ABSTRACT OF PROBLEM
___________________
 
Remove  user-modifiable  code  from  the  CISO  library and move
OBJONLY segment CFTOK40 from the  COMX  library  into  the  CISO
library.
 
 
                                                                            1
 
 
 
 
 
 
 
 
 
 

COMMENTS ON PROBLEM
___________________
 
Customers  can  alter  and  compile user-modifiable code in some
non-OBJONLY members of the CISO library.  A customer can prelink
and link the CISO library using TPF's OBJONLY object modules and
the customer's modified object modules as long as  the  customer
uses  an OS/390 prelinker and linkage-editor that is equal to or
higher than the OS/390 compiler level that TPF used  to  compile
the  CISO  OBJONLY members. There is a problem, however, if  the
customer's  OS/390 prelinker and linkage-editor is  at  a  lower
level  than  TPF's  OS/390  level.  Unpredictable  prelinker and
linkage-editor errors may  occur.  To  eliminate  this  problem,
there is a need to move the user-modifiable code out of the CISO
library.  The  customer can then compile, prelink, and link-edit
the user-modifiable code  without  any  conflicts  with  OBJONLY
object  modules.  There  is also a need to move OBJONLY segments
from the COMX library to the CISO library so that user-  modifi-
able  code  can  remain  in  the  COMX  library and compilation,
prelink, and link-editing  of  COMX  can  also  be  carried  out
without conflict.
 

SOLUTION
________
 
o   User-modifiable  code  was moved out of the CISO library and
    segments clnm.asm, csnm.asm, cmlm.c, and usud.c were created
    to hold the user-modifiable code.
 
o   Separate DLMs for were created for each of these segments.
 
o   OBJONLY segment CFTOK was moved from the COMX  library  into
    the CISO library.
 
This  APAR  removes  all  user-modifiable code from CISO and all
OBJONLY code from COMX.
 
DEPENDENCIES
____________
 
Related Segments Affected By This APAR.
_______________________________________
 
Segments to be assembled or compiled:
None.
 
Segments to be link-edited:
CISO40, COMX40, CMLM40, CSNM40, CLNM40, USUD40.
 
Load Modules to be loaded:
CISO40, COMX40, CMLM40, CSNM40, CLNM40, USUD40, CDCO40, CDCP40.
 
Migration Considerations
========================
As follows:
 
These instructions are nonstandard because customers will not have
access to migration documentation until they have access to PUT 15
documentation. Therefore, the following migration considerations should
provide sufficient instruction to apply this migration.
 
o    CMLM40 is the user-modifiable object in the CMLM load module.
    It maps the locale internal name to the locale module name and it
    takes the place of the CLMODN object that has been removed from the
    CISO library.
 
o   CLNM40 is the user-modifiable object in the CLNM load module. It
    maps the locale external name to the locale internal name and it
    takes the place of the CLCNM object that has been removed from the
    CISO library.
 
o   CSNM40 is the user-modifiable object in the CSNM load module. It
    contains the code page name table and takes the place of the CSNAM
    object that has been removed from the CISO library.
 
o   USUD40 is the user-modifiable object in the USUD load module. It
    contains the function is_dll_user_ss_shared that was removed from
    segment CSSDLL40 in the CISO library.
 
o   Make two stubs, CMLM and USUD, before linking COMX.
 
 
o   Modules CDCO and CDCP must be reloaded. They have been link-edited
    again to take on changes made to CISO and COMX. These load modules
    are provided with this APAR pre-linked. According to instructions
    given with APAR PJ27095, the customer will not be required to
    rebuild these load modules.
 
 NOTE: Any prior modifications made to CLMODN, CLCNM, CSNAM, or
         CSSDLL must be transferred to the new segments that take
         their places (CMLM, CLNM, CSNM, and USUD, respectively).
