You can specify multiple transmitters (and receivers) for a line as described in Specifying transmitters and receivers. For individual SYSOUT transmitters, you can also specify work selection characteristics based on the size of SYSOUT files as described in Specifying work selection values for NJE transmitters.

NJE file sizes can range from very small (for example, one record, such as a Netmail acknowledgment) to very large (millions of records). After a transmitter has selected a file, it does not interleave it with other files or voluntarily interrupt the transmission until that file is completely transmitted. If the line drops or the transmission is otherwise interrupted, the entire file must be retransmitted from the beginning.

You can use the work selection (WS=LIM) parameter on the L(nnnn).ST(n) statement to cause a SYSOUT transmitter to select files based on their size, so as not to tie up a transmitter a long time with very large files. This allows a transmitter to be available for timely delivery of small files. See Specifying work selection values for NJE transmitters for more information.
