PROGRAMMING
A program features lines of commands, but each
line has a number. The number tells the computer in
what order to read the program, lowest being read
first, such as this:
10 PRINT "ANYTHING"
Nothing seems to happen when you press
N . The line is entered in the computer, but
it doesn't do anything. You need to tell it to execute
(or RUN) the program^Youjjo this by typing RUN
and pressing the itfTURN key. Then the computer
goes through each line in order and carries out what
each line tells it to do.
Basic 3.5 Keywords
• The keywords in BASIC 3.5 may be divided into
three types:
— COMMANDS
— STATEMENTS
— FUNCTIONS
• Commands are keywords that are most often used
in direct communication (with no line numbers). An
example of a command keyword is LOAD.
• Statements are keywords that usually appear in
numbered program lines. PRINT is a statement
keyword.
• Functions (as shown in the Numbers review) can be
used in either fashion. Instead of carrying out a com
mand, the computer returns numbers or letters.
