Pico is a simple text editor available on the
mode machine. Think of it as a very primitive version of Microsoft Word!
While editing a document, regular text can be entered directly; however, editing
commands are executed using control-key combinations.
Let's say you want to create a new C++ source code file named "prog.c" in your
current working directory (folder). You would
simply type "pico prog.c" (no quotes) at the mode prompt.
Now let's say you want to edit
an existing file named "Prog.java". First, you must change into the directory in which
Prog.java is located, and then
you would type "pico Prog.java" (no quotes) at the mode prompt. Very easy!
The bottom two lines contain most of the commands available in pico. Commands
such as ^X mean "press and hold the control (ctrl) key, then press the "x" key".
The most useful commands are the following:
- ^O - Save your changes (listed as "WriteOut")
- ^X - Exit editor
- ^W - Find a word (listed as "Where is")
- ^K - "Kuts" a line of text
- ^U - "Unkut" (paste) the previous "kut" line
- ^C - Display the current line number
Some tricks you may want to use:
Sometimes you need to get to a certain line in your file where
a programming error has occured. Hold down the control key and then hold down the "c" key (to display your
current line number), and then use the up and down arrow keys while keeping the control and "c" key
pressed. You will see the line number continually update as you scroll through the text. In this fashion
you should be able to arrive at your location quickly.
To cut and paste large amounts of text, start by placing the cursor at the beginning of
the text you wish to cut. Do a "^ ^" (ctrl-shift-6) to mark this location. Next, use the down arrow key
to highlight as many lines of text after your mark as you wish. Now, when you "kut" and paste,
you will be performing
those operations on the large block of text you have just highlighted.
Also, if your window supports it, you may use the cut/copy/paste items from the Edit
pull-down menu at the top of the screen. These should work similar to any other windows
application. If you are using these features and you are having trouble using your mouse to
highlight a large amount of text, use the trick in the previous paragraph to do your
