Here is an overview:
- In Attachmate, select options, global pref, advanced
- Assign the active session to a HLLAPI short name, for example, B
- Open the Unicenter OM Document Viewer Emulation window
- Choose HLLAPI from the Configure Connection menu (This is the remote menu in the emulator window)
- Choose Attachmate for Windows
- Enter the HLLAPI short name (B) from above, in the Session ID window
- Select HLLAPI32.DLL from the HLLAPI DLL filename list
- Verify that Attachmate is in the PATH for your operating system.
