Entering and Editing Program Lines On a blank template, you can begin entering commands for your new program. Program name, which you specify when you create a new program. Enter your program commands between Prgm and EndPrgm. All program lines begin with a colon. Note: Use the cursor pad to scroll through the program for entering or editing commands. Use 8 C or 8 D to go to the top or bottom of a program, respectively. You enter and edit program commands in the Program Editor by using the same techniques used to enter and edit text in the Text Editor. Refer to "Entering and Editing Text" in the Text Editor module. After typing each program line, press ¸. This inserts a new blank line and lets you continue entering another line. A program line can be longer than one line on the screen; if so, it will wrap to the next screen line automatically. Note: Entering a command does not execute that command. It is not executed until you run the program. Entering Multi- Command Lines To enter more than one command on the same line, separate them with a colon by pressing 2 Ë. Programming 580
