Accessing Files And Programs As mentioned in chapter 1, you must specify a file name when you start HP EDIT in order to conduct a session. However, once you have specified a file name and the session begins, you have several options for accessing other files within a session. You can: * Specify another file to edit * Insert the contents of another file * Start one or more child sessions You can also issue MPE commands or run programs from within HP EDIT. Texting in Files Whenever you request HP EDIT to read in a file from an existing session, the action is referred to as texting in another file. You use the Text File command to text in an existing file or create a new file. In either case, you must save the current text or discard editing changes before you can text in another file. When you want to create a new file that does not currently exist, HP EDIT opens an empty file. The Set Options parameter New File Type determines the file type, which is unnumbered by default. You can change the file type to a numbered file by changing this parameter from the Set Options screen before adding any text. Refer to "Line Numbering" in this chapter for more information about handling numbered and unnumbered files. Joining Files You can also access the contents of another file by inserting it into the current file. This process is called joining. You use the Join File command to join another file into the current one. Refer to the Join File command in chapter 4 for complete information about command usage. Starting Concurrent Sessions HP EDIT enables you to edit several files simultaneously in which HP EDIT handles each file as an independently activated process. You can execute the Activate Next Process command from the current session to access a new or existing file [REV DEL]. The session you access is called a child session. You can create as many child sessions as desired. You can return to a parent session by executing the Activate Previous Process command. Accessing Programs You can issue MPE commands while editing and can run almost any program from within HP EDIT. Often you can edit, save, compile, and execute code from within HP EDIT. Refer to the Break To MPE, Execute MPE Command, Run Program, and Run TDP Formatter commands in chapter 4 for information about these capabilities.
