locationSpec in asynchLink element

The locationSpec property of the asynchLink element in the linkage options part specifies how the CICS® system identifier of a remote transaction is defined:
CICS
Specifies that the location for the remote transaction is defined in the CICS program control table (PCT) or in an RDO TRANSACTION entry.
PROGRAMCONTROLLED
Specifies that the location for the remote transaction is obtained from the sysVar.remoteSystemID system variable when the program invokes the vgLib.startTransaction system function. The location is passed to CICS by way of the SYSID keyword on the EXEC CICS command.
You can find more information on the sysVar.remoteSystemID system variable and the vgLib.startTransaction system function in the topics "remoteSystemID" and "startTransaction" in the EGL Language Reference.
