Global environment data area (ENV)

The ENV data area provides information which is common to all exit types.

Two special fields are provided in this data area: USER_1 and USER_2. Initially, Z Abend Investigator initializes these fields to blanks, but no reinitialization is performed between the invocation of the first and the last user exit. These fields can be used to pass information, for example the address of a data area, between exits.

A detailed description of the ENV data area is available in ENV - Common exit environment information.
