Programming Instructions

There are a number of instructions that are used in connection with

the editing of programs in the Programming Mode:

NEW

Before you enter the first program line, always issue a NEW

statement in the Immediate Mode to clear the printer's working

memory, close all files and clear all variables.

Warning!

If there already is a program in the working memory, it will be

deleted and cannot be restored unless it has been SAVEd.

IMMEDIATE OFF

If you want to write the program without entering line numbers

manually, this statement should be issued in the Immediate Mode

before the first line is entered.

REM (')

To make the program easier to understand, you can enter remarks

and explanations on separate lines or in lines containing other

instructions. Any characters preceded by REM, or its shorthand

version ' (single quotation mark), will not be regarded as part of the

program and will not be executed. REM statements can also be used

at the end of lines, if they are preceded by a colon (:).

END

Usually, subroutines are entered on lines with higher numbers than

the main program. It is a good programming habit to finish the main

program with an END statement in order to separate it from the

subroutines. When an END statement is encountered, the execution

is terminated and all OPENed files and devices are CLOSEd.

IMMEDIATE ON

If you have issued an IMMEDIATE OFF statement before you

started to write the program, you must turn on the Immediate Mode

again by means of an IMMEDIATE ON statement before you can

start the execution, i.e. issue a RUN statement.

LIST

You can LIST the entire program, i.e. make the printer return the

lines to the screen of the host. You can also choose to list part of the

program or variables only. If you have edited the program without

line numbers, the numbers automatically assigned to the lines at

execution will now appear. LIST is usually issued in the Immediate

Mode.
