There are 4 files in this fix, unZIP them to either a diskette or directory. In order to use these
files, you will need to either copy them to the ROOT directory of the BOOT drive, and then
restart your system, or use the Install diskette and ESC to the A: prompt and replace these
files in your OS2\DLL directory. The changes will then take effect when you reboot your
system.

The files in the ZIP files are -

Title: REXX: VALUE(.."OS2ENVIRONMENT"..) TO SET ENV HOSES PIB INFO.             
                                                                                
Problem Description                                                             
                                                                                
"RexxStart()" Bug                                                               
                                                                                
I use RexxStart() from a "C" program to call a REXX procedure. I have           
recently diagnosed a problem where if I set an environment variable in          
this rexx procedure, the called programs environment is corrupted (as           
a "C" "getenv()" call fails to retrieve a variable that is known to             
exist.                                                                          
                                                                                
Depending on the change to the environment, I sometimes get an invalid          
value returned in the "pib_pchcmd" field from a "DosGetInfoBlocks()"            
call.  This invalid value is the tail part of the new variable value.           
Thinking that the bug may only occur when expanding the size of an              
environment variable or the environment, I tried to shorten the path            
variable, this removed the problem with "pib_pchcmd" being corrupted            
but still caused the "getenv()" to fail.                                        
                                                                                
Note that the "getenv()" does not always fail, it obviously depends             
on the change.
