RUN

This command instructs PRECOMPUTER POWER PAD™ PLUS 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. Type EDIT and the 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 type in a new character.

You can type in line-numbered BASIC statements in any order. The PRECOMPUTER
POWER
PAD™ PLUS 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 between two existing ones by using a
line number that doesn’t exist. To delete an existing line-numbered statement, type the
line number and press the ENTER key. You can also change an existing line by re-typing
the entire line.

AUTO

When you want to type in a program, 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.

CONT

This command causes the program to resume executing after encountering the BASIC
command called STOP. The program will be carried on with the next statement after STOP.
Type CONT to resume the program after you press the SHIFT and BREAK keys.
