Line Mode Advantages
RISE is primarily a line mode editor. Line mode is effective because of the speed with which commands,
one at a time, are sent to RISE for execution. Also, the effects of a command's execution are shown to you
on the screen so that you see exactly what has occurred. For example, when you give the DELETE
command and press the carriage return, RISE will display the lines being deleted.
Another advantage of Line Mode is its use of the terminal's display memory. Using the LIST command you
can fill the screen and memory with text, then scroll up or down, or call the next or previous page for
review, by pressing the terminal's special keys.
Block Mode Advantages
In Block Mode, you can make numerous changes to the data on the display and send them to RISE by
pressing the ENTER key once. Your special function keys (softkeys) are activated to give you what is,
effectively, pushbutton control. The purpose of the special function keys varies with Block Mode
commands you have entered. Descriptive softkey labels appear at the top of the screen with each change of
key function.
Commands Restricted to Modes
Certain commands operate only in Line Mode; others are restricted to Block Mode. Some work in either
mode. If you give a command pertaining to one mode while in the other, RISE will automatically shift to
the correct mode for that command. For example, if you enter the SHOW command while in Line Mode,
RISE immediately shifts to Block Mode, and a display of RPG source lines will appear on your screen,
