Display station passthrough is an example of an application that uses APPC communications. You can use display station passthrough to sign on to another system that is connected to your system through a network.
The following table shows examples of passthrough requests (STRPASTHR command) and how the target system handles them. For display station passthrough, the system uses the basic elements of APPC communications and the remote sign-on (QRMTSIGN) system value.
| Values on STRPASTHR command | Target system | |||
|---|---|---|---|---|
| User ID | Password | SECURELOC value | QRMTSIGN value | Result |
| *NONE | *NONE | Any | Any | The user must sign on the target system. |
| A user profile name | Not entered | Any | Any | The request fails. |
| *CURRENT | Not entered | *NO | Any | The request fails. |
| *YES | *SAMEPRF | An interactive job starts with the same user profile name as the user profile on the source system. No password is passed to the remote system. The user profile name must exist on the target system. | ||
| *VERIFY | ||||
| *FRCSIGNON | The user must sign on the target system. | |||
| *VFYENCPWD | *SAMEPRF | An interactive job starts with the same user profile name as the user profile on the source system. The source system retrieves the user's password and sends it to the remote system. The user profile name must exist on the target system. | ||
| *VERIFY | ||||
| *FRCSIGNON | The user must sign on the target system. | |||
| *CURRENT (or the name of the current user profile for the job) | Entered | Any | *SAMEPRF | An interactive job starts with the same user profile name as the user profile on the source system. The password is sent to the remote system. The user profile name must exist on the target system. |
| *VERIFY | ||||
| *FRCSIGNON | The user must sign on the target system. | |||
| A user profile name (a name different from the current user profile for the job) | Entered | Any | *SAMEPRF | The request fails. |
| *VERIFY | An interactive job starts with the same user profile name as the user profile on the source system. The password is sent to the remote system. The user profile name must exist on the target system. | |||
| *FRCSIGNON | An interactive job starts with the specified user profile name. The password is sent to the remote system. The user profile name must exist on the target system. | |||
