JCWs That Drive Qedit
Qedit has a number of JCWs (Job Control Words, a feature of MPE) that allow you to configure and direct the execution of Qedit. Most of these have to do with the type of terminal you are using, but QEDITMGRTRACE allows you to see your configuration commands and QEDPARMBITS allows you to specify the Parm= values without a Parm= option on the Run command.
When you run Qedit, it must identify the type of terminal that you are using and determine what function-key labels to display. Qedit does status requests to detect the model number and the current width of display memory. This information is used to enhance the functioning of Qzmodify, Visual, Help and List. Qedit locks the keyboard during terminal identification and discards any user input that manages to get through. However, if you have Reflection typeahead enabled, this is not possible; be careful not to type during terminal identification in this case.
Qedit sets three JCWs to remember your terminal state: RCRTMODEL, RPCVERSION and RCRTWIDTH. If you run Qedit and these JCWs are already set, Qedit does not need to do the status requests of your terminal. To reset these JCWs and force Qedit to re-identify the terminal, use the Set Visual Stop command. You can set a fourth JCW, RCRTSTRAPSGH, to request nondefault handshaking in Line mode. The fifth JCW, RLABELDEFAULT, is described under “Function Key Labels”.
