EDIT
Use the EDIT command when you want to change a statement that has been
typed into memory without re-typing the entire line. Just type EDIT and line number
and press the ENTER key. The statement will appear on the display. Use the
LEFT-ARROW and RIGHT-ARROW keys to move the cursor. Use the DEL key
to remove an unwanted character, or simply type in new characters.
Example:
10 INPUT B

10 INPUT B_

You can type in line-numbered BASIC statements in any order. The
PRECOMPUTER 2000 will sort them out for you and LIST them or RUN them
starting with the lowest numbered one . It is a good idea to number your lines
in increments of 10 (10, 20, 30 .. . ) or 100 (100, 200 , 300 .. . ). This way you have
room to add more statements if you decide to change your program in the future .
You can insert an entirely new line in a program by using a line number that
doesn't exist between two existing ones . You can delete an existing line-numbered
statement by merely typing the line number and pressing the ENTER key. Of
course, you can change an existing line by merely retyping the entire line .
END
Line # END
The END statement is used as the last command in a program . It stops the
program .
Examples :
160 END
999 END
