CLEARING THE SCREEN
There will be times when your screen is too crowded, or you want to
reorganize what you've typed. or you're just plain unhappy wan what's
on the screen and want to banish it to wherever it is that print goes
once a leaves the monitor screen. There are a few ways to accomplish
this, leaving the programs in your computer's memory intact or clearing
the memory as well as the screen
One way to clear the screen is to hold the SPACE SAP down, until it
clears the 1000 spaces on the screen (for a couple minutes or so) If
you've read this far into the User's Manual, chances are that you have
the patience to clear the screen like this. but also the intelligence to
realise trtat there has to be a better way. Here are some better ways'
1. Hold the DOWN CURSOR key + until everything on the screen
scrolls off the top of the screen
2. Press the SEIPP and C131/110111E keys together This clears the
screen and repositions the cursor at me top left-hand corner. (the
'home position)
3. Type
SCNCLR and press MEOW
This is a BASIC language command teal your computer interprets as
instruction to clear the screen
4. Press the RESET BUTTON. Tnis resets the machine, bringing back
the starling Screen and clearing all programs out of your computer's
memory.
If you want to clear the computers memory but not the screen, type:
NEW and press AMIE
This is a BASIC language command that tells the computer to empty its
memory. The 16 in the Commodore 16 refers to the amount of space
(16K) mat your computer has to store programs, known as the memory.
When you clear the screen with any of the first three methods, you
clear the characters on the screen, but whatever is in your computers
memory stays there. This means you have less space for new
programs. The last two methods erase what is held in your computer's
memory, so that you again have the full amount of space available for
new programs.
SCREEN WINDOWS

workspace. Everything you type (lines you typo. LISTings of programs,
etc.) after setting a window appears within the window's boundaries.

STEP 3 Move the cursor to the position you want to be the bottom

the
window. press the 4:11MUZ011a key twice. The window is then
