Segmenter
You can invoke the Segmenter from within Qedit using the :Segmenter command, but then you must type your segmenter commands directly and wait for them to complete. You can :Stream a job that invokes the Segmenter, but that does not execute on your terminal where you can see it. Or, you can Run Segdvr.Pub.Sys with a Stdin file that contains your Segmenter commands.
/list segprg23 1 usl $oldpass 2 auxusl splusl.source 3 copy segment,qhelp 3 copy segment,dateformat 4 exit /:run segdvr.pub.sys;stdin=segprg23
You can use Prep and you can specify default values for RL and Maxdata (Set RL and Set Maxdata) or use QMAP to make the PMAP readable.
