Guide says that MAXPCF will be forced to
  MAXPCF(0).
  
  Problem 1) The usermod output (from SIGYMAC(IGYCOPI)) does not
  issue a message stating that MAXPCF(0) is in effect due to
  OPTIMIZE(1/2) FORCED.
  
  Problem 2) With OPT(1/2) forced on, programmers can use any
  value of MAXPCF in their compile that they choose.  The
  compiler output says that this value is used.
  
  
  With OPT(1/2) not specified and MAXPCF=*0 FIXED in the usermod:
  
  Problem 3) If OPT(1/2) is not forced on in the usermod, but
  MAXPCF=0 is forced on, the message generated in the usermod
  output indicating that MAXPCF(0) is in effect is confusing.
  
  Problem 4) If OPT(1/2) is not forced, but MAXPCF(0) is forced
  on, customers can use any value of MAXPCF in their compile that
  they choose and the compiler output does not issue a warning
  message stating that MAXPCF(0) is in effect.

  ****************************************************************
  The compiler was not correctly diagnosing options conflicts
  with the MAXPCF compiler option, both at options processing
  during compilation and at defaults customization.
  

Problem conclusion

• The compiler was modified to enforce the rules for option
  conflict resolution between the OPTIMIZE and MAXPCF options at
  option customization and at compile time.
