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).
