Interactive Mode Operations During interactive operations, the user enters commands one by one at the terminal. RJE is using $STDINX (the default from the :RJE command) as the command file. See Chapter 5, "Using RJE in Programmatic Mode," for interactive mode operations in programmatic mode. Starting Interactive Mode Interactive mode starts with the entry of the :RJE command (MPE). Following the resulting start message from the system, RJE displays a # prompt on the screen for your entry of the first RJE command. Ending Interactive Mode Interactive mode is ended with use of the #RJEND command. This transmits an EOT control character to the remote processor. It then performs a line disconnect operation and terminates the RJE subsystem. Command Files After a command file specified in an #RJCMDFILE subsystem command has been processed, RJE begins processing subsystem commands from the default command file, $STDINX. If the command file specified in the subsystem command #RJCMDFILE cannot be opened, $STDINX will become the command file. Error Handling Errors occurring during execution cause display of an error message followed by the # prompt. [CTRL]-Y If a command file specified in the #RJCMDFILE subsystem command contains a [CTRL]-Y interruptible command and a [CTRL]-Y is entered, subsequent commands will not be executed and the command file will be closed. Control will return to the interactive terminal. If a [CTRL]-Y is entered while an #RJCONTINUE error recovery is in progress and before a transmitted data set is received or all the commands in a command file are executed, data set transmission will conclude, processing will stop, and control will return to the interactive terminal. If a command file other than $STDINX (the default) is specified with the :RJE command, and a [CTRL]-Y is entered during a [CTRL]-Y interruptable command, the remaining commands in the file will not be processed and control will return to the interactive terminal. Special Forms The use of special forms is accomplished by the capabilities of the HASP, ASP, or JES system of the host computer and by the spooler subsystem of the HP 3000. Example 7 illustrates the use of special forms with JES2.
