HP RPG/XL Utilities-Part 2 RISE

Modes of Operation 

Line and Block Modes 

RISE operates in Line or Block mode using the terminal's powerful
capabilities to their fullest.  Each mode offers you its own unique
advantages.  Line mode is similar to EDIT/3000.  You type in lines in
response to a ">" prompt.  Typing errors can be corrected by backspacing,
which erases the errors and allows you to retype the line as it should
appear.  When you press the carriage return you send the line to RISE for
execution.

Block Mode resembles VPLUS. You enter anything you wish on the screen in
unprotected data fields.  You may correct typing errors or alter the
information displayed as needed.  You position the cursor, using the
cursor control keys and editing keys to make your changes directly on the
screen.  Afterwards, you press the ENTER key to send all the data on the
screen to RISE for processing.

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, allowing you to
make any changes directly.  Thus, all commands may be entered while in
either mode.
