To run EDIT/3000 in an interactive session, initiate the session with the MPE :HELLO command, then use the MPE :EDITOR command as shown in the following example.
Once accessed, EDIT/3000 displays a slash (/) as a prompt character and waits for a command. The ADD command causes EDIT/3000 to prompt for input by printing a line number. Input then is entered from the terminal. To terminate the ADD command, two slashes may be used as in the example, or CONTROL Y may be used (press and hold CONTROL (or equivalent), and press Y). EDIT/3000 responds by displaying..., then displays another prompt for another command. The LIST ALL command causes EDIT/3000 to copy all records in the WORK file to the OUTPUT file (the standard list device—the terminal in this case- unless specified otherwise). The END command terminates EDIT/3000 operation. Note that EDIT/3000 asks if it is OK to clear (the WORK file). If the response is YES (or Y), EDIT/3000 operation terminates and MPE/3000 prints the message END OF SUBSYSTEM. If the response is other than YES (or Y), EDIT/3000 displays a message stating that the clear is not confirmed and then displays a prompt character for another command.
If the contents of the WORK file have not been saved with a KEEP command, the WORK file contents will be lost when a CLEAR is confirmed.
