LIST
This command displays each line of your program starting with the lowest line number.
Each time you press
Enter
, the next lines are displayed. You can stop this by pressing
the
Shift
and
Break
keys. If you enter the command with a line number after the word,
i.e., LIST 50,
PRECOMPUTER PRESTIGE
TM
will list the statement at line 50.
RUN
This command instructs
PRECOMPUTER PRESTIGE
TM
to begin executing each BASIC
statement with a line number that was typed into memory. The computer will start with
the lowest line number and proceed up to the highest numbered statement.
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 the line number and press
the
Enter
key. The statement will appear on the display. Use the
and
keys to
move the cursor. Use the
Del
key to remove an unwanted character, or type in a new
character.
You can type in line-numbered BASIC statements in any order. The
PRECOMPUTER
PRESTIGE
TM
will sort them out for you and
LIST
them or
RUN
starting with the lowest
numbered statement to the highest numbered statement. It is a good idea to number your
lines in increments of 10 (10, 20, 30...) or 100 (100, 200, 300...). This way you will 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 re-typing the entire line.
AUTO
When you want to type in the program, you need to type in the line number before the
statement. With the
AUTO
function, the line number will generate automatically.
e.g. AUTO
generate the line no. starting from 10 with increments of 10
AUTO 100
generate the line no. starting from 100 with increments of 10
AUTO 100, 5 generate the line no. starting from 100 with increments of 5
i.e.
100
105
"
"
To end the
AUTO
mode, press
Enter
without input or press the
Shift
key
and the
Break
key at the same time
.
