Writing OS-independent programs in Object REXX



If you want to write operating system independent programs using Object 
REXX, you should keep the following differences between Object REXX for 
OS/2 and Object REXX for Windows 95 / Windows NT in mind: 



   *  in the Windows version, the environment is process-local 



   *  in the Windows version, host commands are executed in a new process 



   *  on Windows 95, host commands always return 0 



   *  Object REXX on Windows does not support SOM, and the DBCS support is 
      not documented 



   *  in both versions (Win95 and OS/2) you should use VALUE( envVarName, 
      envVarValue, 'ENVIRONMENT' ) to set or read environment variables 



   *  in both versions (Win95 and OS/2) you should use VALUE( envVarName, 
      .NIL, 'ENVIRONMENT' ) to delete an environment variable 
 



 More information about Object REXX for the Windows platform can be found 
 at the Object REXX home page (see Internet - Web Pages).
