Variables that Drive Qedit
Qedit has a number of environment variables that allow you to configure and direct the execution of Qedit. These variables identify the type of HP terminal you have, the default function keys, the default settings for the terminal G and H straps, and other options.
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, Qedit cannot lock the keyboard; be careful not to type during terminal identification in this case.
Qedit sets three variables to remember your terminal state: RCRTMODEL, RPCVERSION and RCRTWIDTH. If you run Qedit and these variables are already set, Qedit does not need to do the status requests of your terminal. To reset these variables and force Qedit to re-identify the terminal, use the Set Visual Stop command. You can set a fourth variable, RCRTSTRAPSGH, to request nondefault handshaking in Line mode. The fifth variable, RLABELDEFAULT, is described under "Function Key Label
