The CF07 and CF08 keys are alternative page keys. During display of the subfile, if the user presses the CF07/CF08 key or a Page key, the OS/400 program pages the subfile. If the OS/400 program cannot page the subfile without going beyond the end or beyond the beginning, a message is displayed indicating the key is not valid at that time (PAGEDOWN/PAGEUP not specified).
