APPC Mode
A mode is associated with an LU-LU pair, and determines the session properties for that pair. One of the key mode properties is the Parallel Session Limit. This limit determines whether an LU-LU pair can perform only one interaction at a time or multiple concurrent interactions.
Parallel sessions are used only with independent APPC. If parallel sessions are to be allowed with an LU-LU pair, the local LU must be independent, and the remote LU in the pair must support parallel sessions.
If the LU-LU pair can have multiple parallel sessions, other mode properties, such as Minimum Contention-Winner Limit, determine to what extent each LU can initiate interactions.
The following table lists the modes provided with Host Integration Server.

| #BATCHC | Batch-oriented sessions using compression |
| #BATCHSC | Batch-oriented sessions that employ a minimal level of routing security |
| BLANK | Sessions using a default mode name, encoded as eight blank EBCDIC spaces in BIND |
| #INTER | Interactive sessions |
| #INTERC | Interactive sessions using compression |
| #INTERSC | Interactive sessions that employ a minimal level of routing security |
| QPCSUPP | All sessions with an IBM i computer |
