Warning: This topic only affects Adelia/400.
The system returns to the Adelia exit screen after entry of an environment code. There may be several reasons for this:
The library list is incorrect (one or more libraries do not exist).
The environment output queue does not exist.
One of the libraries in the environment library list is also present in the system library list.
In order to check this, run the IBM DSPLIBL command requesting the name of all SYS type libraries.
