AND
STATEMENT
FORMAT
The commands and statements presented in this section of the ency
clopedia are governed by consistent format conventions designed to
make them as clear as possible. In most cases, there are several ac
tual examples to illustrate what the actual command looks like. The
following example shows some of the format conventions that are
used in the BASIC commands and s;atements
EXAMPLE LOAD1'program name ".DO. U8
keywords
argument
additional arguments
Ipossibly optional |
The parts of the command or statement that you must type in exactly as
they appear are highlighted in boldface type in the format listing, while
the name of the command is in capital letters. The words that you don't
type in exactly, such as the name of a program, are printed in italics.
When quote marks ("') appear (usually around a program or file
name), you should include them in the appropriate place according
to the format example.
• KEYWORDS, also called RESERVED WORDS, appear in upper
case letters and boldface type. YOU MUST ENTER THESE
KEYWORDS EXACTLY AS THEY APPEAR. However, many key
words have abbreviations that you can also use (see Section 2)
Keywords are words that are part of the BASIC language that your
computer knows. Keywords are the central part of a command or
statement They tell the computer what kind of action you want it to
take. These words cannot be used as variable names.
• ARGUMENTS (also called parameters) appear in lower-case italics.
Arguments are the parts of a command or statement that you select;
they complement keywords by providing specific information about
the command or statement. For example, a keyword tells the com
puter to load a program, while an argument tells the computer which
specific program to load and a second argument specifies which
drive the disk containing the program is in. Arguments include
filenames, variables, line numbers, etc
• SQUARE BRACKETS [1 show OPTIONAL arguments. You
select any or none of the arguments listed, depending on
your requirements.
• ANGLE BRACKETS <> indicate that you MUST choose one
of the arguments listed.
