To correct it, you have to add a definition for a variable called NAME. The error message indicates that NAME is not defined.It is the line that tried to display the "name" variable. Page back in the listing to find statement 2 (on the left side of the listing). The error message has a statement number (statement 2). Return to the beginning of the file and enter RNF7030 on the search line, then hit F16 to locate the error message in the listing. Page up a bit until you find the list of the error messages, then take note of the error message with the highest severity (the RNF7030 message). Use option 5 on the HELLO spooled file and use the B command to go to the end of the listing. If you are using SEU, use the WRKSPLF command and then use F18 to get to the end of the list of spooled files.It highlights the line that tried to display the "name" variable. If you are using RDi, click the RNF7030 error in the Error List Window.Delete the old version of the program by using the DLTPGM command.It puts up a message saying "DSPLY Hello World".Use the CALL command to call the HELLO program, substituting the name of your library for yourlibrary.(If you are using PDM, you are already logged on.).In that case, use DSPJOBLOG, then F10, then F6, to see the output.) If you decide not to use WRKOBJPDM, or if it's not available, then your program just ends without letting you see the DSPLY. You don't actually need to do this step to call your program, but because of an oddity in how the system determines whether to halt your job to show you a simple DSPLY message, it's convenient to get into a screen where the job halts. (The WRKOBJPDM command puts you into a list of the objects in that library.

That you have some prior knowledge of IBM i (also known as AS/400, iSeries, System i).That you have no prior knowledge of RPG III.But 7.1 will be sufficient for most of this tutorial.) If so, this will be noted with the example. (There may be some coding examples that require later releases.
