RJE lines are the logical connections between JES2 and VTAM®. Use the $T LINE(nnnn) command to specify the characteristics of a line, diagnose line problems, and disconnect a line. This command allows you to change many of the parameters specified on the LINE(nnnn) initialization statement. Use the $D U LINE(nnnn) or the $D LINE(nnnn) command to display current values through the $HASP880 message. In particular, the RMTSHARE= parameter displays whether or not a line can be dedicated to an RJE workstation.

You can dynamically define RJE workstations through the $ADD RMT(nnnn) command only if all RJE lines have been predefined at initialization.

Because teleprocessing lines are not considered active at JES2 initialization, each line must be activated using a JES2 $S LINE(nnnn) command. You issue this command through a command stream (for example, in the JES2 initialization data set), through the automatic command processor, or in a job stream. A line is dynamically allocated when activated; you deactivate a line using the $P LINE(nnnn) command. You can restart a line using the $E LINE(nnnn) command.
