The following table shows the most common environment variables that you
might have been using when using Workbench and its add-ons to develop
mainframe applications, and shows the equivalents in Mainframe Express.
In the few cases where the table says to continue using the environment
variable, you need to set it before starting the IDE - for example, by
starting the Mainframe Express Command Prompt and using the command line
to set the environment variable and to start the IDE.
